Gauges are fogging....help

[FireChick]

Don't know if it's just because of all this rain (3 fricken weeks straight of it!!!!!!!) BUT... ... .



My boost and EGT gauges are severely fogging up (mostly the EGT which is on the bottom).



These gauges are on the A-post. Have had them on for approx 1 1/2 yrs but this is the first time this is happening.



So bad that I can barely see the numbers on the EGT gauge at certain times:{



HELP! ANYONE!!

FireChick- do a search for fogging gauges. Devildog started the post you want to see on 12/13/01.

Autometer?

I had bad foggining problems with my Autometer gauges. I finally took them out and exchanged them under Warranty. Kind of a pain to send them back but it was worth it. The new ones have never fogged, even in the rain.

Nik... . It's the combination of you using your A/C and the humidity that enters the cab when you open the door in this wretched foul thick airmass we call connecticut atmosphere. the guage glass stays cold along with the INSIDE of the gauges. Everytime you open your door you let more moist air into the cab that condenses on the inside of the gauge faces. It's mainly due to the guages open design. Yes there is a fix for it by replacing them but IMHO I just turn on my cab lights and the bulb heat defogs 'em

The Wifey's hair dryer will do the same.



ps my isspros have never fogged.

Hey Fire Chick,



My AutoMeter Trans. Temp. gauge fogs up too, its on top. The other two, boost and egt's don't. I agree with the Tool Man. I have had my a/c on all the time this past couple of weeks, because of the humidity. I think its a bigger pain in the arse to change out for another, I'll live with it for now.

So what's so bad about Sundae's ?



Thanx guys... . tried all of the above (with the exception so far of withdrawal and reinstall ).



It's a pain in the butt, but you guys are right... . thanx

A little bit of normal moisture in the air gets into the gauges. Then the light bulb evaporates the moisture and it fogs up and condenses on the inside of the glass. Since the gauge is seal relatively well, the moisture can't get out. So it just repeats itself depending on the barometer and temperature.



You could take a very small carburetor jet drill and drill a hole in the back of the gauge somewhere - be careful not to hit anything important - so the moisture can come out when the bulb heats the air.
