When i had my alarm fitted there was a clicking behind dash in-front of the passengers seat. This went on for about 2 weeks before suddenly a lot of smoke appear from the heater control unit. The clicking stopped at that point and ever since the control for the heater has been broken.
Part number is: 129 83004 85
Car: 129 - 300sl (1992)
A side effect is that the auxiliary fan in the engine bay turned on constantly. I am not sure if that was because the wiring through the heater control was no longer working and so the engine assuming the water temp was high.
Anyway attached is a picture of the fried unit. I am hoping that it was simply a loose connection and that replacing the unit will fix the problem.
1. can these be fixed? You can see in the picture where is has fried.
2. if not where can i get a replacement?
3. based on the info above do you think it is actually a problem with the unit?
Thanks in advance for you help.
