See where the play is. If there is a nut on the shaft, tighten it. If not, then maybe in the linkage somewhere.
What u need is Gibbs oil, it goes way beyond all other liquid wrench, wd40 stuff.thanks ranger. i did just that today and it def helped. underlying problem is still there.
im pretty much positive you are right about the linkage being loose somewhere. i spent HOURS today trying to get the driver side arm off. my god, that bolt is like double rusted on, and bent, gave up when the sun went down.
its so sad, im so close to fixing yet so far away... ive taken the arm off before no problem. just lift it off and done! but man, the old age is keeping it on. i managed to budge it enough so i can rotate the arm freely, but i cant get it clear off to save my life. sprayed some liquid wrench on it to try to loosen it up. may have to get at it with a hammer to unbend it tomorrow so i can lift 'er up and get at that linkage.
my whole wiper system is all sorts of messed up! you dont know what you got til its gone...
thanks. ill let you know what i find
