hi i have 97 mondeo 2.0 zetec (silver top) its only done 37k miles and has spent most of its life doing short trips or parked in garage. I have a problem with temp gauge not working, although somtimes it does move a tiny bit, car drives perfectly heaters warm and dosnt over heat, just wondering if anyone has any ideas as to what the problem is. Any help would be much appreciated cheers.
