hey guys, i need your opinion. Here is the problem : I have no heat in my car. At first i thought it was the thermostat so i change it and still nothing. Then i move to the blower but it work perfectly. Then i found out that when i turn the knob to defrost the windshield and put it on 1,2,3, or 4 ( fan power) it wouldn't activate the blower but the fan in the engine !!! Also when i press on the a/c button it will also activate the fan in the engine!!!
So what should i do and check, I'm out of my knowledge area
