i unplugged the climate controls and the vacuum lines, i know i am stupid. now when i plugged everything back in and the controls are set to off the air blows through the defrost vents and you can control the fan speed, when you turn it to the face it blows correctly, when it is on face/feet blend it works but than when you turn it to feet it is off and the feet/defrost and defrost positions dont blow any air but make the compressor run, please help!!!! I have a 2004 grand cherokee. I tried turning the knob to feet since that was the off postion and plugged everything back in and still everything is messed up, please help so i dont have to go back to the dealer.

Just a guess but maybe you got the lines plugged in wrong...
