: LMM heated seat switch/fuse

Just got my truck back from the dealership for some service work. One of the items was the lumbar switch on the driver side, and another was the mirrors-both-not working any longer. Lumbar switch, or something, was replaced and now it works. Mirror motors both need to be replaced, but they did replace the switch. Bottom line is the motors are not available till Friday, and I need the truck Thursday to go hunting. I'll bring it back in Monday.

Picked it up this evening, and noticed the lights don't turn on when the door is open, the memory is lost on the seat position, and the lights on the seat warmer and the seat warmer itself don't work. Is this something as simple as a fuse? If so, any idea which one? I can't make out the abbreviations on the cover just inside the door, and it's getting a little on the cool side down here.

I say they may have removed a fuse my guess since all those seem to revolve around all around there. They may just have it unplugged till they can finish repairs. But the door light would be related to the switch on the dash around the interior light dimmer knob. But that is based on LTZ Dash.

The interior light was the switch. They must have hit it while they were working on it. Since I have always had it on, I forgot about it.

As for the memory and heated seat switch, he indicated it was all tied into a module that not only controls that, but also the mirrors, which are still messed up. The mirror switch was replaced, but fried out due to the motors not working properly. So, the module, mirror switch, and both mirror motors will be replaced Monday. I'll keep my fingers crossed.

They ended up replacing both motors, the switch, and some module, and all is well. Sure would have been an expensive job without the warranty.
