1999 Ford F-150 Electrical Problems

Have you checked for a bad ground?

I asked a question yesterday in why am I blowing fuses sometimes when I use my power windows and the fuse that blows is a 30 amp under the hood. You replyed by asking me to check for a bad ground wire. So now my question is where is the ground wire located at and what to look for when I locate it? If it is not a bad ground wire then what could be making the fuse blow under the hood sometimes when I use my power windows?

Remove the door panel and you will find the wiring going to the switches. check for broken or skinned wiring. As far as other things, a common place for a short to exist is between the door and door frame. There is a rubber boot covering the wiring and things break under there. Finally, the motor could be drawing too many amps due to an internal short.
