84-88 Windshield Wiper Motor Rebuild. Sort of.

I found 2 of the cover units. Apparently they were made after the production runs. Assembled in Mexico. Even comes with new mounting screws.

TIP: Ensure when placing the cover back on the unit, it is in PARK position, and the cover cam is in the proper location. Also, the cover needs to have the top half sealed to the wiper motor with non-hardening sealer.

These instructions show you how to place the cam before installation. Newer style cam.

For the newer style, you want the open area wide, like in Figure 1 in the above pic. Like this.

The early OEM style has more of an arrow head look to it, and much flimsier construction. This is why it's SO EASY to break that center pin on this type. The instructions for this one says to point the tip to the bottom screw hole. Like so:

gotta bother you on this. i got a new cardone wiper unit and have my circuit board with the removable pins. my new motor has 3 pins to attach to. if youre looking at the motor i put the 2 extension clips on the 2 furthest left pins. but motor ran with no delay and no seating. i read that if motor is in park position it needs to be taken out of park position before putting the cover on?
 
Cover goes on just like I said. Motor in park and arm on the cover in the proper position. You will see the points on the circuit board where the park switch prongs would contact. That’s where they need to land. If it’s not parking than the solenoid isn’t working or the gear and pawls weren’t lined up correctly.

the solenoid is located in the cover?

There are some solenoids up on the other side of the circuit board that aren't normally seen, but no, I'm talking about the park switch.

You only see some prongs and some plastic when mounted. The business side of it shows a great big solenoid. If you flipped it upside down, you'd see this.

That’s upside down in the motor right?
 
In the gear. The other side has the spring contacts on them.

Here's the top. Look familiar?

yes sir. my motor has 3 slots to place the connectors. i am using the 2 that make contact with the cover. i may have installed the cover incorrectly. we have a storm passing at the moment, but tomorrow i will take a look. thanks again.
 
Look at post #10. It shows how the blue switch arms/rotators are supposed to be lined up before putting the cover back on. And the motor MUST be in PARK position.

So this is what I have on the motor. How can I get it to the seated position?

Your motor is obviously not in the parked position. Cover disc looks to be in a good place. Big gear is about 180 out. By all rights when you turn it off, the solenoid should This is in the parked position:

Just wondering why you replaced your motor. Was it bad? Not saying they don't die, but they're pretty robust for what they are.

Another thing that might be screwing you is a bad cover. Which there is NO aftermarket support for, nor anyone I know of that repairs them, and new ones are unobtanium. There are little relay solenoids inside that cover and all the electronic crap I have no idea about. Electrical issues are not my strong point. If it's not energizing the park solenoid, it's never going to stop. Was it doing the same thing before you changed out the motor?

You can put the cover back on the way it is in your pics because the "pin" for the rotator in the cover is in the right place. You can plug up that weird power connector lead for the unit and then run a ground wire from the case to a car ground point somewhere and test it that way. It should work the way it would in the car, without having to go through the trouble of taking it out and putting in in.

There's a troubleshooting guide in the CSM electrical manual, but it's not super-detailed. It does not go into what's happening inside the cover.

Here's the plug layout the CSM Elec manual mentions for connector 1 and 2:
