Strange problem here. Usually, when you push the seat heat button it cycles through Hi Lo Off with each push of the button.
All of a sudden, pushing the button just cycles Lo Off Lo Off, never Hi. There no 'dead' position, ie Hi, but no light.
Passenger seat's still working fine.
Only thing that's changed is I replaced the driver side rear view mirror with a heated, but not auto dimming, one. I really can't see how the auto dim side mirror function would be tied in.
Anyone else ever seen this on a GM ?
