I've had this happen a couple of times in the last few months. While turning ice cold water will run out from under the dash on the passenger side of my truck. This usually leads to whoever is sitting there to let out an expletive of some sort. Lately I have noticed a distinct sloshing sound when turning it seems to be coming from the same area. Any ideas? Could the drian be plugged? If so what is the easiest way to get to it to blow it out?

I'm having the same problem with my truck. I've read all the threads I can find but I still can't find the drain hole. I will keep looking and if I find anything I will let you Know. I have a feeling the drain is behind the wheel-well cover.

 

The condenser is in front of the radiator. It certainly isn't leaking.

Your evaporator drain is clogged. You have to get underneath the truck and find the drain. It will be near the base of the firewall and will likely be above the exhaust.
