Title: Question about late model GM power seats
Post by: Stevie G on October 24, 2015, 01:04:07 PM

Hey there gang,
Been quiet for a while I know.
I need help with a pair of seats I'm installing in my tow rig. Pulled seats out of a late model Buick Lucerne. We tested them before pulling them and they worked fine. got them home and ready to install, ran jumper wires for power, and the passengers side works like a champ, but the Drivers side is dead. I'm hoping someone here as found a solution and can help. They are six way seats with front tilt, back tilt, fwd/rev, and the four way lumbar button.(?)

Options I can imagine are:

Bypass the black box under the seat and wire the motors straight through the switches

Replace drivers side black box with same model passengers black box

Somebody here knows a wiring hack to make the existing controller work

Any help or ideas are greatly appreciated. :?:

Maybe they only work if you're sitting in them. Or they could have some inter-lock with the seat belt or air bag circuits. Did you ask what year the Buick was? Wiring may be different by year. Just ideas. I'm sure every one is busy looking at the pictures. GPster

You didn't say, but was there a memory function button, (usually on the driver's door panel), on the Buick? If "yes", closely compare the driver's seat wiring to the passenger seat wiring; if an extra pair of wires is found on the driver's seat, try to temporarily jumper the pair to bypass the memory circuit.

Additionally, & better yet, do an internet search for the seat(s) wiring diagram(s) to verify the driver/passenger seat wiring variances. I'll also look to see what I may find......

Thank you for the link.

GPster, anything in particular you would like a picture of?

There are 25 wires for the drivers seat which is out on the bench. The passengers seat is in the truck at the shop. So I guess I will tackle this again next weekend.

I was talking about the pictures that Carps took. They have been at the top of the page for days and everyone is looking rather than doing anything else. GPster
