The resistor is mounted to the heater case on the passenger side of the vehicle. There is a hush panel that you will have to remove first. The resistor is mounted with three very small hex headed screws. My advise is to remove the one closest to you when you are under the dash, and only loosen the other two which are very hard to get at. Sometimes, you can't get to them at all, so you will need to bend the resistor down and pull towards you while rocking the resistor. It should pop out with some effort. While the resistor is out, loosen the two hard to reach screws just enough to make it easy to reinstall the new resistor, then install the resistor and the third screw. You shouldn't have to tighten the other two screws. Connect all related wiring that goes to the resistor and the blower motor. There is one other thing to worry about on these cars. There is a water deflector under the wiper cowl panel outside the car that can sometimes fall off. When this deflector/ weatherstrip falls off, it will allow water to hit the blower resistor and will cause it to fail prematurely. Make sure this is installed correctly to avoid a repeat failure.
