I have a fiat stilo abarth and when it rains the instrument panel goes out, when the sun comes out it seems to work, i did have problems with the drainage in the roof, but got that cleared, also the passenger rear light cluster played up, one of the wires had burnt out, but got that sorted, does anyone have any clue as to what it is, everything else in the car works fine, even when it all comes back on its still clocked the miles i have done!

Hi there

I had a similar problem in that my instrument cluster (I assume that is what you mean by dash) would often not work in damp conditions. It was faulty and needed to be sent away to be fixed - sent it to cartronix who returned it within 36 hours - it now works absolutely fine. Search for instrument cluster removal on this forum to see how to get it out, it's very straight forward

i can repair your instrument cluster too for a competative price (info by PM) - even sending it to the Netherlands it could still be cheaper ...
In most cases the cluster will be sent back on the day of arrival.
I do lots of these clusters, even did some repairs for Norwegian customers...
