The new blower motor resistor part matched the one I took off - they both looked like the one pictured here: 4. The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. 4Seasons/Everco (1) Dorman (1) Duralast (1) Santech (1) This is a test. If not OK, replace the faulty blower motor resistor block. I'd hate to replace the blower motor only to find out it's the switch or something else. I have no blower motor at all when all wires are connected. Reconnect the negative cable to the battery. This will supply control voltage to the resistor, which in turn will run the blower. I used 3 x 20cm lengths of heavy gage wire from a spare loom I had available, 6mm dual wall heat shrink ($5.00) and a packet of 2.5mm female spade connectors ($2.35). How to Troubleshoot a Blower Motor Resistor. If you’ve replaced a blower motor resistor and that replacement has failed, it’s time to conduct an amperage test on the blower motor.
