i have a 2000 acura tl my rifgt rar window keeps blowing the 20 amp fuse located in the passenger front fuse panel any ideas what could be causing this? anyone have the same problem ?

 

Yes, one morning there was some light snow on the windshield. I had left the wipers set to intermitent, and I started the engine while the driver's door was still open.
The wipers fired up and dumped snow all over the inside of the driver's door and the snow was packed in around all the window switches. I cleaned out all I could, but some water got into the window switches anyway.

Whenever I hit the left rear window switch, a 20 amp fuse in the passenger side panel would blow. It would disable all 4 windows and the sunroof, even though the fuse was labeled as only being for the one window. I sprayed WD-40 down around the switches. It blew a fuse a time or two more, but finally quit it doing it before i had to take the door panel off and really clean the switches.

 

You didn't mention whether trying to raise/lower the window does anything before the fuse blows; does the motor run at all?

If not, then the transmission is frozen or the motor is seized.
