I'm trying to remove the dash mounted switch for the rear window on my '86 Blazer. Is there a trick? I'm afraid to pry it off for fear of breaking the gizmo. It's almost impossible to snake my arm up from underneath to really push on it but I can touch it. I don't see any screws from the front. Help! The tailgate key lock has been swapped out and therefore my door key won't activate the window from the tailgate. So I want to apply continuous power to the switch without inserting the key into the ignition and have the GP's cycle off and on just to put groceries in the back.
