Wiper Motor - Park Position
Posted: Mon Jan 22, 2024 9:54 am
Even though there are a number of threads on wipers I thought I would start one on "Park" position to aid in search.
Have seen "Park" wire and the word park mentioned in other threads ...
Down to the horn (wiring in column) and wipers on a frame-off restoration of a 68 W200. I have a mechanically restored/running 1967 W100 to refer to/reference.
Replaced all wiring (except in the steering column tube) with a Painless system.
Using the original wiper motor. Bought a new old stock switch and circuit breaker. Wipers/switch are wired for key off. Wipers work at variable speeds when switch is turned on and the wiper movement range is correct.
Issue - When you turn off the switch the "park" position is improper. At about 90°to proper location (points pretty close to up). The switch and motor appears to be going through the park process. IE when you turn the switch the motor continues to operate until if puts the wipers in a specific position.
I cannot find any detailed info on how to take the arm off the motor. It looks like it is pressed on. That said, am wondering if it got removed during painting (I did not paint) and just got put back on in an incorrect position.
Everything appears to be working correctly on the switch and motor. It Just looks like the arm is off 90°.Have a couple of spare motors (out of their trucks) to experiment with for disassembly, but no clear idea how to take the arm out of the motor.
Would be nice to not have to remove the motor, just remove arm and rotate 90°.
Even better would be if there is a setting screw/adjustment screw for "park" on the switch assembly itself.
