98 ZJ factory service manual (A/C question)


Does anyone have a 1998 Grand Cherokee factory service manual? I would like to know if there is a valve or flap that switches between the heat and the AC in the airbox under the dash. I can see that both the coolant (heat) hoses and the AC lines go into the firewall(airbox) seperately.
I have my dash apart 9most of the way) so that I can see the airbox and that all the flaps (defrost, upper, lower, etc.) operate properly. The fresh air/recirculate flap also works. So I think the problem may be inside the airbox. When the compressor is on ICE actually forms on the outside of the line that goes into the firewall. So I don't think it is low on refrigerant.
Can anyone look in the FSM for me? E-mail me if you can scan a couple pages and e-mail them to me.
(I sure can get hot here in GA)

Thank you,
