Dorman 973-523 HVAC Blower Motor Resistor Kit

This Dorman HVAC blower motor resistor kit restores blower speed control on select Chrysler PT Cruiser models. It includes the resistor and a replacement harness pigtail for vehicles with an overheated or corroded original connector.

  • Direct replacement HVAC blower motor resistor kit for select Chrysler PT Cruiser applications
  • Includes a 4-terminal resistor with blade terminals and a female connector
  • Harness pigtail measures 6 inches and uses 4 wires
  • Built for vehicles where the original resistor connector has heat damage or corrosion
  • Part number 973-523 for service and catalog lookup

Fitment and Application

Compatible with 2001-2010 Chrysler PT Cruiser HVAC blower motor resistor service. Fits 2001-2010 Chrysler PT Cruiser, N/A.

This part cross-references Monroe Shocks & Struts (e.g., RU478, RU1171) for the same application.

Detailed Product Information

Dorman 973-523 is an HVAC blower motor resistor kit that combines the resistor and harness pigtail needed to address common electrical failures at the blower motor circuit. The 4-terminal, male-blade resistor connects through a female harness interface, while the included wire harness helps replace damaged OE wiring at the connector. For Chrysler PT Cruiser blower speed repair, this kit supports a cleaner electrical connection where the original resistor or plug has overheated, loosened, or corroded. Use part number 973-523 when searching for a replacement blower motor resistor kit for 2001-2010 Chrysler PT Cruiser models.

Common Problems This Part Can Address

  • Blower motor works on only one speed or loses multiple fan speeds
  • Intermittent HVAC fan operation caused by a failing resistor circuit
  • Heat-damaged or melted resistor connector at the harness plug
  • Corrosion at the original electrical connection
  • Loss of cabin airflow control from a worn blower resistor assembly

Installation Notes and Tips

Inspect the blower motor connector, resistor cavity, and surrounding wiring before installation. If the original plug shows heat damage, replace the affected connector section rather than reusing compromised terminals. Verify terminal orientation and secure the harness routing away from heat sources and moving HVAC components. Confirm the vehicle application before ordering, especially on 2001-2010 Chrysler PT Cruiser blower motor resistor repairs.

Quality Assurance

Dorman supplies service replacement electrical components for vehicle repair applications. This kit is built as an OE-style replacement for the original blower motor resistor and connector assembly on listed Chrysler PT Cruiser models.
