Be sure the dash light dimmer switch is not turned off and the fuse is okay and the bulbs are good.
Be sure the bulbs are not blown.
First check the fuse, then the bulbs, then the flasher relay, then the signal switch.
There are a variety of issues that can cause the tail lights to stop working in a 1993 Chevy S-10 pickup. There may be a blown fuse, a damaged wire, or the bulbs may be burned out.
remove the trim panel around the instrument cluster then remove cluster. On the back of instrument cluster are the bulbs just turn them half a turn and they come right out.
I believe that the first digital cluster on a S-10 Blazer was in 1989.
It is important to have working brake lights on a vehicle. If the brake lights are not working a person should first check the fuse, bulbs and at last the wiring.
What dash board lights? The ones for the ac controls? the lights to the dash cluster?Go to a auto parts store get the lights. If they are for the dash cluster you will need to get 10 I believe. you have to completely remove the dash cluster once it is out of the truck all you have to do is turn and pull out the old lights and put the new ones in. If you talking about ac controls there should be a total of 4 same thing once you get the dash apart turn and pull the old ones out and put the new ones in. Before you do this, make sure that you disconnect the negative cable on your battery and wait about 90 seconds, since you are going to be working around the AIRBAG and could set it off by accident!!!!.
Head light fuse is 20 amp
Headlights? Brake lights? Tail lights? Signal lights? Courtesy lights? Dash lights? Check engine lights? Need more info please.
Sounds like your ground source is weak, the gauges don't work with the lights on because the illumination circuit is using all or most of the ground, I ran into the same problem on the identical vehicle. Restore a proper ground to the cluster and it may cure it. (I put a separate ground lead from the dash to the ground circuit on the back of the cluster).

If both the odometer and the speedometer do not work it may be the speed sensor in the transmission is bad. If only the odometer does not work it is probably a bad cluster.
