ok, i'm installing 4 guage wires and need to take it through the hole under the wiper cowl. i couldn't find a drill bit big enough to enlarge the hole i already drilled (it's an old drill and i don't have a complete bit set). so i tried to take the wipers off today and they wouldn't come off. i took the bolt off. is there a trick to this? do i just pull as hard as i can? any help with this i'd appriciate. i was just affraid to rip the damn things off.
