No auto park wiper motor on 68 Charger?

[gkent]

Let's get something straight first ... the switch is an absolute nightmare to get at once the dash is installed. Removing the bezel ... there's a good risk of damaging the dash pads. So, do every possible check on the motor BEFORE tackling the switch. That said, do you have the correct "3-speed" switch - it should have 4 positions: high, med, low and park ?? The correct wiper mechanism - 2 and 3 speed arm and cam on the motor are different.

Where should the dash switch be grounded? Frame? Can i run a separate ground wire from some place on the switch to a known good ground ?

What he was asking was if he added a wire from a good ground to the wiper switch, that would eliminate the switch not being grounded correctly. That way he would not have to remove the switch from the frame to check to see if it was grounded

So im having issues with the wiper motor that came on a car i bought that needed reassembly. Finally getting to the wipers…. They work fine, both speeds and off. I’ve tried without the arms on. But for some reason this motor has auto park and it never does in the same spot. After a quick picture search of 68 wiper motors, im finding out mine looks nothing like them. (See pics)

It looks exactly like the 3 speed motor in my 68 Charger. If your switch has the 3 speed detents then the only thing I see different is your park place looks to be in a different spot than mine. Mine parks properly. Loosen the screws and rotate the center piece to the left so the three hash marks are between the 9:00 screw and the knob at 11:00. See it it parks properly then.

Of course it's a 3 speed, or possibly a variable speed, just not a 68 3 speed!

It looks to be the same 3 speed that came on my 68 Charger.

OK, loosened all screws couldn’t budge it so I took a screwdriver and started tapping one of the three bumps counterclockwise to get it close to the position that you have. See the picture below, that’s as far as I could get it to move. It would not go any further. Tighten the screws jumped inside the car turn the switch on All three speeds work but now does not park at all. The only thing it does is wherever I turn to switch off it stops right there. I will say I noticed when I turned it on the first time on low speed, It went supersonic fast until I touched the switch again and then the slow speed came back. This has done that a couple of times.
I also removed the ground strap from one of the mounting studs and the face of the wiper motor cleaned all nuts washers, and the strap itself for a better ground

Pulled cover off and gently cleaned the contacts. Put back together, same thing, now parks in same spot. Next up - try again with wiper arms attached. Fingers crossed they don’t drop down onto cowl grill again

you can mark your wiper arm posts using a sharpy, and maybe you can then observe if the parking is working to your satisfaction before putting the arms back on.

Lol!!! That’s exactly what Ive been doing!!! It parks in same spot every time, with no arms on. Once wiper arms are installed…. Wipers drop to low onto cowl grill, and park 1/2 way up the glass….. and before im asked- yes… i installed arms in proper stopped position!
Thanks for your input!!!

When you had it apart, did you notice any of the plastic gears stripped or any evidence of broken parts? If not, it should park in the right place if adjusted properly. Then install the wiper arms. If that don't work, I wonder if the wires are all hooked properly on the switch.

What i had apart, was the “cover”? Of what i thought was the park contacts? See picture, there were no gears in there, which is as strange to me since the inside had gear teeth around the entire perimeter?
