2000 GMC Jimmy SLE driver's power window

Hello-
If your fuses are good, perhaps your heated seat switch is faulty. You can test the switch for connectivity using a meter to see if power is going through the switch when in the ON position. If the meter shows no power while in the ON position, replace the switch. If power is reaching the seat, then likely the heating element itself within the seat is the culprit.

with key on door open, hold switch in down position and rap door panel with rubber mallet...if it works, need motor, if not, check switch for power

check for broken wire inside boot at door jam

Inspect or replace the window lock and unlock switch on the drivers door power window switch. There is a lock and unlock switch that will disable the switches to the other power window in the Jimmy. Check to make sure that switch is in the unlock position to have the other power window switch to work.
Thank you for suing fixya and good luck.

Possibly a bad switch. Is this for the passenger window or the driver's window?

if the drivers side switch is the only one that doesnt work it needs replaced confirm by making sure the passenger door switch works the passenger window

Left side of the dash, to the right of the IP fuse block. Its a 25 amp circuit breaker, an aluminum cased breaker. CHECK FOR POWER ON THE SEAT SWITCH "A" TERMINAL AND GROUND ON THE "D" TERMINAL. IF YOU HAVE POWER AND GROUND THE SWITCH IS BAD.

I work on these all the time, Your switch is bad Drivers door, go pick one up at a wrecking yard is the cheapest way, We do this daily, Or go to car-parts.com and order it

The same thing happened to my 1999 JMC Jimmy recently. I believe the problem is that your power window motor has most likely gone out or is starting to go out. The motor will need replaced. They are pretty expensive new. I went to a junkyard and got one for around 15 dollars. When mine went bad, I had rolled my window down about three or four inches and it stuck there. I took my door panel off and tapped on the motor while holding up on the window switch and got it to go up after a few minutes. I am replacing my motor today, I'll leave an update here about the outcome when I finish the job. I hope this information helps you.
