Earlier this morning I said these fail. Actually the same thing normally fails in every one of them. Let's see how to fix it, since this switch will be infinitely better than the imported ones.
1. An overview of your switch. This is one I removed from a truck about 40 years ago and never used because it doesn't work. (first image below)
2. Press the release button on the bottom and remove the knob rod. You may have to wiggle the knob back and forth to make this happen. (no image)
3. Using a screwdriver, carefully bend up the tabs on one side only. (second image below)
4. Remove the top and contactor and the fiberglass plate below the contactor. (third image below)
5. The top of the contactor and the three bumps. (fourth image below)
6. Remove the insides (except the sliding detent rod...leave it in place as shown). Discard all the broken bakelite bits. (fifth image below)

Please jump to next post (image limitation requires this)
