'02 Saturn L300 - water leaking inside of car?

Howdy-

My sister's L300 has a leak in the driver's area right in front of the gas pedal. The puddle doesn't mimic the rain patterns here and it's been bigger than usual during the recent 90 degree days.

Instinct says it's condensation from the A/C and not a hole in the floor - is it likely that something is broken (a broken seal, for example) or could this be the result of a clog at the opening of the pipe that normally discharges the condensation build-up?

Sound familiar? Any hints/tips/ideas of how much is involved to fix it (if this is the problem). It's not a huge deal but heat+damp will equal mold soon (it's already musty in there).

Thanks,

Chris

Generally those leaks are on the passenger side, but it's the likely candidate. When running the a/c do you get a good discharge of water under the car from the drain?

Your instinct is right. Most likely the drain for the evaporator is clogged and instead of draining beneath the car, the water is filling up the bottom of the AC unit. The drain is generally located on the firewall, either on the right side of the car near the evaporator, or like my car, in the center. It could be as simple as a rubber elbow (like mine) or a small section of drain hose that's either stiff like a heater hose or soft like a bladder.

Pull the drain hose off and see if it's clogged totally, if so then cleaning it out is fairly easy. If it's not clogged completely, then try to see if you can feel into the drain opening for hard water deposits or other debris that could be blocking it.
