So I finally have gotten around to fixing the wiring on my 59 1 ton to have wipers (good to have this time of year. I install the new driver's side wiper in the down position and turn on the motor and the blade tries to move further down. I reinstall the blade in the fully up position and turn on the motor and the wiper sweeps correctly. The passenger side is just the opposite, the blade parks in the down position. Under the dash, the driver's arm attaches to the top of the motor and the passenger side arm attaches to the bottom of the motor. Any guesses why the driver's side wants to park in the up position?

cuz that's where you put it? you have the wiper arm on in the wrong place - you should take both wiper arms off [outside, inside they're called transmission links], run the motor and stop it to park the shafts, put the arms/blades on in the parked position [both down to the outside] if that don't work you have the tranmission links hooked to the wrong pegs, but that's not likely, I don't think they'll fit opposite - don't forget the little springy doober that clips those links on to the motor framus or they'll fall off shortly! if ya don't have that, the suppliers have'em - called wiper trans arm retainer I think

I guess what I would do is take the wiper arms off, on the outside, then turn on the electric wiper and watch the action. Make sure the drivers and passenger sides are going both ways correctly. Then turn it off. Put the splined wiper blades on in the park position, and it should work.

If they are not moving right, perhaps you have the wiper arms reversed on the motor. I.E. they are moving the wrong direction.

When you start the wiper from park, the spindles should turn towards the outside of the vehicle. Otherwise, the arms are reversed.

Yeah the spindles turn in same direction when the the motor is engaged. The passenger side turns toward the outside of the vehicle but the driver's side also turns the same direction i.e. the center of the vehicle. I didn't connect the driver's side transmission arm to the motor, all I can see is that it is connected to the top of the wiper transmission. Hey red58, I didn't know the retainers were available. The passenger side link was disconnected and missing the bushing. I made a bushing out of steel rod and used a fender washer (3/16" id) and a c-clip to hold it all together. Who sells the retainers? Thanks for your replies guys.

Joe

retainers prolly every supplier - like, our sponser - part number in address
[and I see above I put it the wrong way - park is down in the middle]

"turn the same direction"?? they turn back and forth - opposite each other at the same moment
if they turn the same direction you've got something wrong! did you hook both arms to only one side of the reciprocating plate on the motor? that's all I can think would make the arms work in tandem, the same direction at the same time

got the links switched left for right? when the motor is in 'park' the driver side link goes to the lower peg on the motor, and the 2 links are different part numbers, so have some difference [which I don't remember offhand, and don't have a pair handy]

Wiper motor should have a top and bottom on its actuating arm and one wiper arm goes on each. That or have one wiper park in the up position!

Red58, now we're getting somewhere. You are sure of the arm placement on the motor. The driver's side was already attached to the top of the motor. By process of elimination I attached the passenger link to the bottom of the motor. When I wrote they turn in the same direction, I mean they both start out sweeping to the passenger side. This means the drivers wiper must park in the up position so it can sweep to the right and the passenger side wiper parks in the down position so can also sweep to the right. Clear as mud right? I will try to look at other trucks to determine if the driver's link was attached incorrectly by someone else.

well 'top and bottom' was from the assembly manual, but I crawled under the 58 and looked - the arm on the motor is actually nearly straight side to side when it's off, in parked position - in that position, the drivers link goes to the pin towards the drivers side - when the motor turns on, the arm moves so that both links are pulled towards the center - back and forth

the shape of the 2 links is definitely different as they sit under there, tho I can't see well enough to tell what the entire difference is - also there is supposed to be some difference between 5-7 and the 8/9 because they list different motors, but I have never figured out what that is

with both arms being pulled inward at the same time I really don't understand how your shafts could be turning the same direction unless maybe the links are both 'rights' or 'lefts'??
