After 115K the blower motor resistor pack went out causing the motor to only work on high and off. changed part and a week later it went out again. So, O.K. I got a bad part. Returned to Ford and got another one, Same thing in about a week. Is there something causing this or do I just have another bad one? Thanks, Matt.
I would check to see how much current the motor is drawing.... Also verify that the resistors in the pack are, in fact, open i.e. bad. If they still have resistance, then you need to check the switch and/or wiring
Hmmmm. Not sure I can help. Testing the current draw of the motor is very easy with the right equipment, but you would know that if you had an ammeter/ VOM.... Do you know anyone with some electrical experience?
i also hav a Astro van was doing same thing. but the motor was just alittle heavy. So i changed both. But I changed the resistor twice. And the third time, ended up the plug got lose.
But if blower is less then 50 buck try it.
I had already changed the resistor pack and it burnt out again. I pulled the motor off and compared it to a new one and it was harder to turn. Never did test draw on old motor.
