I have a 2000 tahoe that has a rear heater problem Both control for the rear heater won't work. It won't go from hot to cold or the fan blows the same speed no matter where you have both of the controls. The only thing that I can do is pull the fuse to shut it off completely. Could the relays for the rear be bad?
