Electric Wiper Motor & Switch questions

[jmooner3]

Guys - I've read a bunch of good info on the wiper motors but I'm confused what is wrong with mine.

Got it cleaned up and working. The motor runs continuously regardless of switch position. I have the three wire (plus power feed) two speed switch.

The contacts on the motor do open for the "park" circuit. Not sure what the electrical function should be in the motor or the switch.

If anyone has one to check or knows I'd appreciate the tip. Not sure which one to chase at this point.

First the switch ohming across the pwr feed to each the Green, Red, and black wires shows me this:

Hot to Green : full clock wise- 0 ohm, Mid position-0ohm, full counter clock- open

Hot to Red :full clock wise- Open, Mid position-0 ohm, full counter clock- open = provides low speed?

Hot to Black : all 0 ohms...should hot to black go open at full cc position to shut down or park?

As for the motor itself

resistance across connections internally:

Green to black short

Red to green short with park contacts closed and 1.5 ohms with contacts open

Red to black 1.6 ohms with park contacts open or closed

Any help or suggestions welcome.

Thank you!

Anyone have electric wiper knowledge?

B, F, and A. On mine green goes to B, yellow to F and black to A. When looking directly at the motor arms and you shut the motor off with the switch they should park at 4 and 8 o'clock.

red goes to F if you don't have a yellow.

Thank you GTK! You solved another one. Previous owner had had Black and green reversed. As you stated green goes to B, White on mine to F and black to A.

Wiper motor switch hook up on a 1952 Dodge B3 truck, I have the green,white and black wires on my wiper motor. On the switch, I can find no markings that say B,F,A. Does someone have any idea which terminal is A,F,B?

Thanks,

Any one have 1 extra clip that holds the wiper arm to the pivot point on the vacuum motor? I lost one during my happening where the bolts fell out.
