    Anyone have any ideas on whats behind the A C box on the fire wall I want to take mine off and its connected to the heater , it's all one piece. Maybe I can take it off and cut it and put the heater side back on, anyone have any thoughts. I've already taken my compressor off and want the rest off...

    Your defroster is equiped w/ a dehumidifier which is all part of the A/C firewall unit. You can yank it all out. Just make sure your vent/heater/ defroster diverter works afterwards, generally operated by vacuumm source.

    You pull it off, you may as well pull the innards out too, because you'll no longer have a heater. FWIW.

    To loose the box you going to have to find a non A/C truck and get both the inside and outside box. If you look the blower is on the fender side and ALL the air goes through the outer box then goes into the truck. Then a diverter either sends it to the heater core or to the vents. On a non a/c truck I thing even the heater corr is in a different location and the hoses connect about 10 inches towards the motor.

    I want to take out my AC box and its connected to the heater box(its all one piece) and was wondering if I could put a cover from an old heater box on instead of the one thats on there, or if I just have to cut them apart.I was also curious as to what was behind the AC box, is there a giant hole in the firewall or what, see its getting confusing isn't it. I thought I could just take out the AC and put some diamond plate were it used to be but now I see its directly connected to the heater.AHHHHHH.....[​IMG] POS PITA[​IMG]

    Thanks Dorian, and eveyone else, looks like I'm in for more than I bargained with but what a better time to tear apart your heater than in mid October....[​IMG]
