My 2000 ford crown Victoria. Have water on the rear passenger side floor. What could be the problem

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)

If the smell is coming thru the vents, it could be the heater core.
The carpet on the passenger side may get wet at some point in time.

Ac condensation could be building up and dripping in cab.If so under car on passenger side were floor board meets firewall should be a small hose or maybe even just a hole where water to drip. First i use like a coat hanger to clean out.

Should be in the relay box on the passenger side in front of the strut tower.

Usually if the drain tube for the AC is plugged the front passenger floor gets wet, not the rear.

under driver side of dash.there may possibly be one under hood in fuse panel.why are looking for the fuel pump fuse???also there should be a fuel pump kill switch on passenger side floor kick pannel to the right of passengers foot behind plastic or in trunk..hope this done you some good....

Rear of engine, passenger side, right above the oil pan.

bleed them plus you have to chang eboth sides

hello lipounds , the temp sensor located on the passenger side front of engine near the #1 injector . hope that fix ya .

check the plug in the trunk lid mine did that and the plug was completely disconnected, yours may just be loose, or have a broken wire
