Right turn signal not working...

Right turn signal not working...it blinks once like it wants to work but then it stops blinking. The right turn signal indicator flash briefly once...as well as the front and back lights. Therefore the bulbs still work. Left turn signal indicator and bulbs work fine. When I hit the hazard light button, only the blinkers on the left side work (front and back) Any ideas?

A bit of history...I recently had some car trouble and had to pull my car over to the side of the road. I turned on my hazard lights until the tow truck arrived. After several hours, the hazard lights drained the battery and stopped blinking. That was the last time it all worked perfectly. Could there be a short somewhere or a problem with the alternator?

Any assistance would be greatly appreciated.
