petelempert Posted September 26, 2013 Share Posted September 26, 2013 Mine has lost it's mojo. Feels odd (sort of rough/binding) and now only illuminates instrument lights at full turn. No dimming function at all. All exterior lights function fine in all modes. Sometimes the instrument lights will not come on and I have to re-twist the knob several times to get them on. Anybody know the drill on fixing. Buy new? Rebuild? Sources? Also, it looks like it comes off the harness at the back of the switch...is that right? Any advice would be awesome.

Guest 63 rivenge Posted September 27, 2013 Share Posted September 27, 2013 I had the same problem....BUT.....pull the harness off the switch first.....at the base of the switch is a button, push that in, and pull the knob out out first, buy a new one, and install Link to comment Share on other sites More sharing options...
1965rivgs Posted September 27, 2013 Share Posted September 27, 2013 Sometimes the coil of wire which acts as a reostat to dim the dash lights develops corrosion from lack of use. Try cycling the knob 20 or 30 times to clean off any corrosion build up. Other times the coil is burned and this technique is not a solution. Worth a try, Tom Mooney Link to comment Share on other sites More sharing options...

petelempert Posted September 28, 2013 Author Share Posted September 28, 2013 Unreal. It worked. I just came back from about 20 twists on the knob. Suddenly, the dimmer worked. Unbelievable. Thanks. You guys are the best. PRL Link to comment Share on other sites More sharing options...
