Hey Guys. New here, but have read a lot of threads on vacuum issues. I need someone to please post some photos of their vacuum line that goes from their heater control valve to its destination. I believe it may go through the firewall and other threads on here do not give a definitive answer. Also i would like a photo of the check valves near the battery. Any help would be nice. My Ac is defaulting to defrost and it doesnt get cold and it used to get pretty cold in there. Looking forward to photos. Thanks.
