ok weird thing happening with my wipers. Sometimes they work too good and on there way up go and hit the A post and on the way down they hit the black plastic cover where they rest. Then sometimes they don't work good at all and they come about 5 inches from there normal position on the way up and down. What do you all think? Wiper motor? Electronics? Today I took the wiper arms off and they look ok. I looked at the connecting arm that controls the other wiper and it has some play in it. I think the motor has play in it for some reason which is causing the problem.. I don't know..
