When the driver side wiper is in motion the arm reaches too far to the left and get stuck or arm connection under the windshield that look like a ball in socket dislocates when driving in the rain. causing poor visibility.
One of the windshield wipers stopped working. it moves up a 1/2 inch then moves back down. won't go any higher than that. happed out of nowhere and the other works perfectly fine. it looks like a bolt or something is loose.
Heavy rain last 2 days.. turned on wipers and the driver side wiper failed to complete its course, causing the passenger side wipe to "run over" the driver side one. the passenger side wiper then became entangled with the "stuck" driver side wiper and actually caused it to flip up and over, thus rendering both wipers useless and me unable to see where i was driving during a heavy rainy / foggy night! i managed to pull into a plaza safely to flip my passenger side back to its proper position. when i checked the driver side wiper the complete arm that attached to the motor was loose and it would not stay in the correct "starting / finishing" positions and i could push/pull it up and down into different positions but after one wipe it would bottom out on the bottom of my windshield/cowl back into the incorrect position where it interferes with the passenger side wiper. this is a very serious safety concern as i could not see where i was going and now my wipers are useless because even if i use it for a single wipe it gets ass tangled up. see the attached image of the passenger wiper that is flipped upside down from normal use during heavy rain! i used to install these wiper assembly at gm and i know for a fact that this one is not torqued to specs because i can move it by hand! and the wiper blades are likely eaten up now too from cleaning on and off the glass, onto to cowl and over top each other. not to mention the bolt that attaches it to the motor is likely stripped up now from the free spinning movements....
