Hi
I'm new to the forum and I hope somebody can help.
I have a problem with my 89 Coupe with electronic climate control.
No matter what setting I put on the controller I get very limited heat from the vents, I have used the diagnosic mode on the head unit and this indicated both the internal and external air temperature sensors were faulty, I have replaced both of these but it still blows cold what ever setting it is in.
I have confirmed that I am getting water flow in and out of the heater matrix and the matrix is not leaking.
The only remaining fault that is showing on the diagnosic is the potentiometer position is incorrect, I was wondering if it could be a vacuum fault, the controller was recently replaced with a new unit.
Any help would be greatly appreciated as it is starting to get a bit chilly here in Scotland
Thanks
