Buying a Used Heater Blower Motor from a Junkyard

Why Consider a Used Heater Blower Motor from a Junkyard?

When your vehicle’s heating system fails, purchasing a used heater blower motor from a junkyard can be an excellent cost-effective solution. With new OEM blower motors costing over $200, junkyard alternatives typically cost around $70 or less, offering substantial savings without sacrificing quality.

Many auto enthusiasts have discovered that junkyard blower motors from low-mileage vehicles often outperform new aftermarket replacements. This is particularly true when it comes to noise levels and overall durability, making salvage yards an increasingly popular option for HVAC repairs.

Understanding Blower Motor Problems and Symptoms

Before heading to the junkyard, it’s crucial to properly diagnose your vehicle’s heating system. Understanding common blower motor failures will help you make an informed purchase decision and avoid unnecessary replacements.

Common Blower Motor Symptoms

• Weak or no airflow from vents
• Unusual noises like whirring, rattling, or screeching
• Fan only works at certain speeds
• Intermittent operation or complete failure
• Burning smell from the HVAC system

It’s important to note that many blower motor issues actually stem from the blower resistor rather than the motor itself. The resistor controls fan speed by regulating voltage, and when it fails, you might experience limited fan speeds or fans that only work on the highest setting.

Problem	Likely Cause	Solution
No airflow at all	Blown fuse or bad motor	Check fuses first, then motor
Only works on high speed	Failed blower resistor	Replace resistor, not motor
Loud noises	Worn motor bearings	Replace blower motor
Intermittent operation	Loose connections	Check wiring and connectors

How to Test a Used Blower Motor Before Purchase

Testing a used blower motor before purchase is essential to ensure you’re getting a functional unit. Many reputable salvage yards and used parts suppliers now test and inspect their HVAC components, but it’s still wise to verify functionality yourself when possible.

Bench Testing Method

The most effective way to test a used blower motor is through bench testing:

• Connect the motor directly to a 12V power source (car battery or jump starter)
• Ensure the fan has adequate clearance to spin freely
• Listen for unusual noises like squeaking or grinding
• Verify smooth operation at different speeds if possible
• Check for proper amperage draw using a multimeter

Multimeter Testing

For more thorough testing, use a multimeter to check electrical continuity:

• Set multimeter to “resistance” or “ohms” setting
• Disconnect motor’s lead wires
• Touch probes to motor terminals
• Normal reading: 1-20 ohms
• Infinite resistance = open circuit (defective)
• Zero resistance = short circuit (also defective)

“I bought a junkyard blower motor pulled from a Frontier with 3K miles for $70, installed it, and it runs quietly—better than several new aftermarket fans I tried that whined or squeaked.”
