Hi guy me again, I purchased new wiper arms and blades for my MGM my old arms were rusted and not applying enough pressure to the wiper blades.
Even with my old arms and blades my passenger side arm and blade assembly does not seem to park in the correct posistion. the drivers side seems to park just fine. ( yet I am not 100 percent sure )
My wiper motor seems to operate properly when i turn them on, when I shut them off the blades stop and then go down towrds the leaf screen stop ramp as it is labeled in Mitchell I call it the plastic cowling.
When the motor is parked the drivers blade is low and parallel with the edge of the plastic cowling ( leaf screen stop ramp ) the passenger side seems to park at a angle with some of the blade on the ramp and the rest on the windshield at an angle to the plastic cowling if that makes sense.
The Wiper arms have a built in key so they cannot be adjusted to the pivot shafts. ( meaning they only go on one way )
I looked up in Mitchell on demand diy for any information I could find on the wiper arm and linkage - transmission assembly
They show a possible adjustment which is baffeling me I will type word for word what is printed about the adjustment.
1 Wiper arms are keyed to pivot shafts, adjustment of park posistion is not generally required. However if park posistion is not correct inspect linkage for damage or disconnection.
( I did pull and clean up all the leaves and debris from under the plastic cowling hoping binding on some debris was preventing a true park posistion yet nothing changed and I did not see anything damaged or bent pictures attached ).
2. If linkage is okay remove wiper arms from pivot shafts. Remove plastic key from pivot shaft(s) Turn on wipers. Allow motor to cycle pivot shafts 2 or 3 times turn off wipers
and pivot shafts to return to park posistion.
3. Reinstall wiper arms in proper posistions Diamension X should be as specified See Figure 1 Wiper Blade Adjustment Specifications table
Picture of diagram also attached
Now what pisses me off there is no diagram or instruction on how to remove this plastic key or even mention where it is at on the pivot shaft.
Then they do not mention reinstalling the plastic key once the operation is complete. WTF is it me or are these people complete lazy aholes?
So my question is where are these mystery plastic keys and how do I remove them?
Second with my pictures provided can anyone see a bent linkage that I am not seeing?
Thanks for any help with this.
I am so glad I signed up for a Service manual subscription so I can fix things on my car without guessing LOL
BTW my guess is that the motor is not retracting all the way to the park posisiton if this is the case I am also to assume the wiper blades should be parked on the plastic cowling which would make the drivers side off as well.
With this in mind a clear picture of where properly working and parking wiper blades should be when parked for the 2000 MGM would be very cool thing for someone to post here.
Thanks inadvance for any help with this.
I plan on trying to source a new plastic cowling since mine is deformed and will wreck the blades if they have to drag across them to get to park posistion if I cannot find one I will try and reshape it with a heat gun.
