it is in your fuse panel for the house..you must have tripped a breaker..does the outlet still work??? you need to run this off of at least a 15 amp breaker if the outlet is used with a short cord..if it is a long cord use a 20 amp breaker..but make sure the cord on the truck does not have a bad spot in it first and for most..dont want to start a fire

I have read in other threads that the cord from the front of your truck to the heater can get pinched/severed due to the way it is routed. Try following teh cord from the plug to the heater?

If it is just a resistor, then a longer cord of a given gauge will drop more voltage than a shorter cord, and thus deliver less power to the load.
