Ref. 75 F-150 w/ a.c....A dumb question; Where is the fuse? If it's ok or a new fuse dose not make
it work, I'll check the wire. This happened once before in 1974 on a 67
Olds 98 equipped with Comfortron....automatic a.c. It was a circuit board. To make the blower work, I wired it to the rear window blower.
