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. Can check by unplugging switch and see if heated seats work .

  • the heated seat control switch, located on the seat side trim panel.
  • temperature sensors located in the seat cushion heating elements.
  • heated seat relay.
Do both front seat heaters not work ? Do you know how to test electrical circuits with voltmeter ?

Gmc jimmy heated seat not working on one side only.

Hello-
If your fuses are good, perhaps your heated seat switch is faulty. You can test the switch for connectivity using a meter to see if power is going through the switch when in the ON position. If the meter shows no power while in the ON position, replace the switch. If power is reaching the seat, then likely the heating element itself within the seat is the culprit.

The drivers seat won't move and the heated seats won't work on both sides. Where is the fuse?

Check underneath the seat for an inline fuse. It is a glass type fuse in a fuse holder that you have to push and twist to get out.-----------------------------------------------------------------------------
