I have checked fuses for the rear airconditioner blower that will not come on. My front air is fine, but rear air blower will not come on. All fuses seem to be ok. I have not checked the selector switch. Can you help. 1989 gmc suburban. Thanks for your help.

Test the auxiliary control switch and rear blower motor resistor.
