power windows died

ok, i have an 84 buick LeSabre for a daily driver.....


the windows were working fine one day and i took the passenger side front door panel off to recover it and the windows just suddenly quit working........

if you hold down the window button and turn the ignition key, the window will try to go down, but then it quits and if you keep holding the switch and then feel of the curcuit breaker in the fuse panel it will burn you its so hot.....

what could the problem be?

sounds to me like you aggravated a future short or broken wire isolate it by looking in the pinch points then by un plugging stuff you might have to use a short finder if you cant physically see it
most likey where you were working

Power Windows

Doc here,

Pull that side off again, It sounds like you may have a stuck or frozen window regulator, or insulation matting stuck in the gears..

Inspect the window frame and window to insure that the window is sitting square in the glass gaskets, and that those aren't dried cracked and hanging up free movement of the window.put a TINY bit of ATF on them to insure they will allow the window to slide..make sure the window doesn't have too much slop in the frame allowing it to cant and lockup.

Inspect the window regulator, look for stuff caught in the gears and put in some new grease..manually raise and lower the window by using the input shaft of the motor to be sure the motor can overcome any drag.

Measure the resistance to ground From your motor case to the main body (Not the Door) Be sure it is 000 ohms at R x 1 ohms...any more, than add a shielded / Braided ground strap from the Door to the door post. be sure you burnish the paint to bare metal and use a star washer at each, and test to be sure that opening and closing of the door won't cut the wire, and it will fold up nicely..

Lastly, check the switch itself, the switch case frame may have separated a bit causing it not to make good connection in a fully on position..If this is the case..you CAN try to re-crimp the frame, but you will probably end up having to replace the switch anyway..(it's falling apart mechanically)

The Fact that the Circuit breaker is heating up, shows that the circuit is "Whole" but overdrawing the specified current amount..the clue here, stuck motor, or window regulator..(I.E. Rotor lock)

Doc

Also check the condition of the connection to the motor. My passenger side connector is not so good but seems to work after I made sure all the parts that touch, touch really well.

then it might be the power supply or the ground .
find the power source and follow it to the switch and then the motors
might be a circuit breaker or lack of power to the whole system

use your test light and reverse the polarity to check for ground
