Seat Heaters in 2004 Yukon turn off after a few minutes

The seat heater in the drivers seat has started to turn off after only being on for a few minutes. I was messing with it this morning and it started to turn off as soon as I would press the button....after I turned the car off and back on it stayed on longer but still went off on its own....any ideas??

My power seat stopped working in my 2003 Yukon XL. The heated seats stopped working as well.

Try this remove the ckt breaker for the power seats the ckt breaker is located in the fuse box inside down by the drivers left foot. leave breaker out for about 10 seconds then reinstall it and see if the seat starts moving. If it does there is a reprogram for this and needs to be done by a dealer or someone who has access to be able to reprogram your vech.
several things could cause your heated seats to not work. If the seat and heated seat seat stopped at the same time could be the reprogram could fix it. If the heated seat quit working at a differant time it could be the seat heater element. get a schematic of the heated seat and ohm the wires for the element. If either element tests open then the element will need to be replaced. You might as well replace both of them at the same time since the seat covers have to come off to replace the seat heaters.(back and bottom ) If one element is bad then both heaters quit working.

Our Driver Seat Heaters and passenger seat will turn on for 2 sec

When this was happening on my Envoy it ended up being the seat heaters control module that was going out. About $600 a seat on mine. Just wish my repair center found that out before they replaced the seat heaters twice.

The seat heaters are designed to heat up and once they hit a preset temp, they turn off. That said, if your won't stay on for even two minutes then you will have to replace the seat heater relay. The part is available at GMC dealerships and some auto parts stores.

Heated seats won't stay on in 2004 GMC Yukon Denali

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
