Hello, I have a small problem....lol 2003 ram 1500. 5.9 gas 2wd.4 door. driver side 2 vents blow at 53 degrees, the passenger side 3 vents blow at 81 degrees. the air blows hard at all vents , The recirc. door is working properly. I bypassed the heater core hoses . now the passenger side 3 vents blow at 71 degrees . recirc. is on and fan speed is one click from full. When changing from hot to cold settings the lever is fulling opening and closing. it does pause in the middle of its movement. Is this a blend door problem.Shouldnt all vents blow cold now that the heater core hoses are disconnnected?
