you have to disassemble the compressor and free up the gunk that is in there, I have done this a few times now and it takes about 20 min to complete

SO that is the compressor right ( i would assume so)

What do I need to take it apart?

Any pics or could you give me some idea on how to do it?

Default 98 AL7 Wiring Schematic

Cant figure out why my compressors not kicking on,

It runs fine, (tested it off the seats) but wont move the lumbar at all, or even turn on.

It seems that I have a wire just hanign out on the seat, it has a white plug and has orange, pink, blue wires on it. where does it go?

Theres no spot for it, did I leave part of the harness in the donor car?

BTW this going into a 92 caprice wagon

Sorry, no new thread is needed to continue the same discussion. That tends to confuse the folks trying to help you as the two threads take similar paths to the same fixed end result.

If you have any connectors w/o the other side, you are missing part of the harness or a module.

Are you 100% sure, I pulled the seats out the car myself, and test ran them before doing a install. Theres no other spots or connections to go anywhere. IDK if its a wire that needed to be ran back to the seat, because I didnt notice it until I took the compressor out.

A schematic of the diagram would help me.



BTW 13 second bonnie I love to see cars that are not supposed to be fast get down.

I'm positive. Done a couple swaps with these seats myself. When I finish pruning the wiring etc from the car there'* three things to hook up.

Power
Ground
Illumination to the switches

All connectors have a home and all get connected.

13 second is actually more like a 12 second car with a poor driver.

I can post schematics tonight when I'm home. If you need ti sooner try searching, it'* probably on the site somewhere.

Got a pic of the connector on the passenger seat that is empty? Both should be connected though. IIRC there'* two passenger and three on the driver side, three to the switches.
