1986 F-150 Heater Fan Blower
Hello Everyone,
I have a 1986 F-150 with 41k miles that my grandfather bought new and handed down to me. I just noticed that when I turn on the heater the blower motor to the lowest setting barely blows any air, then when I turn it to the 2nd position it doesn't change, then when I turn it to high it blows hard. Would this be a problem with the blower fan motor or would it be in the switch? Its starting to get cold here and I want to fix this as soon as possible.
Thanks
Alan

Its probably your resistor thats not changing your speed. Its under the hood, passenger side firewall. This is it for a non ac unit. Also you should remove the slide vents in your kick panels and use a shop vac to vac out all the junk.
