You may have faulty wiring for your trailer lights. Look under the back of the truck where the wiring harness leads to the trailer wiring harness. Usualy it is a 3 way plug in the harness. Try unpluging the harness from the trailer wiring and just plug the other 2 wires into eachother
Hope this works for you!

You need to check for power coming out of the turn signal switch with a test light, or voltmeter. On older Chevys, the R/F turn signal wire is dark blue. Check the color of your wire at the bulb socket, then locate the turn signal switch connector, and probe that color wire with the ignition switch on, and turn signal switch in the right position. If you have power coming out of the T/S switch, you have bad connection, or open circuit between it and the bulb socket.

There is a short to ground in your tail/park light circuit. If your blazer is equipped with a trailer hitch, the first place I would look for the problem is in the trailer wiring. Otherwise, the circuits need to be traced from the fuse to the tail lights and/or all of the park lamps to find out where the short circuit is located. Whatever you do, DO NOT put a larger fuse in the fuse block. This will result in your vehicle burning to the ground. (I have seen this several times and it isn't pretty)
If you have a full-size Blazer, it should be a 20 Amp fuse. This fuse also powers your cigarette lighter, so check there also for a problem.
If you have an S-10 Blazer, it should be a 20 Amp fuse. This fuse also powers the courtesy/dome lamps.
