CREW EXPERIENCED A CABIN DUCT OVERHEAT WHILE EN ROUTE. PASSENGER COMPLAIN THAT THE AIR CONDITIONING WAS NOT FUNCTIONING CORRECTLY. PASSENGER STATED IT WAS HOT IN THE CABIN. CREW SWITCHED TO THE ECS PAGE AND NOTICED THE TEMPERATURE WAS 84 DEGREES AND RISING TO 102 DEGREES. CREW FOLLOWED THE QRH CHECKLIST FOR THE CABIN DUCT OVERHEAT. QRH HAD THE CREW PULL BOTH BLEED CIRCUIT BREAKERS CAUSING A LOSE IN CABIN PRESSURIZATION. CREW THEN DECLARED AN EMERGENCY TO EXPEDITED A LANDING. AIRCRAFT LANDED WITHOUT INCIDENT. TROUBLESHOT THE SYSTEM AND FOUND THE CABIN TEMP CONTROL VALVE WAS STUCK IN THE OPEN POSITION.

FLEW BY TOWER TO VERIFY THE ORIENTATION OF THE NOSE WHEEL. TOWER REPORTED NOSE TIRE WAS ABOUT 30 DEGREES OFF OF CENTER LINE. ATTEMPTED TO CORRECT BY ABRUPT CHANGES IN ACFT ATTITUDE. MANEUVERS HAD LITTLE EFFECT. AFTER BURNING EXCESS FUEL, LANDED WITHOUT INCIDENT. A BRIEF VISUAL INSPECTION REVEALED THE NOSE STRUT WAS LOW ON NITROGEN CHARGE, WHICH WOULD LEAD TO THE INCOMPLETE NOSE STRUT EXTENSION AND THE SUBSEQUENT MISALIGNMENT OF THE NOSE WHEEL.

DURING APPROACH THE PILOT PUSHED THE APPROACH KEY ON FMS AND THE COURSE INDICATOR CHANGED FROM PINK TO GREEN. ON PASSING THE FAF AND WITHOUT PILOT INPUT, AT ABOUT 2,400 FT MSL, THE INBOUND COURSE CHANGED FROM THE INBOUND COURSE IN ILS 12R TO THE INBOUND COURSE OF THE ILS 17R COURSE AT LAST AIRPORT.
