Your heater core, which is under the dash is supplied by coolant from the engine. If it is leaking, or the hoses to it are leaking, it could end up on your carpet. Also, if the drain for the A/C evaporator is clogged, you would have a similar result. This sometimes happens after getting a car undercoated.

"Cleaned it out"? The evaporator box or the drain hose? Sometimes algae will grow in the box and plug the drain hose. Quick way to check is to use an air hose and blow up in the hose where it comes through the firewall. If you had the box out, did you kink the hose putting it back in?

How difficult is it to identify and repair a leaky hose?

If you use water or garden hoses, then identifying a leaky hose is not difficult. All you have to do is seal the output end of the hose with a sprayer or cap and turn on the water. You will usually find the leaks as you will see water spraying out somewhere in the middle of the hose. Repairing a leaky hose is not too difficult. You can duct tape or electrical tape to seal the leaking parts of the hose. Please not that this a temporary solution and you should probably purchase a new hose if your does spring leaks.

Check the float valve, all connections, and for holes [leaks in the water reservoir].

My 81 Tbird has a hose that is coming out of the firewall into the engine area on the passanger side. Antifreeze coming out not all the time. What is this hose Hose is small in size.?

It is an engine oil coolant hose. It runs to the oil cooler, which is a dual processing unit. Oil flows through one side, and antifreezeengine coolant flows through the other.. The hose you are talking about carried antifreeze to the cooler, and then to the engine.

How do you stop your 2005 dodge neon from leaking in the front passenger floorboard when it rains?

First you have to find where the water is coming in. Have a friend use a water hose around the windshield, cowling, etc. while you check inside for leaks. Water could be coming through the firewall around gaskets as well. Be careful to not soak any electrical components if squirting water under the hood. After finding the leak then you can decide the best course of action to stop it.
