Will not adjust forward/back.
Why it took all evening to pull it out of the car is another story.
I have the 2nd row out for different reason. Now I have a single seat wagon (except for the tail-gunner)
until I get time to figure out this puzzle.




Anyone been down this road? I'm welcoming suggestions!

Test light on the harness for the seat coming out of the carpet
Power?
Yes! = bad motor on seat
No? = bad switch/broken circuit

I assume (yeah, I know, let's say "tentatively observe") that it gets power because the motor jumps when I hit the switch.  Could still be a bad/stuck motor, or a short which is not completely broken.
But it seems like a good motor trying to push something that will not move.

I read on another forum (before I had this problem - can't find it now, of course) that those jack-screws can get jacked up, but these look pretty clean and straight.  
I also have yet to figure out what parts slide, and see if they are stuck.

A light would be a non-invasive test before I start taking things apart, so thanks for the suggestion.

I guess, since there are 4 motors, swapping things around to test a known good would be a next step.

If/When I start taking things apart, it'll be feeling my way around, learning as I go, and hoping I can get it all back together again,
which is why I'm hoping someone with experience can give guidance, before I make too big a mess.

Swapped to good motor. Negative result.
Something in the mechanism is stuck.
Doubt I'll have time to mess with it tomorrow.
Certainly not before the JY closes, so I hope I don't need replacement parts.

If I make it down Sunday, it'll probably be with the seat thrown in the back.

RESET --

I stopped by the JY this morning. Both wagons in the yard have different controls than mine. Caused me to re-evaluate.

What is stuck on mine is a power recline, which the ones in the yard. and my driver seat, do not have.

That explains why suggestions to fix/replace the rack weren't working out: the recline is not in the rack.

It still isn't fixed, but I'm closer to solving the puzzle.
Or I could just grab a rack with a manual recline, swap them out and be done with it (but what fun would that be: Half the joy of a Buick are the unnecessary accessories).

Figured I'd wrap this up.
My mistake confusing the mechanisms. When I figured out the malfunction was in the power recline, and the power recline was in the seat itself, not in the rails, and oprates independently, it was solvable.

The power recline is operated by two jack-screws on either side of the seat frame.
The gearboxes on the jack-screws were stuck: rust or dirt or 20 years of dust bunnies stuck in the grease.

Lots of WD 40 and patience, jogging the mechanism with one side attached at a time. The motor would heat up and stop, so I jogged it until it stopped, went and did something else for a while and came back to it.

Eventually the side most stuck moved just a bit, so I knew I was on the right track.

That's where I left it, so I could drive to the "Mod Day" (with just one seat).

Came back to it a few days later and it moved more easily. Good ol' WD had done it's job on the gearbox, so I used picks and Q-tips and degreaser to clean the threads on the screws.

While the seat was out I did some cleaning on the underside, sanded the surface rust and carpet fuzz off the attachment "feet," and applied a couple of coats of rust reformer to them.

You can see what I'm talking about in the pictures above, if you can see the pictures. I can see them when accessing the Forum with Google Chrome, but not Explorer. I don't understand that, but I'd rather spend my limited grey matter understanding my car than understanding the Internet.

BTW, Thanks to Tom, Fred, and Indy for the suggestions and the counseling along the way. Sometimes just having someone to talk it through can be helpful.

Glad you figured it out.

Thanks for wrapping it up, nothing I hate more than searching the Internet, finding an identical issue, and never finding a solution because the OP never concluded

Thanks guys. I share your pet peeve. I have used forums as reference material.
Had this been a unique "Mod," or something to make the car more powerful or cool, it might have been more interesting; but sometimes it is these pissy maintenance issues for which help is harder to find.
