Seat heaters won't stay on

[Noto81]

Long story short the front seat heaters in my 03 Yukon SLT won't stay on. They stay on for a minute or so, not long enough to heat the seats anyways, and shut off. It started randomly a week or so ago and its in both driver and passenger seats and doesn't matter if its the seat/back heater or just the back heat. Any ideas?

Heating elements might be going bad, just a guess though.

mine does the same thing except that my passenger stays on without problem until i hit my drivers side button then pass will shut off. and drivers side just shuts off after about 20 sec

yes elements worn, Way too much resistance somewhere. It shuts down so you dont get burned or the circuit fries

i that is the case why would it shut down the pass side which works fine till i turn on the driver's side? pass side stays on for as long as i want.

Maybe they run on the same circuit.

Both seats run off the same module and when one has a problem it turns everything off. If you can run one side without trouble, that side is fine. Whichever side shuts off will need heater elements. They are replaceable separate from the seat cover or cushion. Many dealers will keep them in stock.
