TEST FRONT RIGHT BLINKER CIRCUIT AND REPLACE THE BULB,,WITH PROPER BULB...A DOUBLE CIRCUIT BULB IN A SINGLE SOCKET WILL DO THAT ALSO A SINGLE SOCKET BULB IN A DOUBLE SOCKET HOLDER....CHECK LEFT SIDE BULB FOR ACURANCY

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.

More than likley your multifunction/turn signal switch is bad.All the lights you are talking about are tied to this switch.

OK try this, push and hold brake then push on the hazard switch if brake lights come on then replace the turn signal switch.
