Hello to all. I just joined this group and have a 1993 CC Concept. The passenger wiper stops to the right side of windshield and not the center. As far as I can tell it has seperate electric motor and is not linked to the driver side.

Does anyone know how to time this so it stops in center of windshield as it should?

It sounds like the crank-arm on the motor has slipped on the splined shaft.
Inspect the linkage at the motor gearbox to see if the retaining nut is loose. If it is, remove the nut and reposition the crank-arm so the wiper is where it should stop, then reinstall the crank arm, tighten the nut to the correct torque setting, which I think is 26lb/ft.
Finally, wet the glass and run the wipers a few cycles then shut off and note stop position.
If your gearbox has a flat on the shaft instead of splines, you are forced to go by the flat for positioning.

Other than the wrong parking position, does the wiper blade sweep the glass correctly?

Have you owned this coach for awhile?

Yes, the wiper works as it should. The motor assembly is very difficult to access but I did remove a panel to locate it.

1t is a 1993 concept model and I love it. I've had it for two years and drove it home to Ohio from Oregon.

The wiper motor is way up under the dash and no access from outside but I can get to it by removing a panel in front of step

Some brands of wiper assemblies had models for driver and passenger side.

So for how long has this been happening? I notice this is just your third thread.

the passenger side wiper arm broke several months ago. The support swing arm came out of its base. I reinstalled it with some epoxy to hold it and put it back on. While I was using the wipers later, I noticed when I turned off wiper switch both arms stopped but then the passenger side moved again to the middle of the glass. I could "bumb" the switch to get it to move again but cannot get both to stop in center at same time. I took arm off and played with positioning on spline shaft but when I hit the wiper switch to start, they both move toward driver side to start. Therefor, I had to put the passenger side arm all the way to right side.

What was the "Park" position of the wipers before all of this happened? At the first, you mention repairing the base mounting. Then later you mention spline adjustments. It kind of seems as though the bellcrank within the blind side has rotated 180 degrees while the "base" was loose, originally.

Thanks everyone for the input! I ended up removing the passenger side wiper motor and removing and moving the crank arm 180 degrees. After installing it back, I instlled the wiper arm in center of windshield as it should be in park position and it is OK now.
