What is a wax motor?
Answer Hello Myself. The motor on the right side of the part picture. It is a black square box with blue writing.
Is it possible to test the wax motor?
Answer Hello Karl. Yes, you can test the resistance on a wax motor, or you can test for power coming to the wax motor. If there is power there and the vent 8545533 does not work properly, replace the vent assembly. Hope this helps.
