I have a 1998 chevy blazer 2wd 4.3 engine. Have no heat. We have changed the heater core, thermostat, blend door actuator and still no luck. Both heater core hoses are hot. Can feel the heat inside when glove box is out but not coming thru any vents as hot air. The air is luke warm. Please help. Brooke

Your gonna have to remove actuator and manually move door to see it that helps.

Did you get right actuator? There are 2, 1 manual and 1 auto climate controls.

I am unsure which one it is. Not sure on how to manually move the door. Where exactly is the door at?
