Buick century 2005. my wipers no longer park properly when turned off. the action is that it seems to slow down and park in its location, but comes back to the middle of the windshield and stop. impairing my view. does it mean that i have to replace the wiper motor or is there an adjustment?
Sorry , no adjustment .
Wiper/Washer System Components
The Wiper / Washer System consists of the following components:
• Windshield wiper / washer switch
• Windshield wiper system module / motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR 25A fuse
Wiper / Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The DELAY interval is controlled through a series of resistors within the wiper / washer switch.
Park Position Operation
When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

There is a automatic park mechanism in the wiper motor, This must be damaged.

Does the wiper still make noise like it is trying to go? If so open the cap where is attached and tighten the nut on the wiper. If does not make noise you will need a wiper motor.

I found the following description on the web, this covers a bunch of the questions I was going to ask...
I own a 2000 Silo and wondered the same thing and do see some GM vans with this problem.
When I bought mine I also bought the Haynes Repair manual (1997
thru 2001 all models GM) #38036 to learn how to fix this and a LOT of
other components in/on the van.
For $20 it's worth it.
To answer your question: If the wipers stop at the position
they're in when the switch is turned off (Fail to park), disconnect the
multi-function switch electrical connector. (This is located under the
dash next to the firewall and steering column)
If the wipers now park, replace the multi-function switch. If the
wipers still do NOT park, check the wiring from the wiper motor to the
switch for a short circuit. If the circuits are good, replace the wiper
motor.
Note: There are other adjustments needed for proper operation than just bolting and new motor on.
You can have a look at this manual at any automotive parts supply store.

You could also see if the bolts holding the wipers on came loose from the snow and ice. Pop the cover off, loosen and straighten the wipers where they should be and tighten.
