The wiring for the plate lights, window break light, and rear wiper has coroded... to replace it I need to remove the rear hatch of my volvo 240 station wagon, I removed the 2 bolts that fasten the hatch to the (1 bolt each) hinges on the body and removed both of the struts that hold the hatch up... and the darn thing will still not come off the hinges! What else do I need to do to remove the hatch???
