What is wrong with a 2002 Chevy Blazer that gives a little heat when the blower is on low but blows cold air when on high?
I own a 1999 Blazer with a 4.3L vortec engine. I had this problem and solved it by topping up the coolant level. I found if the coolant level got even a little bit low the heater would only blow out lukewarm or cold air. I know this sounds simple but it worked for me. DL Vancouver Island British Coulmbia
