Are you referring to the blade or the wiper arm assembly? If it is the wiper arm where attaches by cowl, there is a clip underneath/bottom side that needs to be depressed before you can remove...
You can use a small blade jewlers screwdriver or an optometry (glasses) driver. You not need use alot of force..
