Having problems with your 2003 GMC Yukon Denali ?
My 2005 Yukon XL is not blowing heat out of the Rear. Front works fine, and rear blower works fine. I check all related rear fuses and they are fine...what next?
Check and make sure the duct work going to the rear vents are attached and in good condition
