I have been without AC and directional signals for far too many years now and I want them back.


What happened. Years ago had the shift linkage replaced at the column. When I got the truck back the AC and directional sisgnals no longer worked. The 50 amp fuse under the hood was blown. I have replaced it yet when I turn on the ignition it blows. Somewhere I've a pinched wire. SO I NEED A SCHEMATIC to trace this damn thing. I"ve got the 4.9L straight six. John

 

Sounds like you are blowing fuse "N".
More than likely you have pinched the gray wire with a yellow stripe (wire #687).
On the other hand it could be the yellow wire (wire #37).
I would also look at the Ignition Switch & its plug going to the wiring harness.
