Console gauges get foggy in humidity, especially cool humidity. Any solution other than sending to CA? Original glass lenses. Don’t have bezel tool. (IMG:style_emoticons/default/sad.gif)

I've been told condensation is a symptom of residue on the inside of the glass.
Reach out to Bill. I bet he can make your gauges sparkle and refresh your needles. Trust me. Quality work at a fraction of the insane big shop prices. |

Gauges are not sealed. A gauge rebuild isn’t going to prevent future condensation when temperatures and relative humidity encourage it.
Smoking was very common in the 70s and leaves behind a smoke film. Likewise repeated condensation and off-gassing from vinyl and plastics will leave a film. I have seen gauges with extreme cloudy film inside the glass that can only be cleaned by disassembling the gauge. Your pictures seem to look more like this to me than simple condensation. |

When not humid a bit of haze on the inside of the temp gauge that could use cleaning anyway. Really showed up this morning. Garage kept, of course! |

I cleaned my own. The crud on the inside of the glass was obvious, and worse with even a bit of condensation. It was too obvious to live with after I had the speedo apart (and cleaned that) and added a new oil pressure gauge to the console.
The ghetto method of removing and reinstalling the bezels is crude, but not visible from the front. |

I believe @bkrantz is referring to the method of putting the gauge face down on a towel or soft surface and using a small flat blade screwdriver to work your way around the back of the bezel, twisting the blade to uncrimp it.
Go slow until you get the feel - try a couple of different blades. Eventually, you'll be able to work the bezel off, remove the glass and give it a good clean. I use compressed air and wear rubber gloves when handling the glass. Pop the cleaned glass back in the bezel and work it back onto the face of the gauge. Place it face down on a cushioned surface and work your way around, putting the crimp back on. I like a fairly wide flat blade for this but you'll see what works. |

Thanks! Will give it a try - slowly and carefully.

That's John Bell (not Bill), as I recall. He did a combo gauge for me. He and his son do amazing gauge work for very reasonable prices. Super easy to work with. |

Here's a photo from when I did my tach. I tried to be patient and slow, and VERY gradually pry up the edge of the retaining ring. After cleaning the glass, I crimped the edge back the same way.
