What causes a blower motor resistor to melt?
What causes a blower motor resistor to melt?
Arching is what’s melting the connector. when you put the connectors together it may be a good idea to take a scratch awl or pick and squeeze the spade connectors in the plug tighter. You must log in or register to reply here.
When did the blower motor on my Blazer stop working?
2005 T’Blazer, 6 cylinder, manual A/C controls. Maybe 6 months ago, blower fan speed 5 stopped working, followed by the rest shortly after. Following the great advice on this forum, I checked the blower motor resistor and plug, and replaced as advised.
Can a blower motor go out and smoke a resistor?
A blower motor that is going out can smoke a resistor. I lost #5 (no melting, relay in resistor crapped out) and after replacing the resistor the motor clamped at 23A and some change. I replaced the motor just to be on the safe side and it was right around 22A.
Can you check the draw of a blower motor?
You can check the current draw of the blower motor with a 12V battery/power supply and a DMM to be sure. given all the good responses I’ve gotten here, is to buy the connector plug that the Captain linked to, a new Delco resistor, and install them. The blower motor seems fine, it sounds and runs as it always has.
Is the blower resistor on my GMC Sierra on fire?
This was preformed on a 2004 GMC Sierra with a blower resistor that had been on fire and melted the wiring. Loading…

Where is Dorman HVAC blower motor resistor kit made?
This HVAC blower motor resistor kit includes a resistor and harness pigtail to replace an overheated or corroded original equipment resistor on certain vehicles. Dorman is a leading auto parts manufacturer founded in the United States and headquartered in Colmar, Pennsylvania. Our story began with the first mass market automobile.

What was the wire that melted on my blower?
One of the center wires is burned and melted about 1/4 inch outsode the plug. By wiggling that wore I can get speeds one through four to work again, but the wore and plug get really hot. I bought the connector and resistor at Auto Zone last time, the one that’s in there now.
Why does my Dakota blower resistor keep going bad?
When your Dakota or Durango left the factory, it had a Mopar motor and voltage resister that were compatible with each other. After 10-15 years the motor wears out , begins to draws more amps burns up the resister. Most people replace the wiring harness and the resister with. cheap replacement from Autozone / Advanced etc.

How to test a blower motor resistor in the garage?
Look for obvious signs of corrosion and burns from overheating. If you want to do a quick test of the blower resistor, you can check the resistance of each of the resistors with a multimeter as follows: set the tool to read ohms (a measurement of resistance) and connect one of its probes to the common output terminal of the resistor.
