Heater help!
Ok i am a welder and can fix almost anything if i know whats wrong BUT i have no idea where to start on this. I have a 1966 f250 custom cab and the blower motor does not work. I just went through a nightmare of a time trying to hook up the cluster.
the truck runs well and reaches operating temp so i will diagnose the heater core later but for now thats not the issue.
the headlights and tail lights work but no turn or brake lights so possibly related?
the radio, cabover lights, and heater do not work.
there is a **** that says heat, one that says fan- off/high/low and one that you pull to change from heat to defrost. The heat/ defrost **** is a mechanical linkage so is likely not
My question is where to go. Electrical is my weakness. Is there a common fail point? I cant find a wiring diagram that has any info on the blower motor or *****.
its 8 degrees outside so im trying to figure out what online before i head outside to dig into it.
any help is appriciated thank you!

One thing to look at generally is the large electrical pin block connectors through the firewall, these will be corroded all to hell unless somebody has given them some special attention. Try a brass bore brush and kerosene.
