R33 Ac

[Ultimategtr]

Hey all, so iv read the R32 ac thread here, i have a very similar issue

when i turn the temp up to anything over 18-19degrees, it just blows HOT air. Its like i cant get semi warm/cool air, its either HOT or COLD air.

Any ideas? cars an R33 25t. The AC works sweet, its just that it blows COLD OR HOT, NOT semi cool/warm..

THanks

Same here just checked it today!

lol maybe theres nothing wrong with it if we all have it.. Could just be povo a/c in the car..

Does anyone not have the problem lol?

this should only happen when the air temp sensor behind the dash is unplugged or broken.

mines removed atm, so it does the same thing, hot until you put it to 18 deg.

do a search to check for error codes on the aircon, im sure there is a walkthrough that could confirm this for you.

error codes are a good start, do you get a klunk noise when you turn ac on, if so your mixer door mighten be moving enough to get a change in temp for oyu

check the little plug near the vent by the clock. as craved said

I havn't used mine for about a year and now ts just pushing hot air aswell. Had my dash off a few times this year so ill check that air temp sensor and see if it solves it.

Hey thanks for your replies.

Alright i think i know which sensor youre talking about. Ill have a look at it tomorw after work. Come to think of it, my ac makes that klunk sound everytime i turn the AC on.

Alright i just ran the diagnostic. For the ones above who dont know how to, heres the link. Soo easy.

22 - Inside air sensor

if that came up - then its either broken or unplugged

never worked out what the sunload sensor does

[Ultimategtr]

wher the helll is the inside air sensor?

[PM-R33]

Where your windscreen wiper stalk is next to your steering wheel, right behind it on the dash you will notice a little vent thing. Pull your dash apart and its behind that. Will have a plug going into it, could be unplugged.

All fixed!!!! took out the front of the dash console and had a look at the sensor, 1 of the pins was bent and wasnt in. straightened it and plugged it properly.. oh and i cleaned it out too.. washed it out.. now it works sweet!!

cheers guys
