Got some problems with the HVAC systems not cooling right and heating also not working correct. All of the sudden the vents aren't working right - drivers side in Heat mode doesn't put out heat (cool air) but passenger side has very very little heat/warm (not Hot air), then when the A/C mode is on the same results driver side vents just air (not Cold) and passenger vents are cool (not ice cold). I've looked at some of the inner workings like - fuses, actuator controls, heater control valve all seam to be in working order. It's the something I'm not seeing problem is beating me up. HELP !
