IT SEEMS MY A/C NEEDED THE RESISTOR REPLACED. MY AIR/ FAN WOULD STOP WORKING WHEN I WAS DRIVING. IT ALSO SEEMED THAT WHEN I USED MY FAN, A/C, HEATER, THEN THE NEXT DAY THE BATERY WAS NOT CHARGED. I HAVE HAD THE BATERY/ALTERNATOR CHECKED, IT 'S OK. THE BATERY IS ONLY 6 MONTHS OLD. THE MECHANIC JUST PUT IN A NEW RESISTOR, BUT IT WAS NOT EXACTLY LIKE THE ONE HE TOOK OUT SO HE HAD TO DO ? SOMETHING W/ THE WIRES. NOW, IT WON'T BLOW ON HIGH. I AM GETTING THE RUNAROUND FROM HIM. ANY HELP? (NOW HE SAYS IT MAY BE THE FAN MOTOR, MAYBE.

The fan blower motor resistor is a common failure, you need the exact same on for the fan speeds to work properly, easy to test, and replace. The part is less than $75 from the dealer. The blower motor is also easy to test or replace. Its held into the heater housing under the dash on the passenger side with three screws. With the wires to the motor disconnected supplying power and ground to the motor would verify if the motor is OK. I have see rodents build a nest in the fan motor but you would see this on removing the fan motor. This isn't a complex repair, tests are also pretty simple, don't pay for a part that doesn't work or fit.
