After jumping my chevy s10 no dash light , no tail lights.

SOURCE: 1996 Chevy S10 4x4 - Dash lights need replacing

not easy, you have to remove bottom plastic from underneath the dash, there should be two or three you don't have to go to the passenger side, then the front contour snaps off bring your shifter arm al the way down to 1st gear and the steering colomn as well on that plastic contour you have the 4x4 switch to unplug, rear wiper switch, light switch, and rear hatch switch, wiggle the plastic out, now you should see the instrument cluster there should be two to 4 screws holding that in should be 7 mm screws, now careful, if you have the analog cluster you have the speedmeter cable in back to unclip, if digital odometer it's plugged in directly into the dash and there could be an additional plug on top of the cluster, if the cluster came out unclip the backing and you should see the back of the bulbs but careful some are twist off and many others are soudered on that board you aoto parts counter should have these lights in stock no sweat.... good luck

SOURCE: No tail lights

Try checking the headlight switch it may have broken contacts in it. Easy fix go to a salvage yard find same make and model truck, swap headlight switches.

SOURCE: no lights

check the park lamp relay and the body control module for possible causes. the body control module controls both systems.

SOURCE: No tail lights on 1991 Chevy Silverado. fuse is good

sounds like a broken wire in the harness. look around the bumper area,sometimes along the frame. may have to peel back some tape covering. also if you have a trailer harness look closely at those.

SOURCE: Have no dash lights and brake lights.

the first thing you should check are your fuses. it sounds like that might be the problem
