When a/c is on, the driver side is blowing out cold air but the passenger side is blowing out hot air. both sides are set for a/c...for example....60 degrees auto a/c, turned up high, but the passenger side vents are hot although the drivers side vents are cold. the rear vents are blowing out totally hot air.....
help.
The problem is most likely a bad dual climate control valve. This component is located on the right side near the radiator under the hood. It will have several coolant hoses hooked to it and 2 silver cylinders protruding from it. You can clamp off the heater hoses at the heater core and see if both sides cool then and this will tell you that the valve is letting coolant thru when it shouldn't be.
This will narrow it down to either the valve or the control head inside the car,or wiring in between them. The only way to narrow it down further is if you have a scan tool that could access the climate control data. Have seen several of these valves cause this concern and have only seen one control head cause it.
This is what your looking for !
