80 Sedan DeVille: Where to get P/Seat motor repaired or replaced?

New to the forum, but I have been in the site on numerous occasions. Anyways, my elderly mom called last night to say her driver's power seat in her '80 Sedan DeVille has stopped working. She rarely drives anymore and has another car, so, it may be a few days before I can look into it.

Assuming the worst and that's it's not a disconnect, fuse, etc., is there a member or vendor that repairs the motors / drive assemblies and/or has some good used ones? I don't have the seat code, but I believe it's a 60/40 non-memory cloth seat.

Thanks and take care. Dave

You probably know this already but: Some things to look at before condemning the motor. First place is to look for melted plastic connectors. Sometimes the connector's spade terminals heat up and the plastic starts to melt allowing the spade to move away from it's correct spot. Many of these will look OK until removed and inspected carefully. Also could be a broken power feed wire in the door. Relays are used on some but not all options. Sometimes the relay will have melted plastic allowing the contact to move out of place. These can usually be opened for inspection. They are usually located under the seat. Of course, you have the switch itself. There are several different seat options as you already know. A schematic will be necessary if the visual check shows nothing. You can jump power right to the unplugged motor but depending on the transmission, it might not move anything.

Got a chance for a brief look this afternoon. 60/40 split bench, cloth, no memory. Switch and motor itself are working fine. The plastic around the motor's gear got hard and brittle after years in hot Texas and broke apart.

Anyone know where to get another, or parts to convert to a manual seat, or who has repair parts? Looks like some pieces might be missing as my elderly mom "remembered" possibly sucking something up in the vacuum while doing her car right after the seat died the other day. Take care. Dave
