Q: Water Leak on Passenger Side & Unknown Bearing Whirring Sound? on 2003 Toyota Corolla

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Hi- I have a problem with my 2003 Corolla. It just started leaking water into the Right Front and Rear Passenger wells. I put it up on a lift and removed the 2 Plugs on that side and it has drained out. I cannot find out where the link is coming from? I see under the firewall a small Tube coming out. Is this from the Condensate Pump? It is not plugged. Friend said it might be the Windshield or A/C. Not sure?\r\n
What can I do to fix this problem? I do not see any Toyota recalls for this year?

Also car is making a whirring sound when I start up and hit accelerator. Friend indicated it might be Bearings in Tensioner Belt? What can I do here too??

Thank you!

The small tube you see is the condensation drain for the heater/air conditioning housing. It is best to look for water leaks when everything is dry. First is the door seal or door, damaged in anyway? I have seen the seat belt having damaged the door seal on many vehicles. Do the doors close flush with body? Ensure the door seal makes good and uniform contact with the door (particularly important if the vehicle has been involved in an accident. You may need to pull back carpets pull back the carpets and sit inside the car (you may need a flashlight) and get a friend with a garden hose to spray water around the door jams to determine if the water is entering the doorway. Then spray water around the windscreen moving around the circumference of the windscreen. Look around the windscreen area and look up from the floor mat area (as best you can) to determine if water is leaking in around the windscreen seal. Is there any rust around the windscreen area or body work? If you have a sun roof there is a drain tube at each corner of the roof to channel away water. A blocked drain may cause water to fall from the sunroof area Water can also come up through the floor pan as you drive through water on the road, if any rubber bung or “seam sealer” has been disturbed or is missing.
Fan belt tensioners do fail on theses engines.
I had the same water leakage problem. Its because of the small tube where the front passenger seat feet are... here's a video that worked great for me. I have a corolla 2003 as well.

Were you able to get the whirring sound fixed? I also have that sound but dunno how to fix it.
