I have a 2000 suburban and was wondering if anyone else was experiencing the same issue I am having with my rear heat.
I cann't get the rear air to blow heat and was wondering if there is an electric coil somewhere that could be out.

My grandmother's 92 suburdan was doing the same thing about a year ago. The rear hoses had an air bubble in them that wasnt allowing watter to pass through them. After a flush and refill the system works great.
