REAR HEAT AND AIR

2004 Cadillac Escalade Esv • V8 AWD Automatic • 108,000 miles

My rear heat does not work although the fan controls are working and blowing air. The front system is working fine.

You'll have to take this in to getlooked at there is an actuator for the rear hvac unit. Either the control unit in the rear isn't sending a signal to the actuator or the actuator is getting the power and not operating. I can send the wiring diagram if you really want to check this yourself.
