Cheers Dave. I think that the switch is ok as the in/ out movement is fine, it's only the up and down wheel adjustment that seems a problem.
I took it to a dealer today for some work, the mechanic moved my seat and steering wheel as part of that visit, but when I tried to put my positions back to suit me then I discovered the problem. - I just thought that I may be missing something obvious in the use if the switch. Looks like I might have to go back and let them take look. Thanks again
Thanks Tim, I just went out and tried your good suggestion, but sadly no joy. Looks like the issue is with the vertical motor. - off to the dealer again by the look of it !
I wish that I didn't love this car so much, I'd have ditched anything else by now after so many issues, but the Mas is going nowhere no - way !
