Hi,
I know there are lots of threads about AC-heating problems,duo valves etc.None of them gives me answer for my problem.
Had a problem before with AC control panel all leds were coming on, only way to switch the unit off was to remove the fuse when car was off.After a while everything stopped to work - panel is on you can adjust temp, fan speed but nothing is working.I bought another unit but it is the same.
Any advise on this please.

Hi Borys,

Can you tell us what year the car is and specify the behaviour of the system in more detail.

Mike

It is a 1996 CL420.
At the moment with new control panel.When car started display of the unit seems in order I can adjust temp,fan speed manually put it to auto,etc - all switches, controls seems to be working ok.I just don't have a response from the fan at all.
Thanx
