I have a 1990 iroc convertible and I went for a drive tonight and the dash lights went out and the driving lights. When I replace the fuse for (20 stop lamp) it blows imediately when I turn on the lights. Also I have no parking lights? Anyone know what or where to look? Everything works except the parking lights, dash lights and fog lamps? I do have head lights and brakelights? Could this be a stereo issue? I have an aftermarket stereo with amps and subs, but all of that is still working?

(There is a wire that controls the brightness of the radio, could it be touching metal and causing this?) After all this is aftermarket equipment. I just got the car and might have answered my own question. Please add comments if you have seen this before.

 

Ok update, it is not in the stereo. Just pulled it and no problems.

 

sounds like the switch is going bad 20 for a new switch should be good.

 

I thought so also, new switch installed and still blowing fuses! The car is at a shop getting the non-working alarm removed and then go from there? I traced everything and found nothing?

 

gotta check the grounds on that circut.. could be a loose one causeing it to short and blowing the fuse

 

Found the problem!! It was a corroded light socket. The left front turn signal socket was corroded and shorting out. Cleaned it and voala. fixed.
