Question
-
- I get a build up of condensation on the inside of the faces of the fuel and temperature guages when I run my car. How can I prevent this?
Background
-
- It's the bi metal strip gauges that mist up. There is a small amount of heat given off which, with the relative humidity in the instrument and the cold glass surface, causes the condensation.
Answer
-
- Remove the instrument concerned. I started with my worst offender; the water temp gauge. Carefully mark in pecil on the underside of the plastic cylinder/housing a couple of parallel lines about 3 mm apart and approx 1/3 of the circumference. Then, using a junior hacksaw C-A-R E-F-U-L-L-Y cut along those lines taking care to blow away the swarf before you cut through the 'can'. Obviously, you don't want to cut too deeply but it isn't that bad a job. The vitals don't lay tight against the sides of the can. I then used a Stanley knife to join the slots and remove the section. Don't be tempted to drill holes as this'll create more swarf and you could (will!) drill one hole too deep and hit the vital internals. Now with care and tipping it to & fro you can ensure no plastic swarf gets back inside.

- Next, refit it and refasten all the plugs/wires/connectors. Yes, it's open to the air................ but that's it. Misting up problem stops!

- For those not wanting to attempt this fettling action, the answer is indeed to drive with the side lights on, and it helps if you up the wattage on the instrument bulbs then all you darling instruments have little anti-condensation heaters.
