Replace an overheated or corroded blower resistor with the Dorman blower motor resistor and harness kit, part number 973-406, a direct replacement for the front blower motor resistor on the 1996-2005 Chevrolet Astro and 1996-2005 GMC Safari. The resistor controls the current sent to the blower motor to provide the lower fan speed settings. See the Buyer's Guide tab for engine details.

Dorman supplies a new resistor together with a harness pigtail. You replace the original resistor and its connector at the same time.

  • Direct replacement: Designed to directly replace the original equipment resistor and harness on the listed applications.
  • Resistor plus pigtail: Each kit includes a resistor and a harness pigtail. Dorman notes the pigtail is essential for most repairs.
  • OE-like performance: Made to perform like original equipment. If a failed resistor is causing your HVAC problem, it is intended to bring full blower operation back.
  • Engineering support: Backed by Dorman's team of engineers and quality specialists in the USA.

Signs this part may need replacing include a blower that runs only on its highest setting, fan speeds that don't work, or a burnt or corroded resistor connector. A faulty blower motor or switch can cause similar symptoms, so diagnose the cause before replacing parts.
