HELP !!! Any suggestions

[mcubedntx]

Ok here is the problem. Both of my vents in my kick panels are horrible. I drilled the spot welds and opened them up from the outside. The passenger side looks repairable, however the driverside is totally shot, I mean totally. The whole kickpanel is eaten up. What would happen mechanically to my AC system if I closed the driverside vent up totally? Does the cooling sytem require both vents to work properly? I may anap a few pics tomorrow and post them. My motor on my compressor went Kaplooey tonight , so I got make a roady tommorrow.
