My heater/air-con comes on full blast every time the engine is on. Can't seem to turn it off. The circular switch doesn't seem to work. Both heater and air con are certainly working, the car is as warm as toast or cool as ice, but I can' t seem to get them to stop!! Any ideas?
I would think that the electronic fan speed regulator is faulty.It is part of the blower motor unit but can be replaced as a seperate part.It is located behihd dash and access from pass side footwell.Part cost about £80 from Citroen/Peugeot.hth
This is possibly the same as the control unit fitted to the Xantia, whereby fan speed is controlled by power transistors. If it is, and you're handy with the soldering iron, you can replace the transistors.
I had this problem on my Xsara (2002 Hdi). The speed regulator module inside the fan unit was faulty. Don?t bother trying to repair?I couldn?t identify the devices fitted, despite research. The main dealer charged £45.00 plus Vat for the part. Fan control has been fine since. It's not too difficult to replace, given care.
hi i have a berlingo hdi air con with a blower problem, it just stays on all the time. i have priced speed controller and is about £88 and you have managed to get it a little cheaper about £45, can you tell me where please?
