When I bought my car recently the power seats worked perfectly, the air parts and the electric parts. Now the lumbars have quit, but the travel still works fine. That rules out the fuse, right? Anyone got a quick awnser for me?

Check the compressor under the passenger seat if all your lumbar functions are out.

Bench test it by giving it 12 volts. Also check for 12 volts at the connector when selecting a lumbar function.

nevermind, fixed it. thanks for the suggestion though.

apparantly when I was vacuuming under the seats in the dark at the carwash I snagged the harness and caused the compressor plug to come unplugged. everything works fine now.
