My 2001 f150 is not illuminating from the dash correctly. The odometer isn't visible and whenever headlights are on it doesn't illuminate to full brightness. I can barely see it switch on and the odometer itself then starts to light up very dimly. So dim that I can barely see anything and can't make out the mileage itself. I checked the dash light fuse and it's fine. I'm a bit lost on what could have caused this. Thanks for the help!
