i have a 1966 mustang and the wiper blades cant get them off. i spin the knob and nothing. i just want them off.

Sounds like you need a switch, Pull a fuse till you get it fixed just hope it don't rain and if it does put the fuse back in. Get a switch should fix it though. JMO..........Cole

I don't know about Mustangs, but my 62 Pontiac used to do that...There is a little cam in the gearbox that would stick........the cam needed to go around to the home position to shut off,.....needed lubrication.

The park cam came to mind when I read it, could be what it is.

Until you can get the correct fix you can do this. In place of the fuse hook up a switch so you can turn the wipers on and off, put the correct fuse in line with the switch. Make sure you get a switch that can handle the power to the wiper motor.

First I'd check the park function, as mentioned twice above. If OK, it's very likely the switch.

There is power supplied to the wiper motor at all times.

grounding the leads is what makes the wiper go

If not a "park" issue----as I do not recall my 65 having a park feature like the chevies do----it would seem the wirper switch has grounded to itself inside the switch.

the switch should be grounded to the dash and the knob switches the
ground leads from the wiper motor to the body of the wiper switch that is
electrically connected to the dash

In the op's case, the "Park" I'm talking about is the circuitry and switch integral w/the wiper motor that causes the wipers to stop only at the bottom of the windshield when the switch is turned off.
