Question about 2001 Pontiac Bonneville

We have water in right front and rear floor. We have had the doors checked, the air conditioner lines were changed. The water comes in while driving in the rain, but does not drain out. There is about 4 inches of water. No service dept. can find the problem.

Remove all 4 door panels and check the plastic sheet water deflectors, This layer of plastic is necessary to keep water from running into car. Pay attention to the bottom edge and up about 8 inches on the front and back edges. if there are any bubbled or loose sections, they need to be sealed using a body grade sealer(No Silicone)

2009 Chevy HHR water in floor passenger side front and back after heavy rain car was just sitting all day not driving where did 2 inches of clear water in floor come from,


The high-level intake at the base of the windshield directs rain water through channels behind the door pillars to the street. If the channels become clogged with leaves and debris, the rain water can leak inside.

Rear Floor Vent heat only


Sounds like your heater coolant hose door flap is broken or loose. May want to check behind the heater controls, if your components are mechanically operated. If electronically, may need to perform more troubleshooting before replacing this component.

1997 gmc rear air conditioner is blowing hot


Could be a blockage in the lines to the rear unit.
Might be low on freon too. Or a blend door problem.
Can you check under the floor and see if one of the lines is cold ?

2002 suburban has leak in driver side rear floor. Cannot see where water would be coming from?


We had same--water on driver side rear floor (soaked!). Driver side front floor seemed dry until feeling UNDER rug, was slightly damp. We found the location of TWO leaks causing this.

Leak #1 was through the parking brake line/cable seal; Recaulked with silicone. Removed plastic trim on floor between floor and door to reveal metal channel filled with water.

Leak #2 was where the door meets the car, near the hinge. It was the accordian-looking tube housing the wiring for the door. The big, rubber, circular plug connecting it to the main part of the car had come loose and water ran down through that, into the SAME metal channel filled with water from leak #1; will seal with silicone.

Note: We found that the channel filled extensively near the front door, BUT the carpet edge from the floor near the rear seat was dipping into it, wicking it up to the rear floor. Also, upon acceleration, the water in the channel gushed toward the back, thus soaking the rear carpet.

These leaks were found by removing all plastic trim (covering edges of carpet by doors), then one of us pouring water into specific areas of the exterior of the vehicle, and the other one watching closely with a flashlight for any signs of dripping.

I have water leaking on the right rear floor passenger side


Sounds to me like your issue is with condensation from your air conditioner. The condensation isn't properly draining, probably from a damaged or clogged drain hose.

Interior Carpet Getting Wet


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.
