Question about 2003 Cadillac Escalade Esv
Read climate control works the fans and vents fine but i am getting no hot air. Front heat works great. Is there some valve solenoid or damper control that diverts heat to the rear? Could it be defective? Can I replace it myself?
There are two separate actuators for the rear system. one controls temperature and the other controls vents from head to feet. mine problem was the later. that acutuator for esv 2003 is 89018365. it is located just below third seat cup holder passenger side and can be replaced simply by removing cup holder. triangular shaped part with wire harness.
