Instrument cluster foggy

[zalle]

Hi guys,

Any ideas for fixing this? Obviously it's on the inside...

When it is heated with a hair dryer does it clear up?

Need to try that, I'm away for 2 weeks. My initial idea was to remove it, cut the cup around, clear the glass from the inside, and glue the cup back with silicone.

Is that the only foggy instrument?  The hair dryer should work, but be aware it could take a while to "cook" all the water vapor out of the housing.  I would pull the gauge out of the bike and put it into a warm(NOT HOT) oven set for 60C.  Pull the gauge light which will put a large opening in the back of the gauge.  Could take as long as a couple hours in there to get all the water out.

Don't cut the case.  That will just make matters worse.

The other one is too, the temp. gauge. Clocks are fine...

The hair dryer was to determine if it was actually condensation and not a defect on the interior of the window. Your strategy will determine what the problem is, Zalle.

Ok, I'll try that when I get back.

There's a lot of stuff I'm doing to it. I'm going to remove the fairing, gas tank, etc, and check everything.

Should I post photos of the process somewhere?

Yes. Start a thread in the Projects section and post them in it as you work on the bike.

I tried a few of the fixes posted in these forums for my fogged up instrument cluster. The only thing that worked was silica gel. I don't think you can get away from the fact that there air has moisture in it which condenses on the cold glass in certain weathers. It's very hard to seal the instruments completely.

Yes, the temperature and fuel gauges are not air tight due to the light bulb socket that plugs into the back of the gauge.  Moisture gets in via damp air and is hard to get it out as quickly as it got in.  This is one  reason why it is not a good idea to replace the gauge light bulbs with LED's.  The bulbs act like small heaters to help clear moisture from the inside.

It is also possible that the plastic lens has been clouded by a previous owner cleaning it with window cleaner containing ammonia.  If that is the case, there is nothing I know of that you can do.
