## Discrepancy

PASSENGERS AND FLIGHT ATTENDANT'S REPORTED A WHIFF OF ELECTRICAL ODOR IN THE CABIN AT A ZONE, B ZONE, AND IN AFT CABIN NEAR ROW 25 WHILE EN ROUTE TO IAH.  THE ODOR RETURNED LATER WITH A VISIBLE HAZE.  THE APPROPRIATE CHECKLIST WAS RUN AND THE ODOR AND HAZE CEASED.  THE AIRCRAFT LANDED AT IAH WITHOUT FURTHER PROBLEM.  MAINTENANCE FOUND THE OEU (OVERHEAD ELECTRONICS UNIT) AT L-3 DOOR SHORTED.  THE OEU WAS REMOVED AND REPLACED, OPERATIONAL CHECKS WERE GOOD.
