2000 GMC Jimmy Power seat stopped working

Check in the under hood fuse block or power distribution center for fuse #72 and #75 these are 60 amp fuses. If the problem isn't there you have Two separate problems, check at the switches for battery voltage and ground. The most common problem is switches.

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.

there is a 25 amp circuit breaker for seats.should be marked POWER SEATS in the fuse block. the ORANGE wire at the switch gets power from that breaker, so check the ORANGE wire for power.

IF THE LUMBAR IS WORKING, THE POWER IS THERE . IF EVERYTHING IS PLUGGED IN UNDER THE SEAT, THE SEAT MOTOR MAY BE FAULTY

bad switch?

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 had the problem with the front seat not working also. It was the connector under the drivers seat that was loose.

I have ur aswere for the blinkers. u have to change the breakers under the stereo where the outputs are. there are to gra things

check the wires behind the seat control on the side if the seat, sometimes the wires will get pinched and short to ground

I have a 1995 Jimmy and the power seats didn't work. I put my own power wire with a fuse between the seat and the live wire under dash. It works fine.
