I recently had my 3 speed wiper motor restored by a GREAT rebuilder (and I KNOW it is right), but when I put the assembly back together, the wiper ARMS do not park correctly. Could I have the wrong wiper transmission assembly? The car came disassembled.
With everything now assembled, and with the motor cycled once (to insure it is in park), and arms positioned on the pivots so they are properly lined up with the bottom of the windshield trim molding, when I turn on the motor, instead of going up on the windshield, the arms go DOWN around 8", then only 1/3rd of the way back up on the glass. If I position the wiper arms on the pivot half way thru the wipe arch so that they will NOT go below the molding trim while wiping, they complete a full wipe pattern, but then parks in the middle of the windshield. I think that the under dash transmission (pivot) assembly is the problem, but I don't know what since this assembly can only go in one way. Any ideas will be GREATLY appreciated

If the arm goes downward 1st in both tests then wrong/swapped linkage underneath/motor wired wrong inside it/wiring to motor skewed. EDIT does it look like if the 2 long horizonlte arms were swapped that it'd work

Make sure the link that goes from the motor to the left piviot is on the pin closest to the piviot and towards the front of the car.The link between the piviots should be connected to the pin towards the rear of the car on the left and the front of the car on the right.Also make sure the crank has P/N 2822273 (69-70 b-body only the a-body crank looks the same but is clocked different)stamped on it and when parked it is roughly at the 10 o-clock position when viewed from under the dash.You should have a nylon bushing (which is also b-body only)and a spring washer on the pin of the motor crank.

what type of car ?

I have access to a complete 1969 B-body 3 speed system if needed.

everythings still bolted to the car and theres no dash in it to obstruck the view

I can't be certain that this picture shows the linkage in the parked position or not. It may have been bumped to help with installation. Either way this is for a 68 B-body with 3 speed wiper and it works just fine. Hope the picture helps.
