Heater blower resistor is what controls the low medium high speeds...
Your truck has both. the resistor is between the switch & blower.thje resistor controls the blower speed
Resistor is located behind the blower motor assembly.
Blower fan resistor controls electric current to the fan motor to maintain different speeds.
The blower is controlled by the blower switch, blower resistor, and relevant power relay.
Common causes, blower motor resistor, blower motor, wiring or controls
the blower resistor controls the fan speeds
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.
The blower resistor controls the speeds of the blower motor Hi-resistance lower motor speed Lo-resistance higher motor speed
Check for a bad blower resistor at blower motor
its behind the blower motor under the passenger side of dash
