Question about 1987 Chevrolet Blazer
The fuse should be labeled Tail Lps in the middle of the fuse block. It should be a 20 amp fuse. If it is blown, turn on the tail lights after you replace it and see if it blows again. If it does then you have a short that needs to be fixed. Usually what happens is that the wire is rubbing somewhere and has chaffed through. Alittle black tape will solve that problem. This would also apply if you get a few days of driving before it blows again. To find the problem remove the light sockets and drop them down under the truck and check them over looking for cracks or bare spots in the insulation. Tape any suspicious spots.
If the fuse is good replace the bulbs. If that doesn't work check out the ground wire.Take it off,clean it up and reattach it, making sure the chassis is bare shiny metal. It could also be the sockets themselves,or the plug-in. The plug-in is on the driver's side near the bumper.
