## Discrepancy

A SMOKY ODOR WAS NOTICED IN THE COCKPIT AND CABIN AND THE EQ COOLING LIGHT ILLUMINATED WHILE ON FINAL APPROACH TO SFO.  THE RECIRC FAN SWITCH WAS TURNED OFF AND THE ODOR WENT AWAY.  THE AIRCRAFT LANDED WITHOUT FURTHER PROBLEM.  MAINTENANCE FOUND THE BLOWER CIRCUIT BREAKER POPPED.  THE MAIN EQUIPMENT COOLING FAN WAS REMOVED AND REPLACED AND OPERATIONAL CHECKS WERE GOOD.
