98 ML320 Wiper problem
 

Please give me some advise. My wiper linkage seized. I changed new wiper linkage. now the wiper stop in the middle. is there a special way to set up the wiper linkage

I suspect the arm that attaches to the wiper motor shaft is incorrectly installed, it needs to go back on the same way it came off the old motor, which is kind of tricky as the arm is directly over the nut. Sometimes the new motor is received in the "non-parked" position, so even if you think you did it right, it's still wrong.
