I have a 1995 Grand Prix, 179,000 kms. Recently the cruise control stopped working, now my signal lights work on and off. At times, they are working until I hit the brake, then they stop, and I need to turn them off and back on again to get them to work. My automatic headlights quit working as well a few years back, same scenario, as soon as I hit the brake, they went off. My mechanice replaced the flasher and checked the connections, what is the next step?
