Question about 2003 GMC Yukon
2003 gmc yukon with power seats and driver side heated seat will not stay on. Relay comes in then drops out immediately. Pulled seat cushion cover and element looks good, no burn marks. Disconncted wiring from both upper and lower elements and rung out with ohm meter and both appear ok. Tried to isolate driver seat and backrest elements seperately to determine if a short or ground was present on either element. Noticed that if either harnesses is not connect to plug-in, passenger side seat element will not work. Looked at wiring schematic for both driver and passenger seats to determine if there is a common that both seats share so that driver side must be connected for passenger side to work. This vehicle has a memory seat module which appears to control the logic control. Open for suggestions as to why driver seat will not stay on

I have had similar problem, after much power tracing and power bypass the problem was only solved when I cut out the under-seat connector and hard wired it....I suspect the design of the connector and the location is susceptible to corrosion from moisture
hope this helps

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.

See GM TSB 05-08-143-001, If you have Adjustable pedals, especially if they don't work with the memeory buttons, but function with thier own buttons. Its the Brake Pedal Position Sensor is shorted and mesing up the seat module which controls the heaters too. My 05 Suburban had the same issue
