Blown fuse - again and again

[por986]

Hi,

2001 S 71K miles

I noticed that my windows stopped working and because it happend to both windows simultaneously, I figured it was the fuse - In looking, sure enough I found the primary fuse had blown. I replaced it, it worked for a day, and then blew again. Because I used the spare in the fuse box, I figured that with 10+ years on the clock that maybe I should use new ones. So I purchased new fuses, replaced it, and over a day it blew again.

When I replace the fuse, everything seems to be working fine.

Never had luck with working on elecrical systems, so I need some detailed advice on where to begin my troubleshooting. Where should I start, what should I measure, etc.? Any help is much appreciated.

Thank you in advance.

Did the replacement fuse blow after a day of NOT operating the windows at all, or did it blow after (or during) moving one of the windows up and down?

If it blew (or continues to blow when replaced again) only during or after operating one of the windows, you may have a loose wire that is getting caught and shorted against a section of the window when it moves up and down. If that is the case, you will have to remove the door panel to inspect the wiring, especially the connections leading to the electric motor on the window regulator.

You can also inspect the wiring harness between the door and the body for damaged wiring.

Thanks.

The window seems to operate throughout the day, and then I get to my home.in the evening. I roll it down to enter the gate code, roll it up and park - The window seems to drop/raise when I open the door to get out, otherwise the door wouldn't close properly. When I turn the car off, in the morning it is blown because I notice the door not opening - window not dropping.

I have heard a noise in the door when the drivers side window is operated so maybe that is the wiring getting caught on something - will take a look.

Until I track it down, I have been placing a fuse in, putting the top up or down (or using the windows), and then puling the fuse. Lather, Rinse, Repeat. :-\
