I replaced my water pump about 4 months ago and everything was working great. The last few days I have had hot air comming out the passenger side air vents while the A/C was working great in the rest of the vehicle. Today I get to work and I have a large puddle under my car from what appears to be water running out the overflow hose comming from the passenger side fire wall. My radiator is full and my resevoir is full of antifreeze.

water coming out the hose draining on the ground is normal when you have your a/c on. if it is particualrly hot and humid you will get more water. as far as the heat coming out the passenger side while a/c on you have a door stuck or not working. if it only did it once then it was stuck and just keep an eye on it. if it continues then it's got to be checked
