I've got a 91 4x4 saff. and a few weeks ago when you turn the ignition on the systems check with the picture of the car (tells you when doors are open and lights are out etc.....)and the fuel low warning light and low water level lights,have decided not to work until about 20mins into the journey.I've swapped the actual displays with another cossie and they all work fine on the other car,i've wiggled and checked wiring with no luck anyone any ideas?Is there a control box anywhere that controls this system?
