I'm going to replace the cowl panel grommets since they have been leaking. Got the passenger side of the panel off, but the drivers side is trapped behind the wiper arms. I took the rubber caps off, took the nuts off, but the wiper arms are stuck on there good. I've sprayed it with PB Blaster twice and used a wiper arm puller which started to bend without the arms so much as budging. Now what?
