I just got a 91 Thunderbird with the 5.0 engine in it, and that instrument panel is dim and barely see able. I have tried messing withe swicth to turn up the lighting and not working. Was wondering if someone has a wring diagram for the instrument panel or even if this has happened to anybody else and if they were able to fix it that info would be much appreciated. Thanks for the help

 

most probably the dimmer switch they go bad with time, to be sure remove the dash panel around the switch and and jump off the contacts, should light them suckers up some bright

 

i have a dimmer switch if you need one..i also have an instrument cluster if you want
