My 2003 Impala wipers park in the far left position, instead of down next to the cowl where they are supposed to. I recently turned the engine off while they were part way through a cycle. When I started the car next time, they started again but when I manually turned them off, they started to park and then went all the way to the left of the windshield and stopped. Everything else works on them, including the delay, but they always park in the far left position. I even tried pulling the fuse and reinserting it, but no good. Any clues?
The problem could be a bent parking pall bracket. This is usually caused when you wipe snow from windshield using the wipers instead of brushing off. You need to remove both wipers and the cover from the drivers side. Remove the cover over the wiper motor assembly (held by a plastic button). On the right side of the wiper mechanism is a small tab (part of the wiper bracket). This tab needs to be straight for the wiper park pall to rest against.Carefully hammer this tab straight (or you may have to replace bracket, big job) Then cycle the wiper and you will see the assembly return to park position. Re-install all parts in reverse order.
Hope this works for you.
Windshield wiper arms are about to loose shaft teeth. Each arm is holded by a 1/2 " nut. Loose it and take them out. Check for damages, usually on the windshield wiper arms, the shaft is designed to last longer. When replace the arms, make sure to instal it on the right off position. I had similar problem before and this solved the problem.

Hey Derek , here is how the wipers park position is suppose to work !
Windshield wiper motor park operation is controlled by the body control module (BCM) using an input from the park switch within the wiper motor assembly. The BCM monitors the windshield wiper motor park switch circuit to determine if the windshield wiper blades are at the bottom of the glass. The circuit will be pulled to ground by the wiper motor park switch while the windshield wiper motor is operating. When the wiper switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the BCM will continue to operate the 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 BCM will park the wipers the next time the ignition is turned ON.
The wipers will not park when they are commanded ON and OFF with a scan tool. The BCM will park the wipers the next time the wiper switch is turned ON and OFF.
The BCM provides stall protection for the wiper motor by monitoring the park switch. If the park switch does not transition for 3 seconds while the wipers are operating, the BCM will assume that the wiper motor is stalled, and will de-energize the wiper relay until the wiper switch is cycled OFF and ON again.
Check for a voltage signal on the yellow wire at the wiper motor assembly , this is signal to the BCM ! If there is no signal you need to replace the windshield wiper motor assembly ? If there is a signal need to have Tech 2 scan tool hooked up to see if The BCM is the problem ! Relay #39 an #40 are the high an low wiper relays in the under hood fuse block ! Do you have a volt meter ,do you know how to do electrical testing ?
At the base of the wiper arm there is a plastic cap,pop this off ,underneath there is a nut that holds the arm in place ,if it gets loose the post will turn inside the blade.Just turn the wipers off and tighten the nuts with the blade in the parked position.
remove the cowl under the windshield and remove the wiper arms which holds the blades on. remove the motor and put the new one in. be careful the wipers are in the correct position as the were before or they may not park
Your windshield arm is in need of repositioning. Take off the cap on the windshield arm and loosen the nut under the cap. Reposition the arm so that it faces 180 degrees flat to the passenger side of the car. Tighten the nut. This should solve the problem you've described.

I've fixed this problem before. You have to disconnect the wiper transmission from the wiper motor. Put wipers in off position, unbolt the plate on top of wiper, turn wipers on then off. In the off position see where the wiper transmission is position in relation to where the park position is, remove the top plate from wiper motor and position it so as to be able to reconnect the wiper transmission now in the proper place. Please keep me informed. thanks you
I just solved this problem last night with my '05 Impala, and ultimately the solution was what newton5083 stated above. Yet, it may also be this (I found it online somewhere):
You have bent or broken the "park tab" on the windshield wiper motor bracket. The correct way to fix this is to remove the wiper arms, wiper linkage and wiper motor from the wiper motor bracket, and install a new bracket. I just bent the tab back into place a couple times for our daughters 2005 Impala but it kept getting bent down again when they didn't take the time to make sure the wipers were not frozen to the windshield, or tried running the wipers to remove heavy snow on the windshield. So yesterday I fabricated a small piece of metal and bolted that to the bracket in the same place the tab stop was. If someone wants to access this bracket and tab- 1. Use a ½ inch or 13mm socket & ratchet or wrench to remove nuts on wiper arms. 2. They may make a special tool to remove the arms, I used a screwdriver and hammer to tap bottom of the arm to wedge them apart from the spindle. 3. Two small button-looking clips hold the drivers side cowl cover in place under the windshield. These are two-piece clips, pry up the center, than the outer piece. 4. Unclip the washer hose from cowl cover, than pull out plastic cover. 5. There is a smaller plastic cover with on plastic button head holding that cover in place. Gently pry under that clip to remove that cover. 6. Now you can see the wiper trans and bracket. You should see a small tab on that bracket that looks pushed down and bent or possible a square small hole with some torn off metal where the tab broke off. 7. Remove small plastic cover over the wiper transmission and you can see a small spring-loaded arm underneath the wiper transmission assembly. 8. You need to find something to pry that tab back up so when the wipers are running that spring loaded little arm just snaps past the tab running clockwise. It's when you shut off the wipers that the wiper transmission assembly reverses rotation counter clockwise and the small spring loaded arm underneath hits that tab stop, than the wipers will go all the way down and shut off as they should. Once that tab stop gets bent out of the way the little spring loaded arm has nothing to stop the wiper transmission assembly so it keeps traveling counter clockwise until some other stop shuts the wipers off straight up on the windshield.
There is a revised bracket part # which is supposed to be more durable, GM part #12368639. Here is a copy of the TSB which points out this problem: Bulletin No.: 05-08-43-003A Date: March 10, 2005 TECHNICAL Subject: Windshield Wipers Park in Up Position (Replace Windshield Wiper Motor Bracket) Models: 2005 Chevrolet Impala, Monte Carlo Supercede: This bulletin is being revised to make a correction to the Parts Information. Please discard Corporate Bulletin Number 05-08-43-003 (Section 08-Body and Accessories).
Condition Some customers may comment that the windshield wipers park in the out wipe (vertical) position. Cause This condition may be caused by a bent park tab on the windshield wiper motor bracket.
Correction To correct this condition, replace the wiper motor bracket. It will be necessary to transfer the following parts listed below to the new bracket. ^ Wiper transmission ^ Wiper motor crank arm ^ Wiper motor 1. Remove the windshield wiper motor drive system module. 2. Remove the windshield wiper transmission from the windshield wiper motor bracket. 3. Remove the wiper motor crank arm from the windshield wiper motor. 4. Remove the windshield wiper motor from the bracket. 5. Install the windshield wiper motor to the new bracket. 6. Install the wiper motor crank arm to the windshield wiper motor. 7. Install the windshield wiper transmission to the windshield wiper motor bracket. 8.

A TSB is not a recall, if vehicle is still under warranty the dealer should be repaired for free. If not, you'll have to pay for the repairs.
