You can find the problem if you have the circuit wiring and operating description , a volt/ohmmeter and lots of patience. First question , to clarify a little- with everything shut off , does the fuse blow as soon as it touches the contacts or do you have to turn on the key and then ??????????get my drift? Narrow down specific condition under which the fuse blows , and keep narrowing......and maybe have lots of the CORRECT amperage fuse handy!
Thank you. I don't think that it blows as soon as I put it in. I think it is when I turn the key because there is no reaction when I plug in the fuse. I put a new fuse in and tried to turn on the windshield wipers and fuse blows. Yeah. I know what you mean, I'll need lot's of fuses! I know that that particular fuse is connected with the windshield wipers, reverse lights and headlight adjustment. Thanks for the advice. I'll look for the circuit wiring and operating description. Hopefully I'll nail it down before the rainy season ; )
Maybe start by unplugging the wiper motor , maybe the place that said it was the wiper motor was on to something.
I wan't to do it myself. I am a starving student. Wiper motor is fine. I drove around with the front fog lamps on and didn't realize it. I think that is when something grounded/shorted out. I need to know how to find it.
When I did bring it to shop they told me it was my wiper motor. It wasn't! I don't have $100's $ to spend. They wanted to replace the wiper motor for over $300. when that was not even the problem!

Mine is doing the same thing. Did some research on net about problem, seems the reverse switch in the console is the culprit. Must short out to ground somehow.
