Has a burnt out bulb ,have to take instrument cluster out an replace bulb . Here is a video , first part he shows how to replace stepper motors ,go to 9 minuets 33 seconds that's where he starts on the light bulbs ! How to Fix GM Speedometer Instrument Lighting
First remove the bezel around your instrument panel.From there locate the 7mm hex shape screws that secure the panel to the dash. Unplug all the connectors on the back of the cluster and remove the unit from the vehicle. You will see several black and a few grey buttons. They look like micro miniture gas caps. Turn them counter clockwise to remove them. You will see mini bulbs attached to them. basically these are the sockets for your instrument panel guages. Replace burnt out bulbs as needed.
There are several bulbs in the dash that come on with the headlight switch so it is unlikely that they all burnt out at the same time.I would check the instrument light dimmer switch for power in and out of it before blameing dash bulbs.You should check the plug to the light switch to check for power out of it and to look for burnt wire ends.
you do not need to remove the dash, just the instrument cluster, to do this, remove the bolt in the hood latch, then the bolt on the other side of the steering column cover panel, then the panel will pop out, this will uncover two screws on the instrument cluster finish panel, remove these two screws, and the three pointing upwards in front of your gauge cluster, this panel will then come out, disconnect battery, remove the four screws and the instrument panel will come out, unlpug it, check to see which bulb is the service light, and replace!
You can remove panel screws, remove and pull back dash panel, then you will find a couple more screws that holds on instrument panel Remove these screws, pull back panel and you can see the bulbs. They turn and pull out.
It seems that the bulbs went out or the ribbon cable that runs behind the instrument panel burned out check on a junkyard for a replacement instrument panel and replace it, verify that the truck you pull out the instrument cluster is the same year and the same model.
hi.... Its not a quick job. You need to remove the instrument panel. Once removed
the bulbs simple twice a quarter turn and you can replace them. removing
the instrument panel varies on different cars, often you can do it
without removing the steering wheel.
You would normally take off the plastic under the steering wheel. lower
the steering wheel as far as it will go. there should then be screws
holding in the plastic around the instrument panel.
There is a plastic garnish surrounding the instrument cluster held in by 2 philips head screws. remove the screws and gently pry the garnish from top first then sides then it should pull out.
Then remove the 3 screws holding the cluster in place (2 bottom 1 top). Once that is done gently flip the cluster bottom up and pull out some to expose the wiring harness. Remove the 3 connectors from the back and then the cluster will pull out.
There are 3 bulbs that control the overall lighting of the cluster. They are spaced about every third across the rear of the cluster. They are the larger Green knobs. Remove the 3 large green knobs and replace the bulbs with the appropriate size. You can call your local parts store to find out the size.
Its a 5 minute job and does not require the entire removal of the dash board.
