Key Features
- Includes a blower motor resistor and wiring harness pigtail for a direct repair approach
- Uses blade-style terminals with a female connector and male terminal interface
- 7.3-inch wiring harness length for connector replacement work
- 4-wire harness configuration with 2 connectors
- Designed for 1997-2001 Cadillac Catera, automatic air conditioning controls
- Dorman part number 973-123 for easy identification and ordering
Detailed Description
This HVAC blower motor resistor kit addresses common electrical failures at the blower resistor connection point. On the Cadillac Catera, heat and corrosion can damage the original resistor and connector, leading to inconsistent fan speeds or loss of blower operation. Dorman 973-123 provides a replacement resistor and harness pigtail to restore the circuit connection and blower speed function.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It is a practical repair solution for 1997-2001 Cadillac Catera HVAC blower motor resistor replacement needs, especially when the original connector shows signs of overheating or corrosion.
What It Helps Fix
- Blower motor only working on certain fan speeds
- No cabin airflow from the HVAC blower motor
- Intermittent blower operation caused by a failing resistor circuit
- Heat-damaged or corroded resistor connector terminals
- Electrical resistance issues at the HVAC blower control circuit
Installation Notes and Tips
Verify vehicle year, make, model, and automatic air conditioning control configuration before installation. Inspect the blower resistor connector and surrounding wiring for heat damage before splicing in the supplied harness pigtail. Use proper butt-connector splicing practices and confirm secure terminal engagement after installation. This part is listed for 1997, 1998, 1999, 2000, and 2001 Cadillac Catera applications.
Quality Assurance
Dorman supplies replacement electrical and HVAC service parts engineered to address worn or damaged original components. Part number 973-123 is cataloged as an HVAC blower motor resistor kit for the specified Cadillac Catera fitment.
