Troubleshoot this weird car problem

SteveDallas · 03-23-2007, 08:27 AM

I noticed recently that the driver's side windshield wiper on my car will "whip" too far to the left (your left as you are sitting in the driver's seat). I immediately assumed that some piece of the wiper assembly had worked its way loose. This turned out not to be the case.

What I've discovered is that it only happens when the car is moving! If the engine it turned off, or if it's on but idling, the wiper works fine, stopping about 3-4" from the left edge of the windshield. But if you're driving down the road, then you have the problem. (It usually gets worse with time--when you first turn the wiper on, it's OK. After a half dozen or so swipes, it's bumping into the edge. Another half dozen, and it's actually skipping over the edge.)

Any suggestions? It's kind of hard to reach out and examine the wiper blade when both the wiper and the car are in motion . . . .
