    Almost every time I start up, the three dials for heating and air con start flashing and clicking.

    Wherever I left the dial positions is where they stay. no turn clockwise or anti clockwise will move the red light on any dial.

    Sometimes after about ten miles run, the unit will suddenly start to work properly.

    Am I in for a new printed circ board or what?

    Can any one please offer constructive comment.

    Regards

    Calvados

    The first thing that I would do is to give the unit some hard taps, either do it when not working or working, it sounds like a dry joint or connection fault,,we have not had this one up before
