Condensation in Temp and Fuel gauges

[jvespey]

After just over a year off the road for a "simple" project that grew and grew in scope, RQB-4245 is back on the road as of this past weekend.

Now that it is back up and driving, I noticed the temp and fuel gauges seem to get some condensation on the inside of the glass faces after the car has been running a bit. I do recall that it did this before, also, so it's not apparently related to anything I did over the past twelve months.

The temp gauge, on the left side of the instrument cluster, fogs first and then the fuel gauge, on the right. Speedo and tach do not fog at all.

My first thought was perhaps a leaking heater core, but I'm wondering if anyone else has experienced this before and gotten a resolution?

My gauges do that same fog thing. After a bit of run time they clear. I think it is just Houston humidity and wide temperature swings...take a little time to equalize.

I get the moisture, too during certain times of the year.

I turn the instrument lights on to heat up the glass and voila! Fog is gone.

I've seen my '83 Avanti's gauges fog up occasionally also....Just part of the 'Avanti Experience' I guess!

Same thing happens to me too. Not sure how exactly it happens but it goes away.
