My dashboard light isn't working but my turn signal light, emergency break light and all other warning lights work, just not the backlight so I can see the speed i am travelling in the dark.
The lights in your Instrument Panel are not working at all? Or, do you have SOME lights on, such as the one in the heater control panel, or behind the gas/heater guages?
All of the interior Instrument Panel (dash) lights are on the same circuit (switch) so if some of them are on, you have to replace some bulbs in the Instrument Cluster. If ALL of them are out, you need to replace the Light Switch. (Unless, of course, ALL the bulbs are burnt out!) You could test the switch with a volt meter, to determine whether it is the switch, or just the bulbs.
You will have to take apart your dashboard to some extent in either case. If it is the switch, only remove as much as neccessary to obtain access to the switch. If you are going to replace the bulbs, then it is more involved. You will need the proper Driver(s) A philips head, or a torx, whichever it is. Maybe even a 1/4 inch socket set. (Metric) There are a variety of screws and bolts that hold the Instrument Cluster in place. On some models, it is neccessary to 'drop' the steering column. There are two bolts that hold the column up to the dashboard, and once you remove these, the column just kind of sags down some. One thing you must be careful of is the Speedometer Cable. This is connected directly to rear of the cluster. There is a push bar on it, that you depress, then the cable will slide off. There are also a couple of wire plugs that are attatched to the back, so you won't be able to pull the cluster out more than a few inches till you unplug these things.
Once you have the cluster off, the little black round bulb sockets just turn a quarter turn, and pull out of the circuit board. They use a small bulb with no base, it is just glass, with two wire ends sticking out, like Christmas bulbs. Just pull the old one out of the base, and push a new one back in, then replace the base into the cluster.
When putting the cluster back in, be sure that the speedometer cable is pushed back on all the way, or your speedo won't work.
