oil pressure gauge fogging up INSIDE car? help?

[91stang50GT]

This might sound werid but, i just put autometer mechanical oil pressure and water temp gauges in a guage cage inside my car about a month ago. Today while driving to work (in the light rain) i noticed that my oil pressure gauge glass was foggying up on the inside as an older headlight would do. After i shut the car off, it cleared up after a few minutes. When i left work, it did it again. Is there some kind of seal that could be messed up? the gauges are only a month old!

I was told by an auto meter rep that there gauges are not water proof. I was asking because i wanted to get a cowl that had gauge pods in it and was worried about the rain. that being said he said some people put a beed of silicon on the "joint" to help seal them. If your gauge has always been in your car i don't know how it has gotten moister in it but perhaps it is condensasion. Maybe just run a hair dryer over it for a while to get all the moisture out of it.

yeah i just dont get it, the gauge has never been outside the car and it just started doing it today and only while the car is running. I've seen quite a few people with gauges on the cowl such as FP without any problems.

My AM water temp gauge does that too when its humid out.

My Vac and FP gauges fog up too. Only in the rain/heavy humidity. Driving with the AC or heat cranked up always clears them up eventually. Regardless, I was pissed, so I called Autometer. They WILL do something about it for free, you just need to ship them. He told me they open them up and put some kind of de-moisturizer in and then seal them. I just didn't want to be without them so I never sent them out, but since I haven't driven that car in over a month and never will again I guess now's the time...

Use a hair dryer to heat the gauges up a bit, the heat will dry the gauges out. Then you can smear a little bit of clear silicone bathtub sealer on the back around the joints between the case and fittings.

Just don't let your wife or G/F catch you with her hair dryer - women get possessive sometimes...:

Autometer will fix this if you send the gauge back. They can apply 'anti-fog' stuff to them. I emailed them a while back about fixing this problem on my FP gauge.
