When I shut the car off the AC Blower kepts runnig. My mechanic said
that Blower Motor Resistor is faulty, so I bought it and now...he has
no clue where that thing is located in the car. Any idea?
Thanks

 

I dont know for sure but usually the resistor block is located near the blower motor. I would remove the glove box to gain acess to the blower motor. If its not located at the motor, follow the wires from the motor untill you located the ressistor block.
