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! :)

Have 1999 dodge durango, replaced the water pump,thermastate, now looks like a small leak on the passanger side sometimes, when the car gets warmed up the windows inside fog up, the defrost wont even clear...

Is your coolant level going down, on a regular basis, to the point that you need to add some periodically? If not, then lets say it's not heater core for now, and that dripping that you see on passenger side may be the drain tube from the heater box. Try to pinpoint exactly where that drip is coming from, and if it does look like a drain tube, try poking a pipe cleaner or something similar in there carefully to dislodge whatever may be clogging up that tube. My guess is that it's plugged up and that's what's also causing fog inside vehicle. Once that's drained out, things will dry up and you should be back to normal with a little luck. If your not sure about whether or not core is leaking, have a rad, or repair shop, perform a system pressure test, and that should tell you whether or not you have a system leak, then you can investigate further if necessary.

When air con on in my car water leaking down the front passanger side making very smelly carpet any way of fixing problem someone said drain need unblocking where is the drain

The drain is supposed to come out under the car, passenger side, ahead of the dashboard area. If yours is clogged, that's where you need to look once you're under the car. You should see a tube pointing forward or down, sticking through the firewall - that's it.

2003 Jeep Cherokee Leaks Water on Passenger Side

Just had ours fixed, look on engine side of firewall, if the outlet pipe in passenger well is a 3/4 inch long pipe projecting forward into engine bay with no tubing leading down towards the ground, the problem is water comes out trickles back with pressure in engine bay to foam seal under the pipe and enters footwell inside car.
Take a piece of rubber tubing and hose clamp it on and direct it down towards ground in engine bay and the problem will be solved!
We have gone from soaking carpet to no leak at all with this simple fix.

Sunroof leak

there are drain hoses on all all four corners of the sunroof. to access the front ones, remove the front inner fender liners. you'll probably see a plastic grommet/spout that the drain hose attaches to. in the rear, remove the trunk liners on the side. you should see the drain hoses running down the inside of the quarter panel.

Water leak on passenger side on 99 chevy s 10 not anterfreeze, leaks when not being driven

there is only one thing that leaks water there, that is the AC condensation drain, water forms as part of the AC cooling the evaporator core, this water must be drained away or it will flood onto passenger area, so there is a drain on the passenger side at bottom of firewall, will leak allot of water depending on how humid the air is.

There is a water leak somewhere in my 98 toyota camry that leaks into my passenger side floor. There is no sun roof and no visible leaks from the windows or doors. Any thoughts? A/C leak maybe? water...

I am the original owner of camry xle 1998 with wet floors. In 2000 I had drivers side door seal leaking at welt. Removed old door seal and new weather strip on drivers side installed. The door panel was never wet, but wet at bottom of door where there are drain holes...slowly leaking under carpet.
In 2001 later water again. Coming from overflowing A/C evaporator-drain plugged/ tank full of debris. Removed evaporator, cleaned + drain cleaned.
In 2003, driver door seal against window rotted. Removed door panel and found leak at window belt molding at the mirror joint inside + out. Lots of mold under carpet needed to replace! Made a fuss at dealers for reacurring problem and they replaced the carpet for free.

Leaking sunroof

Had same problem with 91 Prelude, after rain, water would leak from moonroof, especially when stopping, having a wet neck on the way to work is not fun! Solution was to remove the small screens and restrictor caps on the drain hoses. The hoses can be acessed through the trunk behind the quarter panel cover on either side, just have a can ready for the skanky water to drain once the plugs are removed. When all clear, the drains should drain out right behind the mud flaps in the rear on each side. There are fron drains as well, these run behind the driver and passanger kick panels and drain around the mud flaps in the front.
