If you're CERTAIN that the fuse is good, check the headlight switch. There is a separate circuit inside the switch that controls both the dashlights and tail lights. If the INPUT to that circuit is working but there is no power out from the switch, you'll have exactly the problem you duscuss.
A blown fuse can cause the dashlights and taillights to stop working on a 2001 Dodge 1500.
Start with checking the fuses.
The bulbs should be checked on a 1993 Dodge Dakota if the taillights are not working. The plugs on the trailer package should also be checked to make sure that they are working.
Check the switch.
Bulbs blown?
On most vehivles the live feed for the taillights brances from a connection in the back of the trunk. It is probably a poor connection or damp in this junction. If the whole cluster isn's working it is probably a poor earth.
The fuse has burnt out.
Check fuses
Either blown bulbs or blown fuse check for blown fuse first under hood in fuse box labled taillights
check ground wire on rear of frame for Chevy trucks
Your dashboard lights suddenly not working is almost always your indication that your taillights are out. If the fuse for your taillights is blown and you replace it, your dash lights should be fine.
Find out why it is not working. Do you have 12 volts at the bulb socket. If not, then you have a loose or corroded connection. If you have 12 volts then the bulb is blown or not making good contact. The license plate bulb is wired into the taillight circuit and operates on the same fuse. So if your taillights work then the problem is between the taillights and the license plate bulb socket.
