2000 Astro only has high speed on heat fan

Postby Vaughn [OP] » November 15th 2017, 5:34am

My Astro fan motor just quit working on anything but high. Is it usually in the motor or is it the switch in the dash.
I am going to have access to switch when I put in a new radio, I could easily put in a new switch while I have access.
Don't want to wait till the motor totally quits. It's getting cold here in Pa

Either the blower motor resistor or the main vacuum line.

Usually the resistor/controller at the blower motor.

Vacuum line is when it jumps to or stays on defrost.

Trolls take away from productive work, best to ignore them & go about your business.

Yep. Blower motor resistor is my bet. Very common. When they go out the resistor fails and you only have on and off nothing in between.
