Why do you need a blower motor connector?
The blower motor connector links the blower motor to the blower motor resistor. The blower motor is part of your vehicle’s air conditioning and heating system that pushes air through your vehicle’s vents. Without it, there would be no circulation of air. The blower motor resistor allows you to change the speed of the fan and the flow of air.

How does the resistor on a blower motor work?
The blower motor resistor allows you to change the speed of the fan and the flow of air. The blower motor connector joins the two and sends a signal from the blower motor resistor to control the speed of the blower motor.

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.
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.
Where can I get a new blower motor resistor connector?
Fortunately, swapping out the blower motor resistor connector is a straightforward job you can handle yourself with replacement parts from BWD or Dorman . No Interest if paid in full in 6 months on purchases of $99+ Check out with PayPal Credit Subject to credit approval.
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.
How is the speed of the blower motor controlled?
The electronic module that controls the speed of the blower motor is called a blower motor control module. In some cars, the blower motor has only 4 or 5 fixed speeds. In this case, the speed of the blower motor is controlled by a blower motor resistor.
What should I do if my ECM blower motor does not run?
If the motor runs the problem is in the low voltage thermostat wire. If the motor does not run, remove the 16 pin plug from the IFC board. Locate pins 12 and 15. Connect 24 volts from R to pin 12 and pin 15. Connect pins 1 and 3 to the common side of the 24 volt transformer (fig. 4). The motor should run. ECM Blower Motor Quick Test
