Service bulletin 7SB0030101A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

ON SOME COACHES INCLUDING THE 2000 AND 2001 MODEL YEAR ULTIMATE ADVANTAGE / ULTIMATE FREEDOM, THE CENTRAL A/C UNIT MAY HAVE A MISALIGNED SEAL BETWEEN THE EVAPORATOR COIL AND THE RETURN AIR INTAKE PLENUM BENEATH THE RIGHT REAR AREA OF THE COACH. A GAP IN THIS SEAL COULD ALLOW UNFILTERED OUTSIDE AIR TO BE DRAWN INTO THE AIR CONDITIONING DUCTS, REDUCING THE EFFICIENCY OF THE SYSTEM. A QUICK VISUAL INSPECTION WILL REVEAL WHETHER THIS SEAL MISALIGNMENT EXISTS ON THE COACH. *TT
