I removed the headlight switch without a problem, but now that it is time to get the dash back in; I can't get the switch back together. The rod just goes in and comes back out. Nothing holds the rod in the swtich. Am I doing something wrong? I first tried sliding the knob and rod into the switch...I then tried pushing the button and sliding it in, but nothing works. I even tried a different switch and got similar results. Help me please!
