What was found
ENROUTE TO FACILITY AFTER PICKING UP THE PATIENT AND A RIDER, THE CREW IN THE BACK ASKED, "CAN WE GET LIGHTS BACK HERE?" I TURNED ON THE CABIN LIGHTING AND THE LEFT CREWEMEBER SAID THAT THEIR OVERHEAD LIGHT DID NOT COME ON BUT THE RIGHT SIDE DID. SHORTLY AFTER I SMELLED WHAT REMINDED ME OF MELTING CRAYONS, A WAXY SMELL. I ASKED THE CREW IF THEY OPENED ANY MEDICAL PACKET OR EQUIPEMENT THAT MIGHT CAUSE AND ODD SMELL. I ALSO ASKED THE CREW IF THEY COULD SMELL IT. AFTER THEY STATED NO, I BACK TRACKED TO MY LAST ACTION, WHICH WAS TURNING ON THE CABIN LIGHTS, AND THEN I TURNED OFF THE LIGHTS. THE SMELL WENT AWAY ALMOST IMMEDIATELY. CONTINUED FLIGHT WITH OUT INCIDENT AFTER. INFORMED MAINTENANCE IN THE MORNING. MFG OF RESISTOR IS UNK.
