Hey all, this is my first post. I recently bough a used Volvo 940 from 1992. It was a really great deal. However, the car has some problems and I was wondering if somebody can give me a clue how to fix them or what might cause them.

1) Cruise control doesn't work at all. What might cause that? How can I find out where the problem is?

2) The passenger's seat heater doesn't work. The button's light doesn't work either. Could it come from the button only? How can detect the problem?

3) Sunroof doesn't work. I don't hear the motor working at all. But I also read here that the button often causes problems. How can I find where the cause is?

Other than that the car is excellent. I just love it and want to make it perfect.
