I have A 1987 jeep wrangler. It keeps blowing the fuse on the turn signals only

Start at the most obvious source, the bulb sockets. Not sure weather these are duel filament or single but in every case the + side of the bulb is the point(s) on the bottom of the bulb and the ground is the cup (housing) itself (on 1156/1157 bulbs). There is suppose to be a plastic or rubber insulator between the cup and the + lead(s). In many cases (especially in jeeps that see wet off road use) the cups get corroded or the rubber (plastic) degenerates and the wires come in contact with the bottom of the cup (which is the ground) and short.
After that it's follow the wire(s) to some place where it's making contact with the body somewhere.

As for your 4-ways. Try switching the new turn signal flasher and the 4-way flasher around in the fuse box. They should be the same. If it fixes the problem then you need another flasher. I would suggest spending the $8 or so and upgrading to the solid state flasher units. They will last allot longer and take more abuse.

That's about all I can suggest at this point. I wish you well. I know how wiring problems can be a headache.

when they are turned on? the right side I have replaced the the flasher. also the 4 way's don't work. I know that I have A short some where but not sure where to start.
 
Sure sounds like a short. The first place to start looking is the easiest places to look. Check your bulbs and connections on the right side front and rear. Also check the wires where the go through the light housings.
