I removed the wiper blade arms to remove and repair the windshield cowl/trim. And now I can’t figure out which arm is left and right. I’ve searched online and surprisingly can’t find any info on this. I’ve gathered there’s a 1” difference between the blades but they are all sold as sets so I haven’t been able figure by blade size either.

The difference is is at the lower end of the windshield as the top end both go to the same length. But also I don’t know if the arm designs have subtle differences?

I have bayonet style attachment.

Thanks.

I think I figured it out. Looks like arm ending in CC, which has 18” blade, is driver’s side. And arm ending in CP, which has 19” blade, is passenger’s side.

Regarding the issue of the 19” passenger’s side blade overhanging at the outer edge, this will not be remedied by installing an 18” blade because the extra length is on the inner end of the blade, not the outer end. Not sure if there’s a solution in perhaps non-OEM blades. If anyone knows, I’d love to know.

Thanks.
