Question about 1999 Chevrolet Suburban
Can anyone tell me how to replace the instrument lamps on a 1999 suburban? The lamps I need to replace are the ones in the radio and behind the AC/ Heater controls. If the radio must be pulled can you tell me how to pull the radio?
often the lighter and dash lights are on the same circuit, if the power port doesn't work then you got some fuses out most likely as jigsawbill has mentioned.

I'll tell you, but when you go to do it, you'll probably curse Chevrolet, your car, and me! lol!
You have to reach behind the dash. Even with the seat in the back position, you'll turn into a contortionist! Place an old couch cushion, or something similar on the ground/driveway next to the car, with the door open. Kneel on the couch cushion. Reach up under the dash, and back behind it, with your left hand, while holding onto the steering column with your right.
It's hard to describe this to someone who has never done this before. (Just think. You'll be the expert, when someone you know asks you, when you're done!)
You are feeling for a plastic bulb holder. This holder is about the size of a dime. It resembles one of a gas stove's knobs. It has a round base, and from the middle of the base, it comes up into rectangular shape. If you look at this -> T <- the base is the top of the T. Turn the T upside down, and you'll have the basic shape.
This plastic holder has the lamp bulb in it. You turn it to the RIGHT.
As you face the instrument cluster, it is turned to the Right. You just turn it one quarter turn, then it will come out.
Once you get one in your hand, you'll know why it was difficult to describe. You'll also immediately see how it turns in, and locks into place.
The bulb itself it extracted, by holding the bulb holder in your hand, bulb facing you. You push in, and turn the bulb to the Left.
It is at this point, that I advise you to wear some protective gloves of some kind. The bulb base, could be corroded down in the socket. You may exert enough force to break the bulb, and cut your fingers.
I advise Safety above ALL ELSE!
I also advise that you replace one bulb at a time.
Notice the brass metal ring around the bulb holder base?
This corrodes after time, giving a poor contact. You can take a little fine steel wool, and clean it up. Use care as the steel wool can catch, and bend the brass ring, misshaping it.
Behind the dash panel that you can't see, is a thin plastic flat strip.
Another thing hard to describe. Envision a large U shaped flat piece of plastic, on the back of your instrument housing. The U shape will be upside down, in relation to how it sits on the back of the instrument housing. It's about 1/32nd of an inch thick, and about 2 inches wide.
There are thin flat strips of copper, making a path all the way around this strip. There are holes in this strip, for the various lamp bulbs. The flat copper strips go around these holes, making a connection to the bulb holder. That's what that brass ring on the bulb holder contacts, when it's screwed in.

It is behind your glove box. You have to make sure when take out the glove box be careful of the tabs and also remove the wire on the side. You will see a black box with a a bunch of wires coming out of it. You need to disconnect that mess of wires and remove the two screws that are holding the resistor in the box. Remove it and put the new one in. Be care not to bend the coils all up on the resister. Hope this makes sense, keep me posted, be glad to help.

Your public library will have a manual covering your mechanical repair. Moreover, they have the automotive shops online software called AllData. It is the best auto technician database available today. You can print out specific troubleshooting procedures, diagrams, step-by-step istructions, and soforth. The typical person cannot afford to pay for this service, just automotive dealerships, etc... that is why the public library made it available to everyone and for free to view and print out material. This should Fixya! Good Luck!
