97 MGM. My drivers side windshield wiper skips across the windshield. The passenger side does not do this. I have replaced the wipers a few times, and it still skips. It doesn't skip as badly if I am stationary, but if I am going down the road, it gets progressively worse as my speed goes up. Any suggestions?

Check your wiper arm. They can get bent/twisted and not hold the wiper at the proper 90* to the windshield, which will cause them to skip. Mine usually end up twisted after the winter from moving the snow. Easy enough to fix, just twist them back until the wiper looks like its at 90* to the glass.

Another thing, the springs in the wiper arm that hold the wipers on the glass does get weaker with age. This can be compensated for to an extent by bending the arm. Eventually tho, it just becomes nessesary to replace them.

Exactly what BigMerc said, I had to do the same thing to my driver side arm the other day. Happy to report, no more skipping.

I had the same problem, same side on my 1996 MGM. Replaced the wiper arm (about $20) and it's much better, but still not 100%. I think that's about all I can do, though.

I've had perpetual wiper problems on every car I've ever owned (no kidding). You can try any and all of the following, mostly in the order below.

1. Clean windshield with acetone, paint thinner, ammonia, vinegar, or some other concoction. Probably won't stop the chatter.

2. Clean windshield with Bon Ami or some other non-scratch cleanser. This removes surface contaminants that chemicals won't touch. You know you're done when water sheets off the glass, not beads.

3. Try different wiper blades. Some brands work better than others, depending on the design of the blade and shape of the glass. My '03 CVPI skipped until I installed OEM Motorcraft wipers, though I think I got lucky.

4. Buff windshield with glass compound. Might not work if the glass is heavily etched. Makes a mess, too.

5. Bend wiper arms as described above. You want the angle of the blade to switch direction when the arm changes direction.

6. Install new wiper arms (or new arm springs) as described above. The greater the force on the blade, the less likely it'll skip -- though there is a point when too much force is a bad thing.

7. Check wiper linkage bushings and replace linkage if necessary. Sometimes, the bushings will get sloppy and the excess play causes chatter as the wiper moves across the windshield.

8. Replace windshield. Years of wear and tear can etch the glass and make the surface almost sticky, causing chatter.

9. Replace car. Seriously. I did this with a Cadillac Eldorado one time because I couldn't take it any longer.

Oh, and don't ever use Rain-X or wax on your windshield. You'd think the slippery surface would alleviate wiper chatter, but it makes the problem worse (though I believe it largely depends on the vehicle and geometry of the wiper system, as some people don't have a problem). Put that stuff on and you'll be starting over at step #1 above.

Goooood luck! I hope you fix your problem, though I don't envy you. smile

Humm, I've been using the Rain X wiper fluid in the fluid tank. The orange stuff. I'll try to bend it a bit and see if it works better. Are new arms expensive?

Got the same problem with my driver's side wiper arm. Tried bending it, but I'm going to have to replace it. The passenger side will probably follow soon after, so I'll replace them as a pair.

The wiper arms are usually about $20 each, not too bad.

Where can I find wiper linkage bushings? Mine have a ton of play, and that might be whats contributing to my problem...Maybe the rainx too.

Perhaps I'll just go get a new wiper arm. Are they hard to replace?

Nah. Just open the hood, lift up on the arm, there will be a little tab where the arm hooks to. Pull it out as far as it will go. Pull the arm off. It might be a bit of a pain. Then reverse to reinstall.

Perhaps I should take comfort in knowing others are having this same problem - even with new blades. Somehow, it just doesn't make me feel any better.

Make sure your buy motorcraft wiper arms.

It may sound trivial but the aftermarket ones don't last very long. Mine didn't even last 6 months before the springs failed again.
