SOURCE: Water leak on driver's side - 2000 Mitsubishi Galant

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

SOURCE: Wet rear floor

Have you by any chance jacked up the passenger side, or got vehicle on a hoist to make sure there isn't any plugs on the underside that may have fell out? They could be round or oval metal or rubber plugs, probably in that area.

1999 Buick LeSabre has no cabin filter but leaks water onto passenger floorboard. Any suggestions?

If it has A/C the drain hose could be blocked and if no A/C it could be a leaking windscreen seal.

Why is there water on passanger floor after a heavy rain?

Check for leafs that are blocking drain holes on both ends . Air inlet cowl in front of wind shield. This blockage would cause water to back up and enter the Hvac air inlet.

Keep getting clear water in drivers side floor board, hasn't rained in days, is it something to do with the ac??....No holes found in floor board or firewall

Drain tube for your AC likely has debris or possibly a bug has made a home in there. Have it cleaned and see if it still drains.

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.

I have wet floor mats on driver side even if it's not raining

No, this is the A/C core drain hose. Check for leak or hose disconnected.

Water leak on the passanger side of a 1999 Jeep Cherokee Sport

The first place I would look is the floor board caps. Make sure one or more of them aren't pushed up, allowing water to enter the cabin. Also, because your defroster is probably on while it's raining, make sure the A/C drain plug isn't clogged. It's a small rubber fiting that sticks out from inside the firewall, behind the engine. Simply pull it out and clean it. When you pull it out, you might be surprised to see water coming out of the hole!

Just a couple things to check. I hope this helps! :)

Floor board wet drivers side. No drain tube for ac condensor. Not losing radiator water. Ac condensor not draing to outside. No tube on firewall. 4.2 dohc model

all of dodge models have a drain tube you'll find it over the rack n pinion on the right side passenger but you have to see when does the water comes in the floor board, when you use the AC or when it rains if it's the AC then it's you drain if it's when it rains then you have to check for leaks on your windshield or fire wall
