Heater problem
1999 Chevy Blazer 6 cyl Four Wheel Drive Automatic 100000 miles

The heat went out in my wife’s blazer I flushed the system, changed the thermostat, but still no heat what else can I check? Is there a heater control valve some where? If so where? Or is there a relay switch that could have wend out?

Might want to inspect the heeter hose and heater core could be clogged-up, heater control valve is normally attached to the hose-could be an air mix/blend door not opening due to an actuator being defective
