Ok..I just came across this board. After years off holding on to a lemon RC [love is blind], my wipers have failed, motor is fine..the little plastic 'bushing' [pn 3799089] that connects the motor shaft to the wiper link asssembly is shot. Part was easy to find, but I have had no success in removing the dang wiper arms. The service manual shows a tool. Can't find tool. I'm open to any suggestions Thanks in advance.
