Astra J 2012 1.6 petrol
Well a bit more than misting but certainly water related...
No wet carpets nor water in boot.
On a wet day or driving in a cool evening, we stop for fuel, say. When we start off again as soon as we do fast left turn (onto a motorway or roundabout), all hell breaks loose on the instrument cluster.
Chimes and every warning under the sun comes on in succession. It you leave it to its own devices, it will also switch the radio on/off, stop showing turn indicators, show/not show 0 rpm and mph, and occasionally shows you're on full beam. Meanwhile, the car drives totally normally. This can go on for miles.
But we found a solution - turn on the front demister. That cures the problem in about 20 seconds and it stays cured for a long time.
We usually drive with the aircon on low, but not exclusively directed at the screen. This never happens if the car has stood overnight before you make that stop after a couple of hours.
So one of the models I have in my head is that there is water coming from a/c heat exchanger that is pooling when the car is stopped and turned off. It slops to the right hand side of the car on that first left-hander and either dampens a control unit or gets into cabling. A blast of aircon drives it out really really quickly. But I have no idea where to look for this sort of problem.
I've replaced the pollen filter and thought that made a difference for a while.
It's controllable but can't be doing the instrument cluster/controller much good, so I'd like to nail this nasty little devil. Any pointers please?
