These are Sun-Mullins (sp?) that were popular with CC in the 90's. Unfortunately there are a couple of issues. (1) they are prone to failure, and (2) they are expensive.

The good news is that in many cases the switches can be cleaned. Turn off your electrical completely (shut down the 12V internally), and you can pop the tops of the switches. Then spray some electrical contact cleaner in them, and let them set for around 30 minutes to dry.


This fixed issues with my cruise control, which were all caused by dirty switches. I'm not 100% sure, but I'm guessing that the ones on the drivers left side (which face upwards), are more prone to collect dirt than the vertically mounted switches.

Nick Hessler can certainly tell you more, but he indicated to me that sometimes when they glow red, that is an indication of a switch failure. He told me (I think I've got this correct), that in normal operation most of the switches are to glow green or orange, and that red generally indicated a problem. This may not always be true!

Anyway, contact clean can work wonders on these little puppies.
