AC/Blower Motor Problem
When I switch on my heater or even my vent in my 76 nothing happens. My AC Compressor is on the floor right now (seized up) but that shouldn't have anything to do with it. I have replaced the relay going to the blower motor but that did no good. (I thought that was the problem because I have juice going into the relay but nothing coming out of the relay to the motor) I am trying to track down a wiring diagram for it. Does anyone know where to find one or perhaps where I should be looking for the problem. I am leaning toward the blower motor myself.

You need a good year-specific wiring diagram. The relay has 12v to it for fan high speed. You can check the blower motor by connecting the terminal directly to 12v and see if it works. Is the fuse in the fuse panel good? Could be the fan switch, could be a disconnected wire. You just need to get a diagram and trace it out.

Doc Rebuild has put out some great wiring diagrams recently.
I was at his place a couple of days ago and saw them in person
They are 11"X17" and they are laminated.
These things are very precise and very easy to read.
Worth every bit of $12 each.
