Check the fuse panel and probe the fuses with a test light for that circuit. If OK, I suppose that none of the turn signal lights light up at all. there is a wire connector plug under the dash panel below the steering column that goes to the turn signal switch. With the key on and the turn signal turned on to right or left. Take and prob with your test light the wires one by one.on that plug. there should be one red or red and white strip wire that has voltage when the ignition is placed on the on position. when you turn the turn signal switch on to the right or left there should be two wires that have voltage and will be blinking. Then try the other side and re probe the wires and should be two more of different color wires blinking. It is very seldom that you will find a switch to go out and not have any voltage going to at least one side of the turn lights. But first check for the hot wire with the ignition. on the on position. Kinda hard for me to guide you on how to check this problem hop this helps good luck
 
Our turn signal went out and we checked all the bulbs and they are fine. We check the emergency flashers and they work fine as well. The only problem that I can think of is the wiring somewhere in the steering column or the actual turn signal switch. Any help here?
