I need some help with a problem I am experiencing with my 4-door Skyline. The problem is with the driver side power window.

A while ago when I rolled the window down I would hear a whirring sound after the window was completed wound down. Thought that it might be the power window motor going bad and after the window not rolling up on a few occasions, I went and bought a new motor and had that installed.

Now the same problem exists with the new motor. You can wind the window down however the motor doesn't disengage and you hear a whirring sound even though it has reached the bottom on the door. When I try winding the window back up, it moves up for a few inches and then stops. Does wind up completely and there is still the annoying whirring sound. You have to tap the control switch to actually stop it from whirring and probably burning the motor out.

I changed the master control switch as I had a spare one and the problem still exists. Through it might have been a problem with the tracks for the window not being lubricated enough. Bought some of that super slick silicone lubricant and gave the tracks a liberal blast. No luck with either of the two.

I was wondering if there is a relay that controls the window and for some reason the motor is not getting enough current to wind the window up. It probably works going down as it is acting with gravity and takes some of the load off of the motor. I tried looking for a power window schematic online but I haven't found anything yet.

Is there anyone who can assist me with this problem?

A mate of mine had a similar problem and a new motor fixed his problem. Sigh, mine had to be more complex.

All help appreciated.

I have a slightly similar problem with my 2 door :D

My window goes up fine but i can hear it clicking like its still trying to go up (or down when at bottom), even though its already as far up (or down) as it can go. I can stop it by tapping the up or down button once. It only happens on auto-up and down function. Mine doesn't make a whirring noise though.

Was going to replace the switch box and see how that goes.

Anybody know if there is an 'initialisation' procedure you can perform on the power windows at all, to let the motor know its end stops?

Yup. It is the auto up/down feature that I experience the problem with. The whirring noise I am referring to is the sound of the motor seemingly trying to turn. Did some more research last night and I believe the problem is isolated to either wiring or a control relay(if any) for the window. Retested both master control switches and window motors and the same thing is happening for both.

Today I will try and see if I can trace anything.

I pulled down the entire driver side door, checked that there were no broken or stripped wires. I finally came to the conclusion that the assembly for the auto p/w is faulty. Haven't been able to test it yet however I have removed it from the car and asked a buddy to borrow his to see if the problem still exists.

Have attached photos of the nasty device. Completely sealed so I can't open it to see if anything has burnt out on the inside

Ok guys n gals I am thoroughly stuck right about now. Here is an outline of the things that I have done so far:

1. Checked wiring for breaks, arcing wires and stripped wires.

2. Checked power window motor (x2)

3. Checked master control switch (x2)

4. Check power window amp (x2)

5. Greased the runners for the window

After doing all of that my problem still exists. I really don't know what could be going on.

Have checked the window assembly gearing to make sure it is meshing with the motor gear properly.

Does anyone have any suggestions?

Open up this box - you can do it with a flat screwdriver or two.

In the box IS THE PROBLEM. There are some solenoids in the box that control the auto up/down.

The solenoids are large and heavy, and so the constant opening and closing of the doors has "shocked" the PCD (circuit board) so that the solder joints for the solenoids have cracked.

Open it up and you will see some hairline cracks - they maybe almost impossible to see. re solder these cracked joints and your problems will be solved.

Went by a buddy who opened the box and checked it out for me. He had a similar problem, which as you mentioned was due to

dry joints in the soldering. There weren't any such problems with the circuit board in my box. I even got another buddy to lend me the amplifier box from his S13 and I had the same problem. The window would go down, but not come back up.

We even connected the exposed board to the door and watched the solenoids open and close perfectly each time the switch was operated.

  • 8 months later...

I have a similar problem.

My passenger side window will only go up when it's cold outside.

When it's cold on winter mornings, it will work fine, until I start driving, a few minutes after leaving the house, it damn thing wont go up :@

I've just switched it off with the window lock button for a while, but on the weekend my son put it down a bit :huh:

So, I'm going to pull the doors apart and fix what is probably a dry solder (due to it working in different temperature conditions) but I need to know if there are one or two control boxes....

Is there one in each door, or just a single in the drivers door?

Also, if I can't fix, are the R34 control boxes the same as R32, R33 or other Nissans?

All help appreciated.

BASS OUT

I fixed mine today at lunch time.

Pulled the drivers door skin off and removed the little control module.

Opened it up, found there to be a little bit of corrosion on the PCD.

Used an eraser and removed that corrosion.

Put it all back together, and whizz bang she's all fixed.

:P

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
