I am restoring my Barracuda and cannot pull the headlight knob from the dash to either the parking light or the full on position. It does not budge. Since I can't remove the knob and the stem, I cannot remove the switch body from behind the dash. I have tried reaching behind the dash to push the button on the switch yet that had no effect. The knob turns freely and smoothly clockwise and counter clockwise but will not pull out. It does not feel like a frozen switch but when I try to pull it out from the dash, it does not budge. What am I doing wrong? Any suggestions or alternatives for replacing the switch?
