2005, 2006 HUMMER H2 HVAC Orifice Tube

Subject:2005, 2006 HUMMER H2 HVAC Orifice Tube

Models: 



An issue that was recognized on the 2003-2004 H2, where some vehicles had the HVAC orifice tube installed backwards, has long since been corrected.

This condition does not exist on the 2005-2006 models; however, we continue to receive warranty claims. When diagnosing an HVAC complaint, the orifice tube is not one of the items that need to be checked on a 2005 or 2006 model.
