Leaks water when it rains or snows on the rug is wet on the drives side only

You may have a buildup of A/C condensate water in the A/C cooler box. Start the car up, and run the A/C; you should start to see water dripping out from under the car onto the street. If not, the A/C condensate tube may be blocked or dislodged from the A/C box. The water then leaks out of the box onto your floor. The drain is on the pass side, under the dash, close to the center console. The pipe goes thru the body. This is a very common issue.

It sounds like a plugged drain line from the air conditioner. Most cars now run in the a/c mode whenever u turn on the climate control (even when heat is on). The passenger side front is where it would be wet, and the carpet and carpet pad act like a sponge and will soak up the water. Let me know how u make out.

I was a manager at a Mitsubishi dealership.

There was a "secret warranty" on certain Galants where the firewall seam would fair and leak water into the interior. Call your local dealer to see if your vin qualifies. The fix is to simply reseal the firewall crimp seam with silicone sealant.

Alternatively, sunroof equipped cars sometimes get the drain channels clogged in time. Make sure to clean drain holes and use forced air if necessary.

Lastly, some cars have heaters with pollen filters. If those filters become clogged, condensation can accumulate and overflow into the interior.

If any of these solves your issue, please rate my answer

The AC evaporator units have a drain hose that runs through the floor because condensed moisture is a fact of life with AC units. Yours is plugged. You will have to get under the vehicle and look for the hose where it comes out, then take like coat hanger wire and clean it out, It is somewhere in the vicinity of where the passenger foot well meets the fire wall. If you have to raise the vehicle to get under it, make certain you have it safely supported. If you don't have the stuff, drive the passenger side wheels up on a good curb and use some cardboard to slide under.

The spare tire well is pooling water, check there. GM knows about it, but won't say it's a factory defect. Sorry, I'm in the same boat you are. See here: http://ww2.justanswer.com/uploads/Bluegorilla/2008-10-09_134337_08-08-057-001a.pdf
