## Discrepancy

PASSENGERS COMPLAINED OF BOTH EXCESSIVE HEAT & EXHAUST ODOR.  AIR FLOWS FROM BOTH COCKPIT & CABIN, WEMACS VERY LOW FROM ENGS ONLY, IMPROVES WITH APU ON LINE.   WHEN AN INFLIGHT APU START WAS ATTEMPTED THE EXHAUST GAS ODOR WAS VERY STRONG.  COMPLIED WITH APU, LT & RT ENG RUNS.  COMPLYING WITH AIR CABIN & COCKPIT COOLING & HEATING, NO DEFECTS NOTED AT THIS TIME.  DID NOTE EXHAUST ODOR IN CABIN PRE APU & ENG RUN, BUT NOTHING DURING RUN & OPS CHECK.  NO EXCESSIVE HEAT NOTED IN COCKPIT IAW MM 21-60-00.
