HEATER

2004 Chevrolet Blazer • 125,000 miles

Can not get air/heat to blow through floor vents. It defaults to defrost when floor is selected. All other vents working properly and air/heat is coming from other vents. My fear is the dash will have to be pulled for a repair.

Check for a vacuum leak first as it's operated by vacuum. It
s on the lh side top of hvac unit so you may be able to reach it. See pic.
