This information applies to the 2004 Cadillac XLR and the 2005 Chevrolet Corvette and newer.
Use special care when removing or installing the HVAC module for service. The HVAC module is seated between a non-removable upper and lower tie bar
(fig. 11 - attached). The HVAC module must be partially disassembled before removal and installation (fig. 12 - attached).
Refer to SI 2000 to obtain the service procedure for correctly removing and installing the HVAC module. Failure to do could result in damage to the HVAC module.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
