I just bought a 2004 Chevrolet Tahoe with the 5.3L w/88K miles and the front seats are heated. If you only turn the passenger heated seat on everything is fine. But if you turn the driver heated seat on, it turns both the driver and the passenger off. No matter what, the driver side heated seat will not stay on. It lights up like it’s on and goes off immediately. After the driver side goes off, you can turn the passenger side on and it’s ok until you try turning on the driver side and the viscous cycle starts again. Any idea why the driver side won’t stay on and why it would turn the passenger side off? Any ideas appreciated.
