Blower Motor Resistor / Control Module Replacement: labor quote guide
Typical labor time (approximate)
About 0.3 to 1.5 hours. Usually about 0.3 to 1.5 hours. Most resistors are behind the glovebox or under the dash.
Approximate only: a rough general range, not labor-guide data. Times vary widely by vehicle and condition. Check a labor guide for the exact vehicle. How we estimate
The quote buttons open the labor-quote calculator prefilled; "Start an estimate" adds a labor line to the estimate & invoice generator. Add your own rate, parts and tax.
What's involved
- Confirm which speeds fail and check power to the resistor
- Access and remove the resistor or module
- Inspect the connector for heat damage
- Install, test all speeds and check blower motor current draw
General outline only. Follow the service information for the specific vehicle.
What changes the time
- Burned connectors
- Electronic blower control modules
- Access behind the dash
- A blower motor drawing too much current
Related parts & common add-ons
- Connector pigtail
- Blower motor if current draw is high
- Cabin air filter
- HVAC control head check

FAQ
Why do resistors fail again?
A blower motor drawing too much current can burn out resistors repeatedly. Check the motor.
Only high speed works?
That's a classic resistor failure, because high speed often bypasses the resistor.
Connector melted?
Replace the connector pigtail along with the resistor.
