Had my passenger wiper blade stop moving last night, took off the cowl and found that it had come off the linkage arm. Popped it back into the little nylon/plastic ball joint clip, but I'm thinking its going to come off again at some point. Anyone know if they sell just the little plastic joint clip, or if I have to replace the linkage arm, or if I have to do the whole transmission for it? I don't mind spending the cash to fix it, but don't want to replace a perfectly good wiper transmission for what looks like a 25 cent plastic part.

 

I gather the individual part is not available - but check out this link on a repair:
