Temp sensor / aircon ECU
i have a problem with my 2002 156 2.0 jts.
I had the aircon re-charged by Kwik-fit on Saturday, and all seemed fine.
on Tuesday, the car had it's break fluid changed by a local garage (non-alfa).
When my mrs picked up the car, it was registering -45 c and air-con does not work.
We took it back to the garage, who have replaced the temp sensor in the wing mirror, and the fault is still there. The garage spoke to Monza sport, who seem to think it is the aircon ECU / control panel - has anyone else had this problem / can thorw some light on it for me?
How expensive is the aircon ECU / control panel?
Thanks in advance for your help.
