One of your warmers are shot test with a voltage meter to see if there is a closed circuit

Yeah unplug the hand warmers one at a time and use an ohm meter to measure the resistance in them to see which one is bad.I can't remember right off the top of my head what the ohms are for the grips but if one of yours is way out of wack from the other one then you found the problem.
