ok, ive read just about every post about this subject on these forums.

now, here are my problems.

I believe the actuator motor for the air conditioning is faulty, I cant switch from hot to cold without going under the dash and help turn the motor.

Also it only works on the feet and for front demister, I cant get it to work out of the front vents.

i read somewhere to contact nissan about this motor, so i did. i contacted essendon nissan in melbourne and here is the response i was given:

I have had a look at the actuator for the R33 and found there are actually four on the heater. There is a mode actuator (mode normally means the change from feet to demist to dash etc.) and I think from your description this may be your prolem as far as changing modes goes. This part is available in Melbourne at one days notice. The price is $175 including GST. Being an import part this would need to be paid in full at time of order and there is strictly no cancellation or return on these parts.

the motor above the drivers left foot I think is the fresh air actuator which would change from fresh to recirculate or in other words block the outside air intake. This part is available from Japan with around 2-3 weeks delay. The price is $190 including GST.

There is also an actuator on the upper part of the fan or blower casing. This part is described as a air intake actuator and I am not sure exactly what this does as it seems by description to have the same job as the second one I mentioned. However where it is located doesn't seem to me to be able to block air intake from outside the cabin. This also would need to come from Japan and the price is $150

Also there is an actuator called air mix actuator. This may be related to your hot/cold problem but we do not work on import Skylines here and have no diagnostic equipment to suit them. I cannot therefore give you any advice regarding your fault code. This actuator is $190 and would also have to be ordered from Japan. All parts from Japan need to be paid in full at time or order and there is also no cancellation or return.

ok, thanx to that response, im more confused. i didnt know there were so many motors. what i need from you guys is to tell me which part/s i need to solve my 2 problems. i want to get this problem solved before it gets to hot as this is my 3rd year with this problem, :D

any help is appreciated

thanx

Ok well if it is one of your motors all you need to do is simply go to a wreaker and pick up any 12v motor assembly from side mirror or heater boxes etc..

Open up your suspect motor and chamge it over/solder it in the replacement one.

Perhaps before you do that take it to an autoelec and he can test the little motor.

I had an issue that after I changed my heater core the climate control would not swap from cold to hot without me helping.

Took out the motor from the drivers footwell and off to an auto elec to get it checked.. It was fine.. Very odd..

The auto elec suggested the issue was that the small flap that locks the pivot rod in the passenger footwell was secured back to front.

I did not believe this would make a difference. But I took the auto elecs advice and it seemed to make the difference.

thanx for the response. i might give that a try, replace the motor itself with another.

im 100% sure (ok 99% sure) that the motor that goes on top of the heater box up near the top of the dash is the one i need to fix the problem i have with not being able to switch to face vents.

as for the hot to cold problem, the only way i can get it to switch it to say go from cold to hot with the arrows (say to 32 degrees) the motor under the dash near the drivers left foot starts clicking and by looking at it, it looks like it doesnt have the strength to turn the pivot handle to switch it to hot by pulling or pushing on the pivot rod.

i wish i could just take it to someone in melbourne that is experienced with this sort of thing and can tell me for sure instead of me just guessing.

I forgot to mention the motor that your having problems with the face vents one is now staring to click its arse off on my car..

Damm climate control..

Can't be stuffed pulling the dash out again so I will wait till it fails.

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
