Stuck windshield wiper

If your pivot has seized, you need to free it up and lube it thoroughly or find a good used one to replace it with. I've drilled and installed grease fittings on some of mine. For sure replace all the bushing at one time. I pull the whole wiper trans out and do it all on the bench then install it complete. Trying to install a bushing under the dash while standing on your head is a pain.....
