Just a quick question... I have an '01 Suburban that the rear A/C is completely inop... It will not work using the front or rear controls in any cofiguration (heat, cool, auto, manual)... I have checked all the fuses and relays that I believe are related to the system and all are good... Thought maybe I was missing something... Any ideas would be greatly appreciatted...

 

Thanks,

David

Could be RR HVAC fuse, Blower motor, Blower motor control processor, Aux control, etc. Could be lots of things. Need some diagnostic information.
