AC drain hose stopped up somewhere, probably under the vehicle. Sorry I don't know where it comes out of the firewall or fender.

The drain plug is clogged in the bottom of the blower box. Condensation from the evaporator is building inside.

You have a leaking heater coil. Heater coil uses the radiator coolant as the heating media. Are you losing coolant in your radiator?

This means your air conditioner drain tube is clogged. This will take about a hour shop rate to repair or if you look behind the glovebox you will see it. Thanks

SOURCE: leaking moonroof onto passenger floor

I would lean more towards one of the drain tubes being disconnected. You will have to get into the headliner to check. Your leak is in the front, I would remove the sun visors and the trim on the windsheild pillars, this should allow enough room to see it the drain tube is loose. The drain tubes usually push onto a nipple at the front of the track, if it's loose just push it back on and secure with a zip tie.

Water on floor passenger side after it rains and after air has been running 2000 grand prix


Ac hose leak?
leaking heater core?

Hint: it leaks when it RAINS

If it were related to the heater core or the AC drain, it would be leaking when it is not raining also, so those diagnoses are not logical.

The grand prix has a long history of floor leaks from seal failures around the air intake under the windshield cowling, where RAIN water runs in.

Where are the chassis drain plugs on a 2003 Pontiac bonneville? My car leaks in the trunk and onto the floor on the front passenger floor


Your trunk leak most likely is rubber seal that runs the perimeter of trunk when trunk lid is open. Leak on pass floor can be a combination of things. Heater core or if car has sunroof, there is drains that run down windshield posts. Carpet will be wet and sticky if heater core is leaking (not to mention coolant level low) If it's sunroof drain, car has to be put on a lift and drains blown out with compressed air.

air conditioner/heater compressor's or evap canister is leaking on the floor. It is very common with the focus. After time that water begins to stink! Try silicone to seal the leaky component which would be above the floor mat.

Water on passenger floor...


Two things: If there is a stickiness or sweet smell to the water, your heater core may be leaking.
If this is just a summer thing, your a/c evaporator drain tube my be blocked/clogged or leaking inside the vehicle.
