Hey, having an issue with my A/C in that it blows out hot air even when set to cold. I have run thru the diagnostics and get a result on code 54 - Vent (duct) sensor is open. From what I can see is that it's the white part in the picture is the sensor, but there is also that grey plug that was not connected to anything. Any ideas where that grey plug is for and where it connects to ?
