Before servicing the vehicle, refer to the precautions in the beginning of this section.
Disconnect the battery ground cable.
Remove the wiper arms.
Remove the 8 plastic retainers and the 6 clips holding the cowl vent screens to the inner panels. Turn the retainers 1⁄4 turn counterclockwise to remove.
Remove the cowl vent screens.
Disconnect the electrical connector from the wiper motor and remove the 4 bolts that mount the module assembly to the cowl.
Remove the windshield wiper module from the vehicle.
Rotate the wiper operating arm in a clockwise direction to gain access to the bolt retaining the arm to the motor.
WARNING Always rotate the wiper operating arm in a clockwise motion or damage to the motor could occur.
Remove the nut retaining the wiper operating arm to the wiper motor.
Remove the three wiper motor-to-wiper module assembly retaining bolts and remove the motor from the vehicle.
Position the wiper motor on to the module assembly. Install the three wiper motor-to-wiper module assembly retaining bolts. Tighten the bolts to 115-151 in lbs (13-17 Nm).
Position the wiper operating arm on the wiper motor output shaft. Install the mounting nut and tighten to 22-29 ft-lbs (30-40 Nm).
Position the windshield wiper module onto the cowl. Install the mounting bolts and tighten to 106 in-lbs (12 Nm).
Connect the wiper motor electrical connector.
Position the cowl vent screens onto the inner panels. Install the 8 plastic retainers and the 6 clips holding the cowl vent screens to the inner panels. Turn the retainers 1⁄4 turn counterclockwise to install.
Install the wiper arms.
Connect the battery ground cable.
Adjust wiper arms if necessary.
Here is the picture of the motor....it is the round object in the middle of the picture that looks like a can and has a square block on the end of it.
You have to remove the cowl vent panel....just under the windshield. $64.00 for a new motor.
The left and right wiper are on the same fuse and same switch, as well as the same wiper motor. That being said- if one works and the other doesn't, the fault lies with the wiper motor itself, or with the wiper shaft (where the arm connects to the motor.)
A wiper motor has 2 output shafts that either wiper arm connects to. At the base of your left wiper arm is a small cap. (there's one on the right side too, but let it be since it is working!) Remove this and unbolt the wiper arm from the output shaft and pull outwards to remove it.
When you examine the assembly you will notice that the wiper arm and output shaft are splined, which allows the rotational movement of the output shaft to be transferred to the wiper arm. It is common for the contact area of these splines to become damaged. This is often caused by excessive drag on the wiper arm and blade. (ie running the wipers over a dry windshield, or trying to unstick a wiper blade that is frozen to the windshield)
The 1st test is to turn on the wipers and observe the now exposed wiper shaft. Does it spin at all? If it does then problem is damaged splines on the wiper arm. (the arm is made of much softer metal than the output shaft, which makes it easier to repair this problem.)
If it turns out that the splines are damaged the 1st thing to try is to clean them up a bit. I have had luck using a very sharp awl to trace the path of the splines. A locksmiths file is very useful if you need to reshape them a bit. After cleaning up the splines reattach the wiper arm and see if it works. If not the arm will need to be replaced.
Now, if you test to see if the output shaft is turning and it is motionless while the other side wipes away, then the wiper motor and assembly needs to be replaced.
When reinstalling the wiper arm do your best to make its position match the other arm. press it onto the shaft and run the wipers a bit to make sure it is where you want it before bolting it back up.
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.

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.
