Horns were not working, checked fuse, relay, replaced horns. Now horns go off continuously. Tried folded piece of cardboard slipped under top of steering wheel cover didn't work. So I figure the bushings in the frame are shot. I have a 99 boxster base used a T27 torx wrench to get screws loose. worked on one wont work on the other one. I got a feeling the head is stripped. If I try to tighten the screw the wrench seems to get a good bite on it but to loosen nada. Does anyone have any ideas how I can get that other screw out? Should I try to drill it out? Should I just take it to the garage and let them deal with it?
