I thought my 2014 Silverado A/C was bad. I just realized that my passenger side vents are blowing cold when my drivers side vents are blowing warm. I guess it's been this way all summer because everyone riding in the passenger seat has complained of being cold while I've been hot so I thought they were crazy. I've added freon and taken freon out and nothing helped. I don't know about the battery reset because I put a new one on about two weeks ago. I am going to disconnect it and pull the fuses to see if that helps.
