I have a severe problem with the wiring in my 69 malibu. When I turn the key, the dummy lights for the alternator comes on and there is a click in my solenoid. I have a wire hooked straight to my starter that I have to contact to the battery to get the engine to turn over. However the car will not crank unless the ignition switch is turned. I have replaced the starter, solenoid, horn relay switch, alternator, and voltage regulator but still haven't nipped the problem. The reason I replaced all the other stuff is because my horn relay button "buzzes" when I hook the battery up. I believe the culprit to this problem is my ignition key switch. My question is this: How do you go about replacing the key switch in a 1969 malibu 307 automatic? Any help would be greatly appreciated!!!!!!
