My wipers won't park!

[lookin@my68]

Hi all!

Can anyone help me out? My wipers don't go to the bottom of the windshield when I turn them off - they just seem to stop at a random position. Is this a fault with the wiper motor??

Anyone had the same trouble?

Is it an easy fix and am I able to repair this at home?? Oh, it's on a 68...

Thanks
Danny

the plastic gear inside motor could it be broken and loosen from the main shaft, loosing its parking position... This gear is pressure located on shaft. Is not uncommon of course along the years and engine heat.

The Main gear has at the center a notch where engages someking of parking switch with a tooth very similar to a bushing. When you turn off the wipers, the main gears tunrs in reverse and engages this bushing on the notch untill cuts the power, acting like a switch. If Gear is lost from the shaft then will loose the parking position

IMHO, I think is time to rebuilt kit or job.

Thanks Nacho!    - So are you saying a rebuild kit is available??

I think I have seen them around, don't really know where... ebay is a fact, but I'm trying to remember what dealer had them.

as far I remember, the kit consist on replace plastic gears, washers etc.., but gears have to be fit on the right location on shaft to match the crank/shaft assembly at the parking position. Maybe kit have instructions about that.

I'm not saying the fail is A FACT what I said, but is what I think.

I have not found a rebuilt kit, but just in case, if your one is 2 speeds motor:

The one pictured doesn't look right to me, it has missed some prongs and also the resistor, but maybe is just a reference pic.

I don't know if 2nd gens are the same than 3rd gens, I think not since they probably have different parking position but ask for that.

There is a park switch in the wiper motor that needs constant keyed power even when the wiper switch is in the OFF position, check to be sure it has power.

Thanks John and Nacho, I'll have to pull it apart this weekend and see if I can figure it out... If any one else is interested I found this at moparts too...

Oh Yes... that could be a reason hehehe. I don't know why allways pass over the simply.

a damaged gear could give you also oftenly an erratic movement on normal operation since friction makes brake the wipers for a while shaft is still spining. But allways is a reason to don't park good.
