I have a Chevy Impala 01 and my wipers dont move at all anymore. I can hear and see that the motor is working and turning.A alley mechanic told me its was stripped and needed to be fixed, but how?
Gm vehicle have a break away feature. Its intended use is if the wipers are frozen to the windshield and you turn on the wipers it wont burn up the wiper motor or break the linkage. Often times they will disengage on their own. Try moving the wiper back and forth by hand and see if it locks back in. If that does not fix it, the linkage has likely popped loose and you will have to remove the cowl in order to either put the linkage back together or tighten the nut on the end of the wiper linkage at the wiper motor where it is slipping. These are the most common wiper linkage problems on your model
My Subaru doesn't have a fluted stem on the wiper spindle, and when the nut came loose, it wouldn't move. There is a cap on the base of the wiper arm. Pop it off and check the nut under the cap to see if it is tight.
turn wipers of/lift up end of wiper arm (there is a little cap at end by windshield) take 13 mm wrench and tighten the nut that you see there/do other side and then turn them on
