2005 GMC Savana 1500 Passenger

Issue: 
On certain vehicles, an unused wiring harness for a rear HVAC blower motor, located in the left B-pillar area, could become damaged if exposed to moisture or contaminants. If this happens, the wires could short circuit.
Note: This recall only affects cutaway chassis incomplete vehicles.  

Safety Risk: 
A short circuit can create the risk of a fire. 

Corrective Actions: 
General Motors will notify owners by mail and instruct you to bring your vehicle to a dealership to seal the wiring for the rear HVAC blower motor at the left B-pillar.

Certain full-size passenger, cargo and cutaway vans may have front and rear seat belt buckles that will not latch or will not unlatch.  There are two conditions that render the buckle inoperative after customer usage.  Specifically, (1) with a damaged ejector hood, the latch tongue cannot fully enter the buckle and will not latch, and (2) if the release bar moves permanently out of position the buckle will either be unable to engage the latch or the pushbutton will be unable to unlatch the buckle.  Correction: Dealers will inspect buckles and, if found to be inoperative, the entire buckle assembly will be replaced.  Note: This is an expansion of recall 2005390.

On certain vehicles, the hydraulic brake booster's pressure accumulator may crack and/or separate from the Hydro-Boost assembly during normal vehicle operating conditions.  If a separation occurred and the hood of the vehicle was open, fragments from the accumulator could cause injury to people in the immediate area.  In addition, the presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly.  The loss of fluid would cause increased steering and braking effort.  Correction:  Dealers will test and, if necessary, replace the Hydro-Boost assembly.
