Why won’t my wiper park properly?

I just replaced the HVAC blower motor on 1992 Mercedes 300D. As you know, the monopost wiper has to be removed in order to remove the blower from its perch.

While I had the wiper assembly out of the car, I decided to re-grease the gears following instructions I found online. I even marked the position of the arms relative to the bolts. Everything is installed and the blower works, even on auto! However, my wiper won’t park properly. Any suggestions?
