The instrument and dash lights on my 95 850 Turbo Wagon have gone from operating intermitently to flickering to completely out. The fuse is good. On the rare occassion that the lights come on, the intensity slider and headlight switches seemed to work fine. One symptom is that when the ignition key is first turned on, the lights would come on for about 1 or 2 seconds, then go out before I rotated the ignition switch further to the start position. Is there a relay, switch, power connection or ground failure that has been found to be a common cause for this?
