I have a 2002 chev tahoe... the dash board lights for the instrument panel won't turn on at night when the head lights are on... (can't see my driving speed) the panel lights work fine when i turn them on manually with the control switch but these cause all the interior lights to turn on ... HELP

SOURCE: 1999 tahoe

aftermarket radio ? dimmer cicuit in radio harness for dash lights fuse illumination good?

SOURCE: tail lights and instrument panel lights dont work

The Dash and Tail lights connect to the same fuse in most cars. if the fuse is okay, check to make sure the tail lights and/or dash lights are properly grounded. all bulbs could be blown...but highly unlikely.

Maybe a relay but maybe and more probably a broken wire Get a diagram Chilton or Haynes manual

under the dash on the right side ,look for a plug with 5 wires . That switch is called a RHEOSTAT.(fan speed control).Sounds like it is defective
