Seat was working fine, used the lumbar control and power seat controls quit working. Looked for fuse, could not find it listed in diagram? If not fuse any suggestions
Fuse for drivers seat power switch controls? on 2006 Cadillac DTS
If you can't find a fuse (look in the owner's manual), check the connector under the seat. Also check to see if the control switch's connector is loose.

the ddriver's door control module is in the fusebox under the back seat(there's another fuse box under the hood) You can unplug the module and take it to an auto parts store to be tested
