Recently while on a trip to Iowa, my TB developed a problem in the rear wiper.

As we were driving back to where we were staying, I turned on the wiper after a monsoon hit. I noticed the wiper only going halfway, then back, then slowly getting weaker.

I pulled off at a rest area and checked it. There was (I assume) the washer fluid hose at the base that was pinched a bit, but I don't think it was related.

At one point the wipers went all the way over but couldn't go back on the return stroke, then suddenly moved further to the left off the window and down, then began "wiping" the tailgate.

I'm not sure what to check. Now the wipers don't even come off the rest that holds it.

02 TB LTZ.

I did search the forums but nothing specific to my problem appeared. Thanks.

Well I feel like an idiot...

After getting monsoons here for the last week, I actually spent a couple of minutes to inspect the wiper (as it rained) and discovered the cover of the wiper could be opened to reveal the bolt that apparently was loose. I grabbed my pliers from the back storage area and a couple of tightening turns later, my wipers are good as new.

Attached are my "in action" photos taken with my cellphone. The first shows the wiper base and bolt cover, the second is the cover flipped open to reveal the culprit, and the third is my fix for the problem.

I feel like an idiot for not doing this sooner (it's been out since June), but problem solved.

Live and learn.

Live and learn is right. We've all done some dumb stuff in our day. I bet I could top this with something more ridiculous without even having to think.:duh:

Glad you got it working.

A note about the newer rear wipers...

Make sure your kids don't use it as a pull handle. They are pressed in then a nut on top, but the nut does nothing more than keep it from falling off. I ended up prying mine loose inspecting, then cleaning and finally epoxying it back on.

What about a washer?

Should I put a lock washer on there to prevent it from coming loose again? What about a stainless steel nut?
