1974 Ford F100 heater blower
 

The blower quit working today and I can't seem to locate the problem.Fuse is good and I have'nt used it since last week.It was working fine when I parked it in the garage:-huh.Anyone with ideas.thanks for your help.

Switches can go bad , use a jumper wire to go around it , if it runs , then that means the switch needs to be replaced.:)
