So I've been running around most of the afternoon with the ac on, and seem to have a lot of water draining from the drain tube in the firewall. It is dripping a couple times a second, and within just a couple minutes I have a dinner plate sized puddle and it starts to run the length of the rig. It is only around 80 or so today, and have been driving mostly highways. I know, or at least thought it was in need of a little charge. Would this explain it, or do I have some other issue in my ac that may be causing this? Thanks.
