Product Details

The Four Seasons Resistor Block line is built for HVAC blower motor circuit control in vehicles that use a resistor-based fan speed system. This resistor block regulates blower motor operation at the specified speed setting and is a practical replacement when the cabin fan no longer responds correctly at one or more speeds. Part number 20128 is engineered for the listed Nissan fitments and is a straightforward OE-style service part for HVAC repair.

This part cross-references TYC 20291 and UAC SW8395C for the same application.

Vehicle Fitment

  • Fits 1995-2006 Nissan Sentra, N/A
  • Fits 1998-2004 Nissan Frontier, N/A
  • Fits 2000-2004 Nissan Xterra, N/A
  • Fits 1995-1998 Nissan 200SX, N/A

Common Problems This Part Can Address

  • Blower fan works on only one speed
  • Cabin fan speed #3 does not operate correctly
  • Intermittent HVAC blower motor speed control
  • Loss of proper resistor-based fan output
  • Need for a replacement HVAC blower motor resistor on Nissan Sentra, Frontier, Xterra, or 200SX

Installation Notes

Verify connector style, terminal count, and vehicle application before installation. This resistor block uses a female rectangular connector with 4 spade terminals, so the mating harness should match the original configuration. Confirm the HVAC system is set up for a fixed speed #3 resistor before replacing the part.
