No power at the seat switch, 20 amp fuse in the fuse block is good.........anyone know if there is a relay involved ? Does the power actually come from the control module and not directly from the fuse block.......I'm thinking that the seat switch is just sending a signal to the CM......and then juice is sent to seat mattes.

 

Relays only require low current to activate, so you wouldn't need a 20 amp circuit to trip one, so my guess is there isn't one, (unless the relay is between the switch and the 20 amp fuse).

 

There is a fuse just for the switch. Check this I think it is #53. My seats did not work and saw that the switch had its own fuse. Replaced it and no problems since.
