Hi All,

My drivers side window regulator broke recently and after looking and asking around, i got a new regulator from Nissan (no motor) which needed installing.

This tutorial will be good for you is you have a S2 R33 coupe where you need to change the regulator and/or the window motor.

I didn't take any pictures but if I get a chance ill pull the door apart again and get some.

Just a note before hand, i really recommend getting the plastic inner weather shield from Nissan as your old one will probably get torn up in the process.

1. Get all required tools and parts

a. Long 10mm socket

b. 12mm socket

c. 3" socket extension

d. Phillips head screwdriver

e. Fat Phillips head screwdriver (only required isremoving motor from regulator)

f. Flat head screw driver

g. Grease

h. Whatever parts you need (recommended to also buya new weather shield (80860-22U00)

2. Wind down window to the bottom

3. Undo the three screws along the bottom of thedoor trim

4. Remove the plug in the door pull cup and undoscrew

5. Remove pull cup and window switch assembly andunplug

6. Pull off door latch surround. Trick to doingthis is to use a flat head screwdriver to undo the clip at the top of thesurround. Just wedge the flat head between the surround and trim and flick thetab off.

7. Remove door trim. Start pulling from the bottomand remove.

8. Unscrew door handle support.

9. Remove speaker shroud (4 screws)

10. Remove plastic weather shield

11. Remove any extra glue still on the door panel.

12. Remove car to back of mirror and unbolt themirror.

13. Unscrew belt moulding at end of door.

14. Remove belt moulding

15. Unbolt the 2 fabric covered window guides

16. Unbolt the two window stoppers (next to thewindow guides)

17. Plug the window switch back in and wind thewindow up about 2 inches till you can access the bolts holding the window tothe regulator

18. Get someone to hold the window while you unboltthe window from regulator (2 nuts)

19. Pull the back end of the window from the doorfirst and bring the front through the back too.

20. Unclip the power to the motor

21. Undo the 6 bolts holding the regulator on.

22. Remove regulator and motor.

23. If you have a new regulator and need to swap themotor over then you will need a short and fat Phillips head.

a. I ended up making one but getting a large Phillipshead and grinding it back.

b. The three screws which hold on the motor arevery tight and easy to damage so be careful!

24. Grab your new regulator and adjust it so thegear and motor will line up and hold it in place with a vice grip.

25. Screw motor onto new regulator and make sure itis tight.

26. Grease up all teeth on the new regulator and themoving rails.

27. Before you put the regulator and motor assemblyback into the door, hook it up to the wiring and test it.

28. Slide the regulator assembly back into the doorand put back the 4 bolts and 2 nuts to hold it in place.

29. Connect the power to the motor and test itagain. Make sure the regulator is in a position where you can bolt the windowup again (about 2 inches from the bottom of travel)

30. Slide the window back in the opposite from howyou took it out. Be careful not to scratch any tint you have on it.

31. Line the window up with the regulator and screwin both of the nuts to hold it in place.

32. Move the window to the bottom position.

33. Bolt on the window stoppers at their lowestposition and tighten.

34. Bolt on the window guides at their lowestposition and tighten.

35. Reattach the exterior belt lining and screw inplace.

36. Wind the window up as far as it will go. Do thiswithout auto up.

37. While outside the car, close the door. Measure thegapping front and rear to where the window should be. Remember thismeasurement.

38. Wind the window down again a little and readjustthe window stoppers up the same amount as the gap (mine was about 7mm)

39. Tighten the stoppers and retest where the windowends up. If the stoppers are too high the window will get stuck on the outsideof the door.

40. Once it is in a good position wind the windowdown again.

41. Get your old (or new) weather shield and put itback on the door. Again, I suggest getting a new one from Nissan as it islikely you will test your old one.

42. Screw the speaker back in place.

43. Screw the door handle support back in place.

44. Reattach the mirror and replace mirror cap.

45. Put the door trim back on the door and tighten 3screws along the bottom.

46. Replace the pull cup/window switch assembly andscrew it in place (put the plug back in the pull cup too)

47. Once again, test your window. Might be a good idea to give it a clean now too!

Well, i hope this helps someone in the future, if you have any questions, shoot me a PM.

