power seat not working

[jimb317]

I have a 2000 GMC Jimmy. the drivers power seat is not working. the lumbar works fine. I have power at the switch. but I can't figure out what is wrong. Is there a relay for each motor? Is there an easy way to fix this?

I believe there is a 20A fuse in the vehicle and a 50A under the hood. Make sure you check both places.

I can't go in reverse. It worked fine earlier now Noway No how. When driving it runns rough and in the high rpms. Transmission? Please advise.

Grease the track and check for obstructions and jamming.

I had the same problem with my 2000 LT Chevy blazer. It turned out to be under the back seat under the carpet. The wires were corroded.

under the back seat?

[hamlinhazel]

Yes, it was under the back seat. The whole back seat had to come out! GM needs to come up with a better plan for all of these power cables! Running them on the floor is not a good idea!

How does wiring under the back seat have anything to do with the power seats in the front.

from other forums found that Orange wire from 6 pin connector under seat had power - traced good continuity and power to lumbar switch but no power at seat 8 position switch - for grins ran jumper from orange wire on lumbar switch to orange wire on 8 position seat switch and seat became fully functional - so spliced in jumper between both orange wires and wallah ! the electric seat that didnt work for years is now working again.

Just thought I'd post a diagram, 6-way power seat circuit. Click on the link. Everybody have a good day.
