Technical Flashing lights and no speedo or fuel gauge

[ErnieBeccs]

For the last few months my V reg Multipla has periodically after rain:

1) Flashing air bag light.
2) Speedo not working.
3) Fuel gauge not working.
4) Clock and mileometer not working.

The problem is getting worse and the above are staying not working for progressively longer periods, ie days, then suddenly then will start up again.

I have taken out the dashboard and checked for loose connections, replaced the speedo unit, the original problem started after a rainstorm when the sunroof leaked.

Can anyone help please.:bang:

Check the fuse? If its blown but damp it could explain it... Current could flow through the damp surroundings, despite the fuse being blown, or it could probably ark... Check it - it can't hurt...

I thought I wud revive this thread, no-one seems to have an answer yet.
We had torrential rain not long ago, the car started ok but my wife said she didnt know what speed she was doing, so checked it and the next day it was warmer and was working again.
It must have been extreme weather co its not done it since in spite of lots of rain wind etc.
Perhaps a fiat agent might know? not a chance.
I wud just like to know where to spray a damp prevent like wd40 etc.
Thanks Barry
