I disconnected my battery and installed a new Magnaflow exhaust. When I hooked the battery back up, my driver's side power seat no longer works. I have checked the fuse and it appears fine. I also swapped it out with another fuse, butit still did not work. Any thoughts?

 

The Driver's side switch actually has 2 fuses to it.

F3 7.5 A and F109 30A

The set is a memory seat, and different then the passenger's seat.

The passenger's seat, the switch operates the motors directly.

The Driver's seat the switch signals the driver's seat module ( F3 ), and the driver's seat module operates the motors ( F109 ).

So if either fuse is out, the seat will not move.

Take a look at F3, check both sides of the fuse with a meter or test light, on the exposed end pins.



Let us know what you find.

 

Thanks, I'll check on the second fuse today.

 

Both fuses are fine. I replaced them anyway, but the seat still does not function. Any other thoughts?

 

Time to check for power at the driver's seat module.

There are 3 connectors on the Driver's seat module.
C341A is a 24 pin ( 2 rows of 12 ) gray connector
C341B is a 2 pin Gray connector
C341C is a 10 pin ( 2 rows of 5 ) gray connector.

you are looking for the 2 pin connector

The wires are
pin 1 - Dark Green = circuit from F109
pin 2 - black = Ground

The other is the C341C connector
Pin 1 Orange w/ light green stripe wire = circuit from F3

Use pin #2 as ground and test for + DC V on both connectors.

These are hot at all times, so key position is not important.
