I'm having a really big problem with my turning signals. Whenever I turn them on, they only work for a few minutes then blow a fuse. I can't seem to figure out whats causing this for the life of me. Obviously there is something shorted out somewhere, but no matter what I do I can't seem to find it.... Any suggestions?

First, verify that the fuse that you are replacing has the correct rating. Someone could have easily stuck a 10 amp fuse in a 20 amp slot, because that's all they had. If the correct fuse is 10 amps for example, do not put a 20 amp fuse in the slot, hoping to cure the problem. You don't have some kind of electrical accessory that would be on while the signal lights are on, that is connected to the signal light circuit. If you do, the accessories load combined with the signal light function could exceed the fuse rating. If this is the situation, you'll probably need to find another circuit to connect your accessory to.

If that doesn't do it, make sure that all of the bulbs are the correct bulbs. I think that they all should be 1156 or 1157. Check a manual to be sure. Also, make sure all of the bulb sockets are free of anything that could short something out. If everything there is all right, try changing the flasher. I think that they are only a few dollars. It should just plug into the fuse block.

If all of that doesn't do it, you need to check the signal light switch. There is a possibility that it is causing the short, but I wouldn't think that would be very likely. I believe that you will have to remove the steering wheel to get to the switch.

If everything checks out, the short is probably somewhere in the wiring. You'll basically need to check all of the connections and all of the wiring that you can get to. You may be able to narrow the wiring that you need to check down though. Does the fuse blow when using the signal lights in both directions, or only one direction? If its only in one direction, we'll say left for example, you will only need to check wires that pertain to the function of the left turn signals. If the fuse blows in both directions, the problem is likely somewhere between the power supply and the switch, not in the wires going out to the lights themselves.

Cameron has some very good questions. However, I wouldn't start troubleshooting this by checking all the bulbs. Give some thought to the answers for his questions and it will help to narrow the problem down. His questions in a different order:
1, Proper size fuse installed? Yes/No
2, Problem occurs when stepping on the brakes without the turn signals on? Yes/No
3, Problem occurs with either the left signal on or the right or only one side?
4, Problem occurs with the hazard flasher on? (if you have one) Hazards work normally.
5, Running (tail) lights work fine and that fuse never blows.

Those guys are correct, but also I would check to see if a connector or wire is grounding against the body, It happen to me with a bad connector, shorted out whenever it turned on the turn signals...hope this helps, good luck Mike

John makes a good point. You should ask and answer the questions to yourself before you start the troublshooting process. This will help narrow the area that the problem lies in down some. I was just typing away and I wasn't thinking about the order of everything too much.
