I have a problem with my radio. It normally does not even turn on but randomly comes on when it wants to. When it does come on you are not able to control anything. The whole screen goes blank when it is off.

The other question I have it that I just put in a blower motor resister switch not even 2 weeks ago and it went out again. Any ideas as to why this keeps happening?

 

sounds like maybe a grounding problem?
