Have a 2003 Tacoma and today I was runnin the A/C and water was dripping on the passenger side floor. I know that they drip but should drip to the outside on the truck not inside. Something simple???? I just bought it as my 2000 didn't do it.

The outlet for the condensation might be clogged, maybe sneak under your truck and take a looksee.

that happened to me too! when I took it to the mechanic he fixed it in 2 seconds. open hood. on the right side there is a hole (not a hose) where the water drips out of. It was clogged with mud. The mechanic stuck his pinky finger (fifth digit) in and unclogged it. I hope this helps. Before finnaly going to the mechanic i lived with mildew and constantly sucking water out of my "carpet" with a shop vac for 2 weeks. I hope that this saves you trouble.
