Okay been looking for leather replacement covers. Is there a difference between seats of the park ave and the ultra? 60/40 seats. upholster I talked to wasn't sure but thought there maybe, he has a different pattern then mine, glad he is trying to find out.. any wise words ?
It also seems there is a problem with raising and lowing drivers seat sounds like motor is running an not going anywhere, I am guessing there is a plastic gear somewhere that is broken? anyone have the steps to get to the gears?
any help in finding where seat parts and seat covers can be found? would prefer newer parts then bone yard.

I'm not sure if the seats are different, but I do know where you can order the seat covers, and other stuff online, check this out.

Part #20 should be your seat covers, they are $182.00.
You can look at the exploded diagram of the seat here, I'm not sure if that will help you with getting the gears fixed for Part #12 the ACTUATOR. Front Seat Adjuster - VERT(FRT VERT)(W/FRT VERT POTENTIOMETER) if you have to buy that new you are going to pay almost 400.00

Hopefully somebody is better able to help you soon, wish I could have been more helpful.

Thanks Will.
I haven't been able to find any covers or any one with a pattern for the leather seats in the 97 Ultra that I have.
leatherseats dot.com has the base model seat covers but not one for ultra, good guys there helping me not order the wrong ones.
Now with this link it show the foam cushions found on the base model, and shows the same cover that leatherseats has, this link you left has a green one I need gray,182 would be a nice price It will cost considerably more then that for the good ones.GM has discontinued parts as fast as it can for these models and yrs, and not enough of them to keep us in parts from venders.
I am wondering if I got seats out of a base model I could change the foam out of a base model to the ultra model, if changing that and finding a way to keep the heated part. if I could then use the new base covers? Wouldn't match the rears but I can't find the ones I need. an who would notice.
Hope the donor has seat parts that are good too.lol might just buy a base model for a donor car might be cheaper then one part at a time.lol
