I have a 94 Montero SR with the 3.5l. The problem is I'm in vegas on vaca and my A/C cant keep up with the 115 temp. I bought a recharge kit but for the life of me cant find the low end port. The high end is plain as day in front of the radiator. I've traced the large tube from the firewall to almost the compressor and no luck. HELP PLEASE!! WE'RE ROASTING!! thx in advance.
