Blower Motor Inoperative after Blower Control Module Replacement

After replacing the Blower Motor Control Module with part number 89019351 on some 2004-2007 Rainier; 2003-2006 Escalade models; 2003-2006 Avalanche, Suburban, Tahoe; 2003-2007 Silverado Classic, Trailblazer XL; 2003-2009 Trailblazer; 2003-2007 Envoy XL, Envoy XUV, Sierra Classic; 2003-2009 Envoy; 2003-2006 Yukon models; and 2003-2004 Bravada models equipped with automatic climate control, the blower motor may be inoperative. This condition may occur if the blower motor speed is set to any speed position, except for Low, when the key is turned off. Upon the next key on, the blower motor may be inoperative.

An updated blower motor control module has been released to address this condition. If this condition is present, replace the previously installed Blower Motor Control Module (part number 89019351) with the updated Blower Motor Control Module (part number 19260762).
