Instrument cluster

[Stig9]

One of the instruments on my 3.2 Carrera dashboard seems to have a leak where moisture is forming behind the glass.
It works as it should but does not look good.
Does anyone have experience in how to remove the instrument from the dashboard and take the glass off so that it can be cleaned up, or this a specialist job?

It will just do it again, its the law of physics Jim!

I went for my 3.2 MOT yesterday and had the heater on for the 30 minute drive. After the test the speedo had a lot of condensation on the back of the glass, I hadn't seen this before. On the return journey I turned off the heating and within 5 minutes the condensation was gone.
My guess is that the heat in the cabin compared to the cold dash and luggage compartment behind the clocks caused the effect.
Charles Marsland always suggests pushing the dash clocks out from the luggage compartment rather than pulling them out from the cabin. Removing the glass sounds much more of a specialist job. Steve

Try putting the dial in the airing cupboard. The problem is the cold damp air in the front boot meets warm air in cabin. Try leaving the front boot open as they can be very damp. if you do remove boot light fuse. Close the boot before driving off.

Close the boot before driving off.

Very common to get fogging of the petrol/oil gauge..it’s one of the many quirks of the car.

I recently removed the Speedo from my 3.2 carrera. The instrument was easily removed from the front where access is good. I used trim tools purchased on line as below. This is easily within normal DIY skills, but glass removal is a different matter as with the speedo, the bezel is crimped to the instrument casing. I did remove the bezel but it was a real challenge. Hope this helps

I've not removed any clocks myself, so have no experience, but do have a little with misting up of external cameras and housings (similar).

I'm sure it's because you previously have warm/moist air inside the clock - or it gets introduced into the clock each time (heater/ warm air?). When things warm up the air inside is then high humidity and laden with moisture, which will then condense on any surface that is colder, such as the glass, and especially in my case as a Targa and I've always got the roof off.

Rather than try to "open up" the clock, maybe first try to expel the moist air then seal it up. I assume the light bulb holder when removed part "opens" the clock? Maybe then heat it up with hair dryer to get moisture into air in an attempt to expel it, then seal clock up with light bulb holder.

With camera housings, we do this and place one of those desiccated sachets inside to absorb and draw/hold the moisture. Your trying to do similar. Might avoid the need to dismantle the clock.
