How can i fix the Dash light?
First you have locate the knob or the dial controls. This is what brightens the lights on your dashboard. Then you need to check the fuse that controls the dashboard lights. Most of the time the fuse needs a simple replacement.
No the dash lights should be with your parking lights. comment2: They are on separate circuits. Power usually goes from the "taillight fuse" to a small 5 amp dash light fuse and then to the dash dimmer wheel or knob. Then it feeds the dash lights. A blown tail light fuse makes the dash lights go out also. A blown dash fuse only affects the dash lights.
Is there a circuit breaker that controls the tail lightsheadlights and the backlights in the dash of a 1999 olds silhouette?
If the needle is out you have to replace the needle itself as its an LED light. If its a dashboard light then you have to remove the face plate(two screws on the top of it) and take out the instrument cluster, take it apart and replace the bulb. Although the needles are engineered to be removed/replaced, you cannot buy a single needle. You must by the entire instrument cluster to fix this.
