Detailed Description
This Dorman HVAC blower motor resistor kit is made for vehicles that have lost one or more blower speeds due to heat damage, corrosion, or connector wear at the resistor circuit. Part number 973-527 is a practical OE-style replacement for rear, center, and N/A-position HVAC applications across select Ford, Lincoln, and Mercury models. It cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Compatible With 1995-2001 Ford Explorer, rear; 1997-2001 Mercury Mountaineer, rear; 1997-2002 Ford Expedition, console blower; 1998-2002 Lincoln Navigator, center; 2001-2005 Ford Explorer Sport Trac, rear; 2003 Ford Explorer Sport, rear; and 2002-2003 Lincoln Blackwood, N/A. Use Dorman 973-527 when the original resistor or connector shows signs of overheating, melting, or corrosion.
Common Repair Symptoms
- Blower motor works only on certain speed settings
- No airflow from the HVAC blower on lower speeds
- Burned, melted, or corroded resistor connector
- Intermittent cabin fan operation
- HVAC fan speed control failure after heat-related connector damage
Installation Notes and Tips
Inspect the blower motor connector, resistor cavity, and surrounding wiring before installation. Replace any heat-damaged terminals or wiring sections so the new resistor and harness can make a secure electrical connection. Confirm the vehicle position and connector style against the listed fitment before installation.
Quality Assurance
Dorman supplies replacement electrical components for repair-focused applications, and this kit is built to address common resistor and connector failures found in select Ford, Lincoln, and Mercury HVAC systems. Part number 973-527 is intended to restore blower speed control after the original resistor circuit has been damaged.
