Wipers were on and then all of a sudden the driver's side stopped. The passenger side works fine as well as both sides washers. I can move the driver side up and down with no resistance. When I turn the wipers on the passenger side works fine, however the drivers side doesn't work at all. You can see it move about a 1/2" up and down while the passenger side is fine.
Do you
have the same problem?

Welcome to 2CarPros.

A few things may have happened. The wiper arm may have come loose, stripped, or there is a problem with the linkage.

What I want you to do is first, confirm the nut holding the arm to the wiper transmission is tight. If it is, remove the wiper arm. Here are the directions for removal. The attached pics correlate with the directions. Also, you will see how to access the nut to confirm it is tight. Once you remove the arm, check it to see if it is stripped where it mounts on the transmission. Also, if it isn't stripped, with the wiper arm off, turn on the wipers and see if the transmission is moving.

WIPER ARM REPLACEMENT
REMOVAL PROCEDURE

picture 1

1. Mark the wiper park position on the windshield with a suitable non-permanent marker.
2. Remove the cover from the wiper arm nut.
3. Remove the wiper arm retaining nut.

Picture 2

4. Remove the wiper arm from the wiper transmission drive shaft.

_______________________________

If the transmission doesn't move with the arm off and wipers on the linkage under the cowl at the base of the windshield may have come off. The wiper motor is mounted on the firewall under the hood. When on, it turns the linkage which is attached to each wiper. There is a ball joint connection at each side. See pic 3. It shows the joint being removed with a special tool. That may have come apart.

Let me know what you find so I can better help. Also, I will tell you that often times the wiper arm strips and needs replaced. You will know once it is removed. Regardless, I'm hoping it just came loose.

Take care and let me know if you have questions.

I found the wiper arm lock nut only finger tight. I took it off and check the spline (it's a little worn), put arm back on and tightened it really good. It seems to work fine now. If the spline/wiper arm gets to worn I'll have to replace them. I'm not sure if the spline that's connected to the linkage is a replaceable part or not.
Thanks for your help.

Welcome back, Dave.

The spline itself isn't replaceable, but all you will need is the spline and what it is attached to under the cowl. The linkage is removable, so you could get one at a salvage yard if needed.

Regardless, I'm glad you got it going.

Take care and let us know if you have questions in the future.

I have had the same problem as many other s10 owners have had, where the wipers used to work (intermittently), now they dont work at all. I have replaced the connector to the motor and it worked great, very briefly. I read on some forums to re-solder some of the connections on the board. I did them all, and still nothing. Please help. 98, 4.3l, 2wd

Have you considered replacing the pulse board? I have seen two Blazers with similar problem, and the pulse board replacement cured the problem.

Available at your local parts store, Dorman 88136 retails for about $30.

It is quite possible. Here is the diagnostic for your problem and the wiring diagram.

That sounds like the problem. Honestly, you'll end up paying 25 bucks at a junk yard. I would spend the extra and get a life time warranty if possible. As far as replacement, it takes a little time, but if you have some mechanical ability and tools, you could most likely do it yourself.

Let me know what you decide.

I turned the wipers on when they were frozen (winter time) and they didn't move. The next time I turned them on the passenger side worked but the drivers side wiper went all the way to the left, sticking out towards the side mirror. I had to pull over and push it back down, now it will not work at all. The passenger side still works.

Hello ehesenflow

The wiper motor is most likely the problem, but to make sure the wiper linkage is not loose from the wiper transmission, it must be removed:

Disconnect the negative battery cable.

Remove the cowl vent grille and screen retainers

Remove the cowl vent grille and screen from the vehicle

Unfasten the wiper motor retainers


http://www.2carpros.com/forum/automotive_pictures/46384_5_1.jpg



Installation

Install the controller on the wiper motor and attach the motor wiring harness to the controller.
Place the wiper motor in position and install the two retaining screws. Do not tighten the screws until the wiper motor shaft is centered in the tailgate hole. Once the shaft is centered, tighten the screws to 57 inch lbs. (6.5 Nm).
Attach the wiper motor electrical connection, then install the end gate trim panel.
Install the spacer and nut onto the shaft and tighten the nut to 53 inch lbs. (6 Nm).
Install the wiper arm assembly and connect the negative battery cable. Check for proper motor operation.

I don't know about a warranty but I do know that the ground on the wiper motor sometimes corrodes causing the wiper to fail. Check it and clean it.
