When you open the Stack backplate, there is a small sachet with material which should prevent any moisture inside. You can take this out and dry the stuff in an oven on very low setting. (1-2h on 50-60*C should do it)
Maybe it helps.
Thanks, is that the plate that is below the clocks held on with 4 screws? As well as drying out the material as you suggested maybe a sachet or two or silica would help as well?
sorry to go on but reading other posts i am trying to piece things together.......
...also the LED does not work on the console and the hazard work but most of the time no indicator lights come on, also have a bulb on the dash out ( (i think)
