In my 2004 chrysler crossfire, whats the black hose for under passenger floorboard?

Question edited for clarity.
Question moved from Computers to model category.

You soldered what 3 pins? If you are trying to bypass something, you are trying to fool two computers and it can't be done.

When you disconnect the battery, you have to reprogram the alarm and anti theft immobilizer.

Feel the water and smell it. If it smells sweet and fells oily, is is coolant. If is isn't oily and has no real smell, it is water. There is a tray under the evaporator and heater cores that catches water/coolant and drains it via a tube thru the firewall to the outside of the car. This tube is probably clogged and needs purged. If you have coolant on the floor, you'll need to replace the heater core. If it is water, purging the hose will solve the problem as the water is just condensation from the AC coils

Your drain hose is clogged. If you park under trees, debris can get in there. Once the hose is clogged, the water has to go somewhere, so it goes onto the passenger-side floorboard because that's where the evaporator is (under/behind the glove box).

Sit some1 in the car, use a hose over windscreen area, locate where the leak is coming from. Poss blocked gutters/drain off pipes that run from roof to arches. Check where the wiper motor sits aswell

It is most likely the Heater core leaking. A hose or clamps are loose or a tube is split.

is it only when the ac is on? there is a pan under the ac unit that has a hole in it to allow the condensation to empty. if that hole gets plugged it could cause the condensation to build up and back into the inside of that car. i unplugged mine and floor stayed dry

Look underneath behind the passenger side front wheel. You might need to remove the plastic mud guard. It would be easier to see if you jacked it up and put it on jack stands.

Easiest way to find it is to look under the hood on the firewall on the passenger side of the car near the bottom,The hose just comes out and aims straight down.

sounds like the drain hose for the a/c system is clogged, look underneath the car on the passenger side for a small black hose about 3/8 in make sure it is not clogged gently push a stiff wire into the hose water should come pouring out, hope this helps if not get back to mme as i strive to be the best, please rate my fix

2004 TB 60,000 miles. i was just told that the leaking fluid in my passenger side floorboard was do to a clogged up A/c hose. An A/C works by drying/ removing the moisture from the air inside the vehicle and cooling it. The accumulated fluid is usually evacuated under the vehicle which is what you see when people are stopped at a red light and there is dripping under their car. when a hose is blocked there is a vent that from some reason flows directly into the passenger side floor board. If you can not manually knock loose the block your probably going to have to take it to a mechanic.
