The wife's 68 Barracuda's wipers just stopped working. I replaced the switch with one I think is good. It was on my parts shelf so who knows if it is good. How do I trouble shoot this? If wifey ain't happy no one is!
If any upgrades was made the whipper motor has a ballast/fuse under the hood I think, but like 1968FormulaS340 said it could be a connection in you bulk head going to the fuse box, I would think there is a fused link somewhere, but I could be wrong. a test light would be my best friend if I had this problem...... I don't have any info on a 68 Barracuda for a wiring diagram ... is there one here some where we can share ?
If they had not been used for a long period of time. Turn the wipers on and tap the wiper motor with the handle end of a screw driver a few times. The brushes sometimes "freeze up" and tapping the motor while in the "on position" will make enough electrical contact to get them going.
