Had an issue for a while where my climate control unit would not not show any lights, the buttons wouldn’t work, obviously the aircon and heating didn’t work. The only thing that showed on the unit was the clock which constantly counts up and repeats constantly when powered on.
I have taken it to an auto elec who had a look and he bought in a car aircon mechanic/specialist to check it out. Neither of them found any issues with fuses or the system itself. Also took the unit to another auto elec/electrician who took it apart and tested it all and it worked fine. The lights lit up and all.
so far I’ve double checked all the fuses, which are all good. The unit itself has been tested and works (however not when plugged into my car). No idea how to go about this/fix it. Any advice/tips/people to contact would be great thanks!
