No heater on rear system on 2003 escalade
having problems with my 2003 escalade. need help. the front ac system workds great, i have a/c and heater. but on the rear system, i can turn the control from cold to hot and all i get is cold air, the other controls vents from head to feet and works perfect. i replaced the actuator and same problem, but we can take off the actuator and switch it to give out hot air, any suggestions out there. thank you
