my 97 F-350, has decided to not blow heat or a/c??
I checked the fuse and its good, But i have no speeds for the fan?
WIll the blower motor just die??I thought it would go out a slow death?
Anything else i can check or just chck for voltage out at the fan?
Check the voltage at the fan. If you have it, then you can be pretty sure it is the motor. If not, maybe you have a bad switch or some kind of open circuit between the switch and the motor.
