I've got a 2001 ford explorer sport and the drivers power window only goes down a third of the way and then gets jammed, it looks like the window is being pulled down more in the front. how do i fix this?

well it can be all these causes
fuses blown , no other windows failing
the motor is bad, or its child proof clutch inside dead
the switch to turn it on is dead.(bad)
it is jammed. i pull door card
then see if guides are wreck of rust for 22 years, yes.
then pull the motor out and move the window by hand oops its jammed. cause is obvious , looking
a volt meter on motor pins shows 12vdc ,upbutton pushed
gets you to the motor bad/window jam point off failure
but yes some motors do short. so check voltage unplugged too.

This is a known issue on this model with windows not working at they should.

Check the relay.

..

make sure power windows lock out switch on driver side not on position, that will cause power windows not work or you have faulty power window relay.

check both

If the window goes down , you have power, you need to check the switch first then test the window motor for proper operation

check relay

If you can hear the window motor working ,the drive belt is probably broken ,that is to make the window go up or down .
If no sound ,the wire's in the door jam are probably broken ,you can test this by using a test light.
Also, check the electrical connection's on the window motor,and make sure they are not melted.

I have a 2003 chevy silverado and the passenger side power window does not lock or the window wont go down.

if it were a fuse it would effect all windows or you have a relay problem - the switch it self sounds as if it bad, check with a voltmeter

do all your other power windows work???? yes then it is the rear window switch or the power window motor... if all windows don't work then relay or fuse
