Water leaking inside the car.

Every time I use my A/C, I get water leakage on the passenger floor. I assume the drain plug is plugged up or something and is redirecting its drainage to the inside. Where does it usually drip out of so I can try to look at it to figure out the issue?

Here's some pictures of where its dripping:

I am afraid that my wife will have the same problem, I replaced her heater core and forgot to put that little extending pipe on the plastic tray that is under the heater core. Maybe you are missing that too, or someone did your heater core and did not seat right that plastic tray or that plastic trey is cracked.

Ah yes yes. I did take my car to a shop to have the heater core replaced... Where is that part located? Can I go from the inside of the car, under the hood or under the car?

under the hood, follow the two hater core coolant lines that connect to the firewall (somewhere in the middle exactly) the small elbow tipe plastic pipe should point downward somewhere just below and between the two coolant lines. The plastic tray has about one inch long pipe which may not be long enough if the plastic tray did not seat in right, or if the tray is cracked which is very likely if someone was not patient with the hidden bolts during the heater core procedure. My suggestion put news papers under the plastic tray and look for drips

Your accumilator and the lines will have condensation on them and drip occationaly in that area under the car.

As for the interior leaking hopefully its just the drain and not a leak in the coil inside the heater core box. They can get damaged while replacing the heater core. :eek7:

Here is a pic where the drain is located...
pic is of a 99 but all are in the same spot.
