My air conditioning in my Camaro ss 2012 is blowing hot on the left side and cold on the right. Anyone knows what the problem could be??

  • Well everything is fine if you're getting hot air, but you must have a vent pipe unhooked, that'd be my guess, so your feeling the air from outside – user38183 Jan 5 at 7:12
  • Welcome to Motor Vehicle Maintenance & Repair! It's more than likely a blend door motor which is stuck or dead on the one side. – Pᴀᴜʟsᴛᴇʀ2 Jan 5 at 15:54
  • @Pᴀᴜʟsᴛᴇʀ2 This would require that the HVAC system has two blend doors (one of each side of the car, along with a separate cold air feed on each side) to make the hot/cold adjustment. Have you seen such a system? A simpler design (seems more attractive to me, engineering-wise) would have the heated and unheated air streams join just downstream of the heater core, with a single blend door at the apex controlling airflow mix. I'd want to check for a loose vent pipe, as suggested by hello motto. – David supports Monica Jan 6 at 0:02
  • @David - That's the way most systems these days are designed ... if they have dual zone HVAC ... passenger and driver side is completely separate. I'm talking a lot of vehicles are setup this way. – Pᴀᴜʟsᴛᴇʀ2 Jan 6 at 0:42

    @darune I don't know what "central A/C controls" means. If there's no ability to adjust heat differently for the driver and passenger, then I'd say the car has a single system for providing heat, and as you describe in the other thread, it's not working correctly. Because it works initially, and then fails, I think there's an obstruction in the plumbing which carries coolant to and through the heater core. I'd make sure all the heater hoses are free of internal obstructions, and that the heater core itself allows coolant to flow. – David supports Monica Mar 28 at 19:29
