Could you please tell me why my blower motor is not working, I have change all of my vaccum lines. I was told that there is a relay by the water resevore that could be bad.

Is the fan working? Is the engine coolant full?

I WOULD CHECK THE PLUG TO THE BLOWER MOTOR TO SEE IF YOU HAVE VOLTAGE THERE FIRST, IF YOU DO THE BLOWER MOTOR IS BAD. IF NOT CHECKTHE RESISTOR THAT REGULATES THE SPEEDS TO THE FAN ITS IN THE ENGINE COMPARTMENT BUT YOU HAVE TO REMOVE THE WINDOW WASHER BOTTLE TO GAIN ACCESS, IF THATS GOOD CHECK THE SWITCH INSIDE. THIS HAPPENED TO ME AND IT WAS MY BLOWER MOTOR.

Hi
I am trying to determine if the fan is working or you lack heat. Let me know and I'll walk you throught the process of elimination.
