Tell me where I find the resister
Expert:  john replied 8 years ago.
resistor is mounted to the inboard side of the heater-A/C housing in the engine compartment. It can be accessed for service from the engine compartment.

The optional rear heater-A/C unit has a blower motor resistor mounted to the inside of the unit lower housing in the passenger compartment.

The front blower motor resistor is located in the engine compartment on the inboard side of the heater-A/C housing. The rear blower motor resistor is located in lower housing of the rear heater-A/C unit in the passenger compartment.
