I’m currently dealing with a very strange electrical circuit dropout issue. Here is the behavior. The car will randomly lose both the radio/cigarette lighter circuit and the windshield wiper circuit at the same time – never separate. Here are some observations that go with the circuit drops:

• No fuses blow
• Seems to happen more frequently when the car is really hot – as in summertime but it does happen in winter – just not as often.
• When I turn off the car and start back up, the circuits sometimes come back on but not all the time.
• Occasionally the push of a climate control button will coincidentally have the circuits come back up but again not all the time.
• I do have a Kenwood cd player installed in place of the original radio. Didn’t have any problems after it was installed just down the road. It’s not a very powerful radio so I don’t think it’s pulling a lot of power.
• In the fusebox, I do see that these circuits #4 – radio and #6 wiper are side by side and connected in the fuse box by a metal strip. I notice that other circuits are grouped similarly.
• At this point, I don’t have a circuit diagram but will be looking for a good source.

Would a good start be to just clean all the contacts and replace the fuses on both? I wouldn’t think losing one fuse should shut down both circuits but who knows. I have read that these fuses can be culprits even if they look fine.

We always hope that someone will read this and say – yep had the same problem and it is x. Not sure this will be that simple but anyway – here is a start. In searching, I really didn’t see anything very close to this issue.

Thanks!
Gib
