Answer

Hello and Welcome to justanswer...

There have been many cases of poor connections, the electrical block connectors going into the rear of the dash being loose and causing exactly as you describe...

When the problem next happens - give the top of the dash a sharp tap with the palm of your hand - and usually that will correct the fault - also confirm the fault..

It has to be said though that while that will show th e fault up its not 100% so what Im saying is, if that doesn't affect it - it still is likely to be the issue and should be checked out..

Vauxhall tend to tighten or replace them depending on the extent of the problem so you may wish to have a word with them about it - or of course tackle it your self..

I Sincerely hope I have helped you - Please ask me if you need more help...

Kind Rgds, MIKE
