Backlight
I have a 2004 F150 FX4. When the lights are on, the small LCD display, containing the odometer, in the lower right corner of the gauge cluster is not backlit. It was suggested to me that this was due to a small light bulb being burnt out. I disassembled my dash, unable to locate the light bulb. It appeared as though if there is a burnt out bulb, I would have to remove the circuit board on the back of the gauge cluster. Can anyone confirm or deny the light bulb theory?

Yes, likely a bulb, they are those lil gray and black plugs on the circuit board. Helpful Post: https://www.ford-trucks.com/forums/6...ml#post5286310

HALOGEN BULBS FRIED EVERYTHING!!
A friend of mine had 1 burnt out headlight on his 20 year old MERCEDES and he bought some blue headlamp bulbs of unknown or un-noticed wattage at an automotive surplus wholesaler. I was with him & I almost bought a set for my truck that day, BUT SKIPPED IT.
So it was a cold day and he just replaced the 1 burnt out one.
A f4ew weeks later he has 2-fried headlamp wiring assemblies, 2-fried sockets and both the old and new bulbs melted the holes where the bulbs screw into the lamp assembly. WHEW.
Whata mess on a nice old car!
Just wondering how changing 1 bulb to higher wattage can fry both harnesses, and make the original bulb burn hot enough to melt a hole in the opposite light????
