Question about 1999 Cadillac DeVille
The drivers seat does not work. A mechanic hot wired the truck and fuel door in the glove compartment.
That was a butcher-- not a mechanic
Get a factory wiring diagram & straighten the
wiring out, as the vehicle was built
On that diagram you can see everything on the vehicle
in the electrical system,no one can tell you what is were
or how to diagnose & fix problems,need to see them on paper

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

No fuse.These seats are protected with relays and a seat module.The module is under the drivers seat.There are 3 connectors and it would be hard to check all these wires for power to the motors.First look under the seat and make sure none of the connectors came apart under the seat by something that might have been left or rolled under it.The 2 main ones you can check are the connector 2 terminal C and connector 3 terminal A.C is a black wire which is ground and A is a red wire which is the feed power wire.Connector 2 is green and 3 is black.If the ground and power wires are good then you could have a bad drivers seat module.What I would do is go to the salvage yard and find a used module to try.Good luck.

Unfortunetly Cadillac does not have an access panel for fuel pump access until the newer years. You will need to drop the tank. Also, don't let the tank come slamming to the ground, make sure you take it slow so you dont dammage the lines to the sending unit.
