Have a 1998 olds regency..bad interior..potential donor car is a 1996 olds 88...are these seats compatable as far as bolt up and electric connectors?

you change it from under the car

Google "used oldsmobile parts", that will take you to vendors who take them apart and sell the parts off one by one. You may have a large auto recycler close by and i would start by searching their website, often you can search their inventory on line. I live in appalachia and we have two local junkyards with web searchable inventories so this service should be everywhere in civilized US. plus a search will show you how many other GM power seats will fit that year and model. You are going to want a used seat, and you do not want to ship it, there are no new seats and to repair an old seat is not feasible as there are no parts and would cost far more than a serviceable used one. you want the newest, and lowest mileage donor vehicle you can find. the electric motor in that seat, and in all other seats, is going to die eventually from use and age, just like the whole car. if possible i would find a manual seat, just bolt it in the same mounting holes and live with it as a replacement power seat is going to die eventually also. you may have to get seat covers to make them all match.

Clean the battery connectors to the battery and replace bolts.

seat motor is going bad?

It depends on how bad everything is, you could need new foam, seat material, headliner, door panels, carpet, etc. It coulkd cost anywhere from $500- $1000 dollars. Your best bet would be to find a Donor Car at a Salvage yard and take out what you need.

I do believe that from 95 to 99 are direct fit replacement seats. The seats may vary in options but should bolt right in. Good luck and have a great day.

It's located deep in the valley! Under the "LOWER intake manifold". copy and paste this link in your browser, or try clicking on it. It may be helpful to you.

I didn't find this link until after I had already disassembled my truck. This is the hardest job that I've taken on thus far, hope I can put it all back together properly. I changed the gaskets on the valve covers since I had everything off.
To answer your question: It's under your lower intake manifold, so it's a hard job!

simple, remove the headrest,move the seat forward fully remove the bolts 15 or 18 mm heads that hold the rear of the seat track move the seat rearward remove the final 2 bolts holding the seat set the seat as far forward as possible and remove the seat after unplugging any electrical connectors of corse

There is a fuse and or a relay you need to be looking for. Also for the fuse to be blown something has had to have shorted out. It could have been water causing the short or you have a bad wire somewhere grounding out.
