I'm trying to remove the wiper cowl grille so I can run wire thru the firewall. So I unscrewed all the screws holding down the grille, and removed the nuts holding the wiper blades on. But the wiper blades will not pull off the bolt. Do I need to do something else or just use more muscle? I was worried somehow messing up my perfectly working wiper motor. TIA.
