tamugrad2013 Posted June 8, 2018 Report Share Posted June 8, 2018 As I was running some errands this morning after my last stop the AC all of a sudden started blowing warm air on the drivers side and still cold air on the passenger side. As I went to the dealer immediately to make an appointment a I have the premium care warranty for another 5,000 miles until it runs out. The service tech recommended until the appointment I may be able to reset it by disconnecting the positive battery terminal which I was going to try when I got home. Strangely as soon as I leave the service desk and get back in the car the AC is working as normal again. I am going to keep my appointment but lets hope it continues to work until then.

enigma-2 Posted June 8, 2018 Report Share Posted June 8, 2018 Power glitch. Next time try resetting the HVAC conot roller by putting the system into the diagnosis mode. To do this, press the climate control power button and the defrost button at the same time, hold for a few seconds, then press the power button one more time. If you see 88 88 in the diplay, they system resets and all is good. 2 Quote Link to comment Share on other sites More sharing options...
tamugrad2013 Posted June 8, 2018 Author Report Share Posted June 8, 2018 Will do I know that this can be an issue according to previous posters. I did find the green connector under the dash and if it happens again I will try to disconnect and reconnect that and I also have placed my socket set in the car to disconnect the positive battery terminal if it comes to that. Again glad it happened before 100,000 miles. Quote Link to comment Share on other sites More sharing options...

tamugrad2013 Posted July 10, 2018 Author Report Share Posted July 10, 2018 Well interestingly when it was at the dealer they determined that a fault had occurred and the HVAC control module needed to be reprogrammed. Since that has been done their hasn't been a recurrence but then again it only happened once. Although another minor annoyance seems to have been fixed with this as well. If it was really humid outside which here it West Texas isn't to frequently the recirculation setting would turn itself off. We have now had a recent four five days of high humidity for us and rainfall (hallelujah) and the recirculation has stayed on the entire time. 1 Quote Link to comment Share on other sites More sharing options...
