ok, I have a 2000 vw passat. The blower wouldn't work till is at full. Also if the ac is on, as soon as the blower start working the ac goes off. any ideas?

replace your resistor box.

thank you, where is the box resistor located?

it should be right beside the blower , you will see a block of wires plugged in think there is four wires, one of the wires will be going too the blower.

thank you for your help. it was the blower motor resistor.:biggrin:
