Question about 2003 Chevrolet Silverado 2500HD
My 2003 suburban has heated seats, when I turn the heated seat on the drivers side on, it comes on, then I hear a click from under the seat, and it goes off. It will only stay on maybe 1 second, the passenger side works fine until you turn driver side heated seat on, then they both go off. Any advice or help would be greatly appreciated. Thank you Same thing, passenger side works fine until I turn on the driver side. I believe the click is from under the dash. This looks to be a common problem with GM.
Identical thing here with my '03 Surburban LT.

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
