R33 Climate Control Issue

[driftin_out]

hey my climate control in my r33 hot and cold adjustment doesnt seem to be working anymore... :|

it did use to work.. lol

it seem to blowing hot air all the time even when set to 18 degrees

it still blows hot air with a/c on and with changing the fan speed.

any ideas were to start?

hose has come off behind the dash or the plug fell out. To the left of the steering where theres a little vent on the dash, theres rubber hose that connects to it and a small plug with a resitor in the end of it. The AC uses this to work out what tempreature it is inside the cabin. without it it just defaults to full hot.

Pull your dash out and check that there both pluged in.

I had this exact issue once when I pulled my dash out and forgot to plug the sensor back in... full hot all the time

[driftin_out]

but i havent touch or pulled anythin out of the dash....

so i dont c how it came out or undone..

i noticed last nite, i turn it the air on straight away..and set it to 18 degree,

and even after my temperature went to normal,

and i adjust the the temp to 32 degrees it felt lik 18 degree still...

so i actually think that the hot/cold buttons...

well what that goes to is jamming and is not working properly....

is ther a servo/motor that i can check out, and if so wer is it? lol

bumb...

i found this...of another topic..

"Given you just had work done done on the car I'd say the ambient sensor is unpluged ( it should be the little black lump next to the horns, behind front bumper).

Like GTScotT said its a common thing, mechanic forgets sensor, A/C thinks the outside temp is -40C or something and fires up the heater 4 ya

There are 2 other sensors, one at the back of the dash ,left side (sunLoad) and one just to the left of the steering columb (interior temp).

Any of these left unpluged/faulty will screw up ya AirCon (usually with the heat your gettn) "

"have a search on SAU for heater threads you should find plenty of info on the heater. being a 33 owner I'm not familiar with the 34 BUT if ya stick ya head under the glove box and hit the 'recircualte air' button, you should see a 'rod and lever' arangement mo0ving, thats the cowl door. Same goes 4 the heater cores tap, change the temp and something will move to direct the water flow.

like I said though do a search. I'm sure I've seen full removal guides and all. "

did you look at the ambient air temp sensor? or the cabin air temp sensor?

Check these, doesnt matter if you havent been doing anything to those areas, things happen, wires come loose or go bad. Just check.

Search for Air-Con diagnostic mode. Its on here some where but im lazy to find it. You hold down a button when you turn the ignition on and you can see which sensors etc arnt working

Otherwise check the hot/cold blend servo to see if its stuck or broken.
