Driver Heater and Passenger AC blowing at the same time

Asked by 2004ChevyAvOwner May 20, 2018 at 10:19 PM about the 2004 Chevrolet Avalanche 1500 4WD

Question type: Maintenance & Repair

I had the blower replaced in my HVAC system and after I got the truck back, the driver side heater blows while the passenger side AC is running.  Doesn't matter if I have AC, heat or Auto selected, it stays this way.  The engine light is on all the time.  Checking to see if there is anything I can do to troubleshoot this problem.  Any suggestions?
