Dorman 973-403 blower motor resistor kit for the 1995-2005 Chevrolet Blazer and other vehicles replaces an overheated or corroded original equipment resistor. As a Dorman HVAC blower motor resistor kit, it directly replaces the original equipment on select vehicle years, makes and models.
- Complete kit: one resistor and one harness pigtail, which is essential for most repairs
- Made to perform like original equipment, to help restore full HVAC operation
- Backed by a team of engineers and quality specialists in the USA
A blower that runs on only some speeds, or not at all, can mean the resistor has overheated or corroded. Before you replace it, rule out a blown fuse, a worn blower motor and a damaged connector, since each can also stop airflow. The 1995-2005 Chevrolet Blazer takes one.
The kit also fits the 1994-2004 Chevrolet S10 and the 1994-2004 GMC Sonoma, plus other vehicles. If your vehicle isn't one of these, look it up in the "Vehicles it fits" section.

Frequently Asked Questions
Does the Dorman 973-403 fit a 1994-2004 GMC Sonoma?
Yes, Dorman 973-403 fits the 1994-2004 GMC Sonoma, the 1995-2005 Chevrolet Blazer and the 1994-2004 Chevrolet S10. For other vehicles, look yours up in the "Vehicles it fits" section.
What is in the Dorman blower motor resistor kit?
Dorman 973-403 comes with one blower motor resistor, one pigtail connector and four butt connectors. A gasket or seal and mounting hardware are not included.
What terminals does the Dorman blower motor resistor have?
This kit has four male blade terminals, a female connector and a 6-inch harness. It also has four wires and three mounting holes.
Could a failing resistor be why my blower works on only some speeds?
Yes, it can. The resistor sets the blower's fan speeds, so an overheated or corroded one can leave the fan on only a few speeds or dead, and this kit replaces that resistor.
Does Dorman 973-403 interchange with RU344 or 15094285?
Yes, Dorman 973-403 is listed as a replacement for RU344 and 15094285. The same list also includes 3A1034, RU1027, 20267, 15652873, RU344T and DR773.
