The passenger heated seat works? All the functions are controlled by the memory seat module, heated seat functions are through bussed messages to the climate controlled seat module. Since you have memory seat/steering column issues, I would suspect your source of problems to be from the memory seat module. Aside from checking powers and grounds to the seat module, I would first do a master reset on all systems. Disconnect both battery cables, and touch them together firmly for a minute or so. See if all your problems are resolved. You only have two elements per seat, and the heated seat switch is part of the climate control panel. To replace the switch/panel would be an expensive shotgun. It sounds like you have a logic lock condition, and performing the above reset procedure will correct the condition if that is the case.

Did this work? Both of my seat warmers are out and when I moved the passenger seat forward for easy access to the rear seat fuse blocks, the seat has frozen in the full forward position.

Hey JUDYFAYE,

Before you go to the shop I think I found the problem. There is a ignition 1 relay that control both systems, and two fuses here is there location and a couple of guide to help you get the problem fixed.
