yes there is a relay switch in engine compartment or under dash

There is not a fuse listed for heated seats but fuse 16 is for heated mirrors and fuse 11 is power seats. i'm guessing one of those should also control the heated seats.

A couple of things to add to tinyp's solution. For Buicks, the regulator is bolted in, not riveted, which makes removal easier. Also, you'd better get used to this, as I have replaced 3 out of 4 window regulators on my 2002 LeSabre.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls
