Service bulletins for the 2016 GMC Canyon

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.

GCUS-3-7162018-04-02. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. 16019 - Customer Satisfaction Program. Some vehicles may have a condition in which a crack in the heating and cooling module temperature door control shaft may form and result in inconsistent air discharge temperature control. If the shaft cracks, the air discharge temperature may be up to 33 degrees Fahrenheit (20 degrees Celsius) cooler than the requested values, depending on the HVAC mode selected. Inspect the temperature valve control shaft for cracks. If the shaft is intact, install a reinforcing clamp around the temperature valve shaft to prevent the shaft from cracking. If more than one crack is present, replace the temperature control valve.
PIT55252017-08-15. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. This Preliminary Information communication provides information to the technician about vehicles that have poor air conditioning performance above 80 Degrees Fahrenheit. Technician will need to ensure that the system charge is correct. Technician should be advised that engineering has determined that there may be two issues that could cause the concern. First the technician will need to monitor the High and low pressure with manual gauges and Global Diagnostic System 2 monitoring the AC Compressor Solenoid Commanded % in the ECM /HVAC data. If the pressures start to equalize but the Commanded Compressor % returns to 100%, turn off the Air Conditioning using the switch and then turn it back on or shut off the engine and restart it. If system begins to blow cold again and the gauges recover to normal, replace the Air Conditioning compressor. Second the technician should monitor and record the Heater-Vent-Air Conditioning readings. If it is found most of these readings are in specification but the low side pressure is at the low end of that specification and the Evaporator Air Temperature Sensor reads approximately 10 degrees or more higher than the technician should infrared thermometer measure the temperature of the 2 locations, about 2 inches in from the edge of the core of the condenser. f there a difference of more than 10 degrees Fahrenheit top to bottom, replace the condenser.
PI14402017-08-15. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. This preliminary informational bulletin provides technicians with diagnostic tips for a customer concern of odor emanating from HVAC system.