    • I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.
    • Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too. 
    • Any update on this one? did you manage to get it fixed?    i'm having the same issue with my r34 and i believe its to do with the smart entry (keyless) control module but cant be sure without forking out to get a replacement  
    • So this being my first contribution to the SAU forums, I'd like to present and show how I had to solve probably one of the most annoying fixes on any car I've owned: replacing a speedometer (or "speedo") sensor on my newly acquired Series 1 Stagea 260RS Autech Version. I'm simply documenting how I went about to fix this issue, and as I understand it is relatively rare to happen to this generation of cars, it is a gigantic PITA so I hope this helps serve as reference to anyone else who may encounter this issue. NOTE: Although I say this is meant for the 260RS, because the gearbox/drivetrain is shared with the R33 GTR with the 5-speed manual, the application should be exactly the same. Background So after driving my new-to-me Stagea for about 1500km, one night while driving home the speedometer and odometer suddenly stopped working. No clunking noise, no indication something was broken, the speedometer would just stop reading anything and the odometer stopped going up. This is a huge worry for me, because my car is relatively low mileage (only 45k km when purchased) so although I plan to own the car for a long time, a mismatched odometer reading would be hugely detrimental to resale should the day come to sell the car. Thankfully this only occurred a mile or two from home so it wasn't extremely significant. Also, the OCD part of me would be extremely irked if the numbers that showed on my dash doesn't match the actual ageing of the car. Diagnosing I had been in communication with the well renown GTR shop in the USA, U.P.garage up near University Point in Washington state. After some back and forth they said it could be one of two things: 1) The speedometer sensor that goes into the transfer case is broken 2) The actual cluster has a component that went kaput. They said this is common in older Nissan gauge clusters and that would indicate a rebuild is necessary. As I tried to figure out if it was problem #1, I resolved problem #2 by sending my cluster over to Relentless Motorsports in Dallas, TX, whom is local to me and does cluster and ECU rebuilds. He is a one man operation who meticulously replaces every chip, resistor, capacitor, and electronic component on the PCB's on a wide variety of classic and modern cars. His specialty is Lexus and Toyota, but he came highly recommended by Erik of U.P.garage since he does the rebuilds for them on GTR clusters.  For those that don't know, on R32 and R33 GTR gearboxes, the speedometer sensor is mounted in the transfer case and is purely an analog mini "generator" (opposite of an alternator essentially). Based on the speed the sensor spins it generates an AC sine wave voltage up to 5V, and sends that via two wires up to the cluster which then interprets it via the speedometer dial. The signal does NOT go to the ECU first, the wiring goes to the cluster first then the ECU after (or so I'm told).  Problems/Roadblocks I first removed the part from the car on the underside of the transfer case (drain your transfer case fluid/ATF first, guess who found out that the hard way?), and noted the transfer case fluid was EXTREMELY black, most likely never changed on my car. When attempting to turn the gears it felt extremely gritty, as if something was binding the shaft from rotating properly. I got absolutely no voltage reading out of the sensor no matter how fast I turned the shaft. After having to reflow the solder on my AFM sensors based on another SAU guide here, I attempted to disassemble the silicone seal on the back of the sensor to see what happened inside the sensor; turns out, it basically disintegrated itself. Wonderful. Not only had the electrical components destroyed themselves, the magnetic portion on what I thought was on the shaft also chipped and was broken. Solution So solution: find a spare part right? Wrong. Nissan has long discontinued the proper sensor part number 32702-21U19, and it is no longer obtainable either through Nissan NSA or Nissan Japan. I was SOL without proper speed or mileage readings unless I figured out a way to replace this sensor. After tons of Googling and searching on SAU, I found that there IS however a sensor that looks almost exactly like the R33/260RS one: a sensor meant for the R33/R34 GTT and GTS-T with the 5 speed manual. The part number was 25010-21U00, and the body, plug, and shaft all looked exactly the same. The gear was different at the end, but knowing the sensor's gear is held on with a circlip, I figured I could just order the part and swap the gears. Cue me ordering a new part from JustJap down in Kirrawee, NSW, then waiting almost 3 weeks for shipping and customs clearing. The part finally arrives and what did I find? The freaking shaft lengths don't match. $&%* I discussed with Erik how to proceed, and figuring that I basically destroyed the sensor trying to get the shaft out of the damaged sensor from my car. we deemed it too dangerous to try and attempt to swap shafts to the correct length. I had to find a local CNC machinist to help me cut and notch down the shaft. After tons of frantic calling on a Friday afternoon, I managed to get hold of someone and he said he'd be able to do it over half a week. I sent him photos and had him take measurements to match not only the correct length and notch fitment, but also a groove to machine out to hold the retentive circlip. And the end result? *chef's kiss* Perfect. Since I didn't have pliers with me when I picked up the items, I tested the old gear and circlip on. Perfect fit. After that it was simply swapping out the plug bracket to the new sensor, mount it on the transfer case, refill with ATF/Nissan Matic Fluid D, then test out function. Thankfully with the rebuilt cluster and the new sensor, both the speedometer and odometer and now working properly!   And there you have it. About 5-6 weeks of headaches wrapped up in a 15 minute photo essay. As I was told it is rare for sensors of this generation to die so dramatically, but you never know what could go wrong with a 25+ year old car. I HOPE that no one else has to go through this problem like I did, so with my take on a solution I hope it helps others who may encounter this issue in the future. For the TL;DR: 1) Sensor breaks. 2) Find a replacement GTT/GTS-T sensor. 3) Find a CNC machinist to have you cut it down to proper specs. 4) Reinstall then pray to the JDM gods.   Hope this guide/story helps anyone else encountering this problem!
