I had a '92 Corsica that had that problem, it was the weather stripping along the door that was causing the problem. If it doesn't seal properly, or if the weather stripping is coming loose in some place it won't work as well as it should.
Many Ford escorts have that problem from a leak where the rain water is not draining completely from cowl area and dripping into the vent system around the blower fan on the passenger side. I also saw a Chevy cavalier with a wet floor from the a/c condensation not draining & it was overflowing into the passenger area.
Our 1999 Grand am had a small pinhole in the floor allowing water to come up under the carpet. Pull your carpet back a little and take a water hose spray under floor boards see if you can see water coming in.
well many of the older cars have drains from the vents they can be difficult to locate but look at the bottom of your wind shield and remove the plastic cover that covers the air filter take a vacuum a suck it all out pour a glass of water in there well not into where the blower motor is just at the base of where the filter was a see if the water drains out if not the drain is still plugged and that is how the water is getting in it floods the compartment and backs up in to the motor shroud and in turn leaks out onto the passenger side floor so try an air hose or just keep on vacuuming until you find it good luck
check sunroof for leakage
better check your heater core.
you left the window open stupid!
Windshield seal? Lower door seal? Hole in floor ?
It probably has a leak in the heater core.
You probibly have a bad heater core.
Assuming that the window is rolled up, you must have a bad rubber door seal on the passenger side.
Check to see if your floorboard is rusted through. If it is patch it.
You have a leak. Possibly the drain lines are stopped up or the leak is at the windshield.
If it's the front passenger side ,I would say your heater core is leaking .
One reason your floorboard is wet after it rains is that there may be rust holes in the floor or the floor pans are rusted out. A leak in the windshield seal may also be the cause of wet floorboards. Bad door seals or window seals can allow water to soak the floorboards when it rains.
the wet side is where the sun cant get at so its rains there and doesnt really dry
If it is wet with engine coolant you have a leaky heater core.If it is wet with water you have a plugged AC condensation drain.
some pump underneath the passenger side floor is clogged. unsure of what pump it is though. Mine was like that too. Cost around $200 to fix.
If it rains, then it rains. If it rains, things on the street will get wet and anything not protected from the rain will get soaked or wet.
Water on the passenger side floor would be a plugged up AC drain. The drain is located under the hood, at the lowest point on the HVAC box on the firewall. However if the floor is wet with engine coolant, the heater core is leaking.
Well, if your experience is anything like mine, your heater core is gone. Take it to the shop.
Check for a sickly sweet smell. The heater core is probably leaking coolant into the floor. The core is not repairable but can be replaced.
Is it blood, oil, water, or urine?
because at the bottom of the door its is a black plug pull it out and all the water will drain out of your door
I had the same problem with our 99 venture we found out that the drain hose for the A/C had come off and was draining inside the van.
Check the undercarriage for rust holes. My Bonneville would flood when it rained because of a small hole in the passenger side rear wheel well.
It's a Dodge thats why.
check your blower motor, located under the dash board. its on the passenger side. if the leak is on the drivers side, i have no clue. but my hubby's car is leaking water from the blower motor on the passenger side. found out at the car wash...
