under the dash below the glove box
No. The ac and heater fan only has one resistor. The control switch is also failure prone on that vehicle.
bad blower resistor
Most likely a failed blower resistor.
this resistor is located next to the blower motor in the heater plenum. the coils sit in the air stream. remove the connector and the fasteners and pull the resistor block out.
By the clutch pedal two screws and a plug
If it works on some speeds and not others, the most likely problem is a defective Blower Motor Resistor Pack. It is located near the blower motor.
its to the right of the heater motor housing i believe the factory one is white in color
A blower resistor can be replaced, in your 2002 Oldsmobile, by removing the resistor wiring. Remove the retaining screws. Reverse the process to install the new resistor.
Bad resistor pack on blower motor? Bad switch?
The blower motor resistor is located right beside the blower motor which is on the right side of the instrument panel. You'll have to remove the lower insulator panel to see it. Remove the wiring connector and I believe there is 3 screws that hold the resistor in
To change the blower motor resistor in a 2002 Nissan Maxima, locate the blower motor resistor under the glove compartment on the passenger side of the vehicle. There is a clip that is depressed and then the resistor will slide out. Remove both ends of the resistor and then replace with the new resistor.
Generally the blower motor resistor is found close to the blower motor. It relies on the blower motor to keep it cool.
