Air conditioneer blowing hot air with no leaking fluid and sounds like water is running in dashboard on passengers side

SOURCE: Changed batteries and climate control not working properly

The actuator has gone bad. They can be programed, and reset, but usaly they are bad, and that will only patch the problem for a while.

I have had this problem. I am not a mechanic...so to correct the issue temporarily, I simply turn off the car and restart. This has worked everytime for me. In extreme cases, I think you can also remove the AC fuse and start the car, which will also reset the computer. I also think that by taking the climate control off the "AUTO" setting has worked in the past.
