Hello, in reading all the comments, i am not clear as to how to access the Wiper linkage to see if the Bushings are ok, my arm that connects to the drive arm has come off , i reinstalled the ne bushing and and new clip retainer, but it moves turns a couple of times and the clip gets knocked off, do i have to remove the dash to see if the other linkage bushings are ok?, any help would be appreciated, thanks, Nick
