I know I know I probably asked this many times, but. Will a failed Seat control module not make none of the seats functions work but the Lumbar Support? Mind you even the memory function won't move the seat forward or back, nothing moves the seat at ALL. Only thing functioning is the Lumbar.

 

Lumbar is a separate function even though its part of the assembly.

Check with Dave here, he has a couple seat drive motors (fore and aft....and rise and fall w/memory) the last I looked and don't be afraid to ask him about any part you don't see....very good service. He has a lot of New Old stock...some used.

+1 excellent resource, especially for NC & SC.

 

took the module out and the lumbar still works, i doubt it is connected to the seat module.
