I have a 2012 Suzuki Kizashi. Up till now the heat and air have ran great. This past summer the AC started working intermittently. It would sometimes quit while driving. I could turn the unit off then restart it and that would fix the problem or it would help if the temperature was adjusted up or down. The heater is doing the same thing. I have heard people post about fuses or the radiator cap being the problem. All during this I have never seen any leaks. Any suggestions or tips would be greatly appreciated. I am taking it to a dealer soon and would like not to spend an arm and a leg. Thank you for your help.
