2003 Chevy Cavalier - Driver side wiper doesn't work

How To Install Replace Wiper Motor Arm Chevy Venture Pontiac Montana 97...

I'm not sure if this video does apply to the 2003. All the linkage can be removed from under the cowl.

If it were the motor neither side would move. Chances are its the linkage.
You'll probably need to remove the panel under the windshield to access the linkage and check it out.

take old one into part store or dealership get new one and replace it .
this part gets installed in hole first then u pop it back on the ball shaft

If one works the motor is ok. The issue is morre than likley the linkage under the crowel below the windsheild. it has com apart or the wiper transmission is bad. Try accessing that arrea to get a look. you will probably see the control arm just lying on the bottom, possably along with the nut that fell off the back of the transmission.

need to check linkage for the wiper arm under the cowel between hood and windshield

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/joseph_f4ed739f62995525

linkage

There is a linkage that connects the driver side and passenger side wipers so they can work in tandem. That linkage has either broken or come loose at the driver side wiper or the passenger side wiper. Check this link to see how wipers operate and then you can examine yours to see where the problem exists.

hi, im not sure if they would have a separate motor each because most vehicles have a linkage bar that connects the two wipers to keep them in time with each other. without the wipers on, try manually rotating the paasenger side wiper (be gentle) if that moves easily and the drivers side does not even flinch, then it could be a broken linkage. hope i helped!

check the tension on the wiper arm itself...there is a 12mm locknut that will go lose and it being lose will cause the arm to slip on the shaft...there is a cover on that wiper arm hiding that nut

you need to remove both the wiper arms. Take off the rain seal from under the windshield. remove the cover underneath you will find the rod has worn and dropped off you must get a complete new mechanism. Or if you cant afford to do that re attatch the rod to the buckle pin on the wiper arm and use some insulation tape to make a temporary repair till you can get a new one.
