Troopy wiper arm question

[PhillipJFrye]

So my passenger side wiper seems to not be putting enough down pressure on the blade. It loses contact with the windshield in the center part for much of the stroke. The arm seems to be working close to or the same as its brother... the spring exerts pressure and nothing seems too out of whack. brand new bosch icon blades (and this began happening a month ago with the old blades).

Anyone have this happen? Need to pick up a new arm or might there be a simpler fix? Any suggestions welcome. Thanks.

Your wiper spring inside the arm is worn out, and the arm is not pushing down hard enough. OR there is some crap in the hinge area keeping it slightly propped up.

kind of what if figured... the hiccup is that i can't find that spring for sale on an oem website. only the whole arm is for sale. if it's some kind of standard sized spring that i could get on amazon, i'm all ears. or if there's some other option. thanks for the reply.

Speccing out springs is such a pain. I've never really been successful, even using the Machinist Handbook for the math tables.

What I do now is go to Ace Hardware. The good ones have assortments of hundreds of different springs. Then I try to pick a close one.

Or you could just get new arms. They are only like $40.

yeah, might be headed that way (replace the whole arm). I've replaced so many parts now that one more bit seems like par for the course. after all, the arms i have are 23 years old now.

May also be that style blade is just too stiff.

Update: pulled off the problem wiper arm and saw the round metal doohickey the arm plugs into has rotted away, giving play to a mechanism that shouldn't have any, therefore lack of wiper pressure on the windshield. pulling the trigger on a whole new mechanism, minus the motor.
