Four Seasons HVAC Blower Motor Resistor P/N:20903
Get your fan speeds working across the dash again with the Four Seasons switch — the HVAC Blower Motor Resistor, MPN 20076. This FRONT-mounted resistor sets the current path to the blower motor, dividing it into the stepped fan speeds you select at the control panel; when a resistor circuit fails, the blower often runs only on high or drops certain speeds. It's a direct-fit replacement for many 1990-1995 GM trucks and SUVs, including the 1993-1994 Chevrolet Blazer, Chevrolet C1500 and K1500, GMC C1500 (1990 and 1993-1995), GMC Yukon, and the C/K 2500 and 3500 Suburban variants. See the Buyer's Guide tab for the full list of applications and engine details.
If a failed resistor is the cause of your missing or stuck blower speeds, this unit replaces it. Confirm your vehicle in the fitment list before ordering.

This part cross-references / interchanges with the following part numbers:
What does this blower motor resistor do?
It adds resistance to the blower motor circuit to create the stepped fan speeds you choose at the HVAC control panel, regulating current to the blower motor.
Is this a Four Seasons switch that fits my truck?
It's Four Seasons MPN 20076 and fits many 1990-1995 GM trucks and SUVs. Check the fitment list and Buyer's Guide tab to confirm your exact vehicle and year.
Why does my blower only run on high speed?
A failed resistor circuit commonly leaves the blower working only on high or missing certain speeds. If the resistor is the cause, this part replaces it; diagnose the circuit first.
Where is this resistor located?
This is a FRONT-position HVAC blower motor resistor. It plugs into the blower circuit via OE style connectors on the listed applications.
Which interchange numbers does this replace?
It cross-references 19336636, 11120076, 973037, 901214, 15991075, 1712699, A07863, MT18016, SW11295, SW11295C, and DR790.
