Yeah, that's likely what will happen. With our Suburban that I mentioned, we had it in twice for the bizarre wiper action that we saw...but never happened when the service guys would sit there trying it. That was until the 2nd time I actually took it, they couldn't duplicate, and 2 miles up the road when it was sprinkling...off nutty they went again. I called, turned right around, and they saw and ordered the part.

It's a hard to diagnose thing, because it's intermittent.

At least you're not letting it complete mar your view of the car, as some morons would. Is this particular car the "one" you're looking to buy?
