My right wiper wasn't spraying well, so I replaced them.
The right wiper is still not spraying.
Are there any common problems with these?
Are there any test modes to pump fluid without running the wipers to see if I can flush the system without worrying about running the arms without blades attached?

Ish gets plugged up if you don’t use it enough. Washer fluid turns to goo. Clean it all out. Easy enough.

Well, went to replace the pump and filter, and I got the wrong pump.

Cleaned out the tank and put in the new filter and put back the old pump.

Working a whole lot better.

Yes, the openings in that filter are tiny and get plugged up very easily.
