Locate AC drain line

ac drain pipes are on the passenger side front floor area (just about where your feet go) under car when cars heater core gets a hole in it lots of times antifreeze will leak inside car on floor try to get a small sample of fluid thats leaking out with a tissue or something (white In color) see what color fluid is ,see if fluid is slippery like oil or not (rub it between fingers)
Antifreeze= orange or green in color
Transmission oil = red or brown
motor oil = brown to black
washer fluid = Blue or drk orange
ac condesate= clear water (cold)

Water leaking on pass side under heater box. Not antifreeze just when raining no it's not the windshield checked it for leaks.

If the AC is not on when it leaks during the raining, AND you are SURE it is not the windshield....It can only be coming in from 1 of 2 other places...your firewall or the firewall break...Somewhere towards the center of the firewall, a rubber grommet is missing or torn or loose, allowing the water to enter...Or you have a leak along the firewall brrak area at the top ridge that goes from the drivers to passenger side in that vented looking area where the wiper and / or fresh air door for the AC is located.

Two leaks on the front passenger quadrant of our 2007 Sienna

Water is conensation from the air conditioning system. redish oil is most probably a antifreeze leak, does it look like a redish water? If so then its antifreeze toyota uses a pink/red long life anifreeze. most likley from a water pump which is right in that area

Water in the passenger floor board of my 2005 chevy cobalt

check your heater coil under the dash on passanger side for leak at joint areas. it could be condensation from the AC condencer dripping down the line that goes into the firewall, if so seal that area with a good sylicone.

AC leaking water inside

You can normally find it sticking out of firewall area on passenger side, but some are even lower but should be in that area.

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.

2003 forester - there is water leaking in the front passenger side floor when the air conditioner is running. sometimes a hissing sound also in the same area.

You need to clear the condenstate drain for the AC evaporator core, it is under the car, as far as the hissing, sounds like a vacuum leak, look for a disconnected small hose around the area of the noise.

TOUCH DOWN with leaky ac into passenger compartment solved!
Discovered on left side of firewall of trailblazer a series of ac hoses leading into compartment. Bottom left area are 4 hoses and one drain portal. I removed drain stem 4" long and compress bottom of portal with finger and condensation started pouring out. A total of 2 quarts of clear liquid condensation came pouring out. Tested ac afterwards and drain portal is flowing freely underneath vehicle.

Testimonial: "did the same thing before I got your fix...that was it. drain was clogged..thanks!"

Could just be coming in from the wire harness if this is only happening after a rain, seal all openings leading into the firewall
