I can barely read the speedometer on the digital dash of my 92 Crown Vic
during daylight. The other numerals (temp, fuel, trip milage) are all
bright enough to read. I've turned the headlight know counter clockwise
to make it bright a possible, but still too dim. Is there a way to clean
behind it or some other way to get it to brighten up?
Thanks

If it's the backlighted LCD type, there's another bulb WAY in the back of the
cluster just for day lighting. If it's the neon tube type, there are separate
power sources for the day & night illuminations; the night is triggered by the
external lighting circuit, and the day is triggered by the ignition.

there is also a relay module under tha dash that supplies this circuit i had
the same problem with my t-bird. if the module is bad insufficent current
pass through the deadlight circuit to illuminate the guages during the day.
the module cost me about $40.00 at NAPA it was located under tha dash next
to the radio. there should be a cluster of about 6 of these there each
controls power to a different function
