A/c Problems On Gtr 32

[bernie777]

Hi guys, I guess this is a common problems which u guys have seen and experienced.

I only have hot air coming out from the front of my windscreens when I switch my a/c on. I did some research and found out that I have received the following fault codes from the a/c diagnostics. Code 21( outside air sensor), code 25 (sunload sensor) and code -26(PBR short circuit) that's what I took off the manual. If you have a negative on your code, it means you have a short circuit.

I tried playing around with the actuator underneath the driver side compartment. Removed the actuator and cleaned all the gears. Ending up breaking one of the stems which the gears sit on. So got to get another one I guess.

So the big question is, where can I get the sensors n the god damn actuator that I broke??? Location for the sensors with pictures would truly be mighty helpful!!!

PITA - good luck (I'll keep an eye on this thread)

There is an R32 AC thread already in the forums but from memory it's not going to help with all 3 issues.

Sunload sensor only works when your in the sun

Outside air sensor I believe is near the horns and you should be able to get 2nd hand as a lot of guys remove all the AC components

Actuator stem/gear same as above (2nd hand)

Sorry cant be more helpful. Others may

The sun load sensor is on top of the dash board on the left. It will report a fault if you have done the test in the shade.

The outside air temperature sensor is just behind the grill if I remember correctly. Disconnect it & measure its resistance. Should be a couple thousand ohms and decrease as it gets hotter.

Fix that and then worry about the pbr thing.

Mostly the door actuator sticks in place and just getting it to move is enough of a fix without replacing it.

Thanks guys. Will try to source the replacements of the sensors and I guess I have to get another actuator cos I broke the stem where the gears sit in and don't want further problems. I have manually moved the actuator so that I have my vents open now. So I do get the air from the blower. Well will try and get back to you guys.
