Take out the screws holding the instrument panel in, pull it gently away from the dash being careful not to unplug or pull out any wires. there should be a plastic retainer that you and pull off to get at the bulbs.replace the blown bulbs and reinstall the panel..

You can buy the Mass air flow sensor separately.

There are two screws under the lip that hangs over the steering wheel and instrument cluster. Remove those two screws and pull the top section toward you and down. This will remove the whole instrument cluster. Then remove the connectors to the harness. You will see little circles with x's on them and should also notice two small pieces of copper. Those are the bulbs. it should be obvious which ones are used for the speedo. You will probably need to get the bulbs from a dealer for around $10. To remove the bulbs use a phillips screw driver twist it about a half turn and the bulb should come out.

you have to take out the instrument cluster and then twist the hold down a half turn and pull to remove bulb and hold down from cluster then remove bulb from hold down replace with working bulb and reverse to install working bulb then reinstall instrument cluster.

I have never seen one you couldn't change. You will probably have to take the instrument cluster and the radio out. Little bulbs plug in the back of the inst cluster. The radio might have a bulb down through the top or you might have to take the face off the radio to find it. I have changed both before.

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.

Probably too late but I had the same problem yesterday. Try changing your battery. It sounds crazy but it worked for me.

The bulb is probably loose and/or burnt out. If you are mechanically inclined you can tackle this job... This procedure is the one i use, most often it's the blue high beam indicator bulb that goes so if you want to change it while your in there.....(hint hint)
Disconnect and isolate the battery negative cable. Wait a good 2 minutes to allow for air bag deactivation...NOTE: USE CAUTION ...Lower the tilt wheel to lowest position.
Remove the cluster bezel from the instrument panel.
Remove the two screws that secure the upper mounting tabs of the instrument cluster to the underside of the instrument cluster hood formation of the instrument panel top pad.
Remove the two screws that secure the lower mounting tabs of the instrument cluster to the instrument panel structural duct.
Pull the upper mounting tabs of the instrument cluster downward, then pull the instrument cluster rearward far enough to access the instrument panel wire harness connector for the instrument cluster. Disconnect the instrument panel wire harness connector for the instrument cluster from the connector receptacle on the back of the instrument cluster housing.
Remove the instrument cluster from the instrument panel. Now do you remember which bulb it was? You can now see where the check engine light bulb is mounted. Twist and remove, install in reverse order. In some cases they are just loose or not making good ground, but after going through this just to access that lil bugger, i'd replace it.
I hope i have helped you and if you feel i have please acknowledge.
Be well and keep the cherokees alive....

there is light bulbs behind the instument cluster. You will have to remove the screws, than pry off your panel and change the bulb.
