you know how to locate the wire colors now.

if these three are good, we will move on…I am really beginning to think the seat guy broke or cut a wire…or he pulled a pin from a connector.

back in post #64, I said… see above…bold and underlined.

your latest post has me convinced your seat guy screwed up your seat.
Not sure if you can get the seat guy to give you the money for a new to you, used seat but I would ask or just cut your loses and purchase the salvage yard seat…the other problem is the salvage yard seat has old leather.

I still think you can locate the possible cut wire or disconnected connector.

I think I may be on to something. I the first photo these two connectors lead to two of the motors but terminated at the back of the mechanism like he one in the second photo. I believe these to be limit switches. Is that correct

I gave up on trying to find what was keeping the seat from moving. I found a used seat and tested it prior to purchasing it. I moved the new leather skins over and all is back in the car and working.

I now have a passenger seat in Ecru to part out. All bits are for sale and the leather is a 6/10 with no rips or tears. 2 seat position controllers and position switches. Both proven to work on the new seat. I won’t sell the harness as I think there is something wrong somewhere in it. Let me know what you need and your zip code and I’ll give you a price.

now I am go into take a ride with my Sweetie.

Since u have nothing to lose, any interest in pulling out the harness and seeing if you can find the break? It seems like lots of stuff didn't work, so whatever the break is, it is a might powerful one.

My guess is a ground is bad, or maybe a two identical harness's got pulled in crisscrossed

Didn’t charge to move the covers between the seats. Also split the cost of the used one.
