Anyone got any wiring diagrams for an ST195 caldina heater circuit? The missus car has been playing up forever, the on/off 1.2.3.4 control for her air con doesnt work properly. Wont turn on, sometimes turns on by itself at random times. Wiggling the selector up and down makes it go on and off too. I finally grabbed another whole unit from a wrecker, and it does exactly the same thing!
I'm thinking either the unit from wrecker is dodgy too, or there is a bad earth somewhere and wiggling the on/off lever causing it to earth through the circuit there somehow, turning on/off whatever it feels like?
Highly fustrating, esp not being able to get demister to work in winter!
One of these is what we have, for auto:
