I have an '01 chevy blazer with about 108,000mi. The only time I can get any heat from it when the heat setting is maxed out, when you turn it to say 74 it only blows cool air. Also the blower when turned off will bolw air thru the dash vents when ever you you go into passing gear or step on the gas pedal for extra boost as in going up hills. I have changed the thermostat and added coolant but still have the same symptoms. I have been wondering if the electronic control in the dash is bad. I appreciate any adive.
have the same problem?
