Driver side door has no power and heater/defrost working but no heat
My 2007 Yukon XL shows as “driver side door open” on dash. No power going to the driver side door (has been intermittent) but now longer works at all. There is no power to move the mirrors, heat seat, lock doors/open windows. In addition, my fan blower works on heater and defrost, however, on driver side the air is only blowing cold, no heat. It is heating on passenger side both in defroster and cabin fans. Both went out at same time, during the last couple days here in the Midwest and today we are getting an ice storm. Any help appreciated!
