My 2006 gmc yukon xl drivers seat will not move
Under the drivers seat at the rear is a black plastic cover. Remove the cover , it is over the main harness to the seat. Unplug the seat harness and inspect the connection. I see alot of these get knocked loose or get corroded. Good Luck.

Seat heater comes on by itself in 2004 yukon denali
Heated Seat Components
The heated seat system consists of the following components:
• Driver and passenger heated seat switches
• Driver and passenger seat back heater elements
• Driver and passenger seat cushion heater elements
• Driver and passenger seat back temperature sensors
• Driver seat module
• Driver door module
• Passenger door module
When there are modules involved in the operation of any componet that's acting up , the module's electronic's could be the culprit ! But without testing who's to say what the problem could be !
I would have it check for DTC'S
DTC B2425 or B2430
The driver and passenger seat heaters are controlled by the driver seat module. Power is supplied to the driver seat cushion and back heater elements through individual voltage supply circuits. Power is supplied to the passenger seat cushion and back heater elements through a common voltage supply circuit. All of the driver and passenger seat heater elements are grounded by the driver seat module through individual low side drive control circuits. The heater element control circuits are pulse width modulated to ground by the driver seat module in order to control the seat temperatures by regulating the current flow through the heater elements.
DTC B2435 or B2440
The driver seat module relies on inputs from thermistors installed in the driver and passenger seat backs to control heated seat temperatures. The thermistors are 2-wire sensors supplied with a 5-volt referenced signal circuit and low reference circuit from the driver seat module. Resistance through the thermistors varies with temperature causing the heated seat sensor signal circuit voltage levels to decrease as the seat back temperatures rise.
Install a scan tool.
Start the engine.
Turn the heated seat ON.
With a scan tool, observe the Heated Seat Sensor parameter in the data list for the driver seat module.
Does the scan tool indicate that the heated seat sensor parameter is within the specified range?
0.078-4.94 V
