Hi

I notice on cold days my speedo and rev counter steams up or mists up, assume its damp getting in and maybe needs new gaskets etc.  Is this a send-away job or can an semi-skilled like me attempt to do?

Hi Richard,

I feel that a gasket will not stop moisture getting as there are too many little gaps/holes. The problem is the cold glass on the gauge compared to the temperature of the moisture.

When the car is driven the 'fogging' will soon go.

The dew point of the air in the gauge cases is higher than the glass exposed to cold outside air. Do you drive your car outside from a warm garage ?

Hi Mike, no, its a garage I rent about a few Km from my apartment so not heated at all, but I did see this occur when driving and it was a chilly day or chilly evening.  When I looked at my dials on my car yesterday in the garage, I could see the speedo especially was quite steamed up.   Heated garage . . oh what a luxurious thought!

Water's getting into the gauge from rain or washing. If you  have the skills to  remove the gauge you would be able to replace the gaskets behind the glass. I purchased new gaskets from a UK Smiths/Jaeger specialist and followed instructions that were readily available on line. Unfortunately the link to the gauge repair instructions is in my home computer which I can't access at the moment.

Hi Mike

This is not a today job, but a one day job so if you find the manual one time I'd much appreciate it,

No matter how much you seal the front of the gauge against water ingress - a good idea if they leak, all the gauges have a light  bulb or work with a heating element such as fuel and temperature. When the gauges are working or illuminated they heat up and the slightly pressurised air  in the gauge escapes, then as the gauge cools in the garage air is drawn into the gauge along with some moisture.  Eventually after a large number of heating/cooling cycles the moisture accumulates and  gauge will mist, it may be that fitting LED's which run cooler would reduce the volume of air cycled, but then with less heat when they do mist it will take longer to clear. Running with sidelights on and the gauges rheostat turned up to full brightness (and maximum heat) for a short while on each trip will speed the clearance.

I'm not sure that the problem is permanently curable.
