Seat heater

[[__--MUD--__]]

Just yank that above plug under the seat. The door module is what powers it.

There is a tsb on the heating elements not working all the time when turned on, but I see nothing about them being on by themselfs.

There is updated firmware for the door control module for 2003-2005 that corrects the issue in that tsb. Might try getting a dealership to reprogram that module. All the diagnostics requires a tech2.
