Air con temperature

Contrary to most problems I am wondering whether I have an issue with my air-con. Now that it is getting a bit colder I have the temperature set on Auto to about 24C. It gets up to temperature and the cabing is nice and warm and then it starts blowing cold air into the cabin.

I can understand that it is trying to regulate the temperature but it tries a bit too hard and the temperature drops too far. Is this just a feature of the 166 system or something that needs adjusting?

Any suggestions would be much appreciated.

Re: Air con temperature

Try checking the small fan that draws cabin air over the sensor. If the fan has stopped the sensor will misread. Could be covered in dust etc.

Re: Air con temperature

does this have a self test feature like on my 1990 164? (returns error codes showing things like short and broken circuits)

Re: Air con temperature

Is the fan behind the perforated panel to the left of the steering wheel?

Re: Air con temperature

Yes that's the internal sensor. Checked mine the other week and it was pretty full of fluff.

It didn't fix my problem but it's worth checking yours to see if there's an improvement.
