Question about 2004 Chevrolet Blazer
The blower works and there is very little heat coming out (very little) in the summer when i put on the a/c ti will run hot
Sounds like you may be low on antifreeze. ck and top off as nec. then run vehicle again if was low. if engine is running at normal temp (around 195-200 degrees) and not fluctuating, then a possible restricted heater core is suspect. you can flush these cores out fairly easily at firewall under hood. (do this before replacing core, pressure washer works well). if engine temp is not normal(reads low) or fluctuates, replace thermostat.
