Hey all,

Just recently my aircon has been stuck on hot, and by hot i mean like it almost burns my face?? neone had this problem or know where to look to fix it? could it be some sort of fuse? or could the valve that lets the coolant run through the heater radiator be stuck open, and if so where abouts is it located??

common problem.

due to the climate control system.It has a brain???

If any sencors fail the air tends to go to extremes full hot/cold.

also if the it thinks the air conditioning has frozen,temp before and after evaporator..

the heat is controled by a blend door.the door has a electric servo motor on it.the door also operates a tap.so if the tap was full on the door would still close and you only get warm air,not 58 cel+.

the climate control works by heating the car then cooling it of.so if the cabin temp sencor thinks its cold,it just supper heats the car..

How do you get the Climate Control into Diagnositic mode to check out what is not working?

John, have you taken the dash panel off anytime recently?

On my R33 there is a thermometer next to a vent just left of the steering wheel. When I did my car stereo I disconnected it and forget to reconnect, and boy was it warm. It could also have come off, or gone faulty...maybe.

I know of this site for getting into diagnostics mode: http://www.overflow.250x.com/

under FAQ, electrical, Air Con...might be something there that can help
