I have a 1991 Chevy surburan and it has no tail lights and no dash lights, all fuses are good
I think the #1 brake pressure switch is faulty. Located under dash, top left of switch manifold. Tight spot, need deep 1 1/16 or 27mm deep thin wall socket.
Under the dash board panel on the passenger side.
yes there is a small toggle switch under dash to turn them on,
check the fuse for dash lights
Most dash lights have a setting knob to turn the dash lights on and off and to dim them, maybe this switch is off.
Very carefully!
If all the dash lights are out then there is two causes for this. The first is all the fuses have blown the other is the relay for the dashboard lights has went out.
water in the wiring or a low battery
Check your fuses
some of the lighted buttons on the front dash are on longer lite when lights are on, how do i replace them on my 2000 Cadillac deville dhs.
You left some wires unplugged.
