So, bear with me here. I am a new owner of a used 2014 Enclave with only 39000 miles. I live close to the Dallas area in Texas and recently purchased this vehicle. When test driving it, I noticed that the a/c wasn't very cold, especially in the rear. I asked the salesman if it was a problem and was told that it takes a while for it to cool down. I know that sometimes it gets real hot here, but so far it is only in the upper 70-low 80's. Before I bought it, I again asked the salesman to have the a/c checked for leaks and charge. At delivery, was told everything checked out just fine. Have driven it to work twice now and both times, on the way home, it doesn't seem to cool very well. I drive 25 miles, at highway speed, every day. I drive too other vehicles and both cool better than this one. Both are approaching 200k. Does anyone else have this concern or is it normal.

Low Air Conditioning Refrigerant Charge
August 26, 2015
Some 2013-2016 Traverse, Enclave, and Acadia models may have warm air conditioning. A check of the refrigerant level may reveal a very low/empty charge. After performing normal diagnostics, if the source of the refrigerant leak is not found, check for a small refrigerant leak at the rear auxiliary air conditioning evaporator.
Engineering has determined that dust from the blower motor brush on the evaporator may have some copper particles in it, which causes accelerated corrosion to the evaporator. The copper particles are coming from the blower motor during the motor break-in period, so the motor does not need to be replaced.
Remove the rear auxiliary blower control module and insert the GE 50078 Electronic Leak Detector to test for a leak. If a leak is found, replace the rear evaporator.
Also remove the rear blower motor and blow the fan and blower cage (Fig. 9) with compressed air to remove any copper particles and dust that could be redeposited on the new evaporator. This will prevent the possibility of a subsequent failure of the evaporator from the copper dust remaining on the blower fan cage.
