Manufacturers took condensation into account when they designed your AC system.
The water you see is supposed to exit the system through a drain tube usually located about half way up the passengers side firewall and hangs down, it is the source of the little puddle of water you sometimes see under your car after the AC has been on.
When the tube becomes plugged the water from condensation will accumulate until it overflows into the passenger compartment.
To remedy this slide a piece of wire up the tube until the blockage is gone and water flows down the wire, you can do the same with some compressed air.
this could be from the heater core. When the heater core goes out it leaks....right into the passenger side floor board If it is water, not coolant, the problem could be a plugged air conditioner drain. Easily accesible from under the hood.
The compressor could be bad.
needs oil..
it could be the window
yes
Your heater core is leaking engine coolant into the car. You will need to replace it to correct this issue which can be a bit of a chore so make sure you are up to it mechanically before attempting. But your air conditioner is not the problem. Good luck
System could have a humidistat installed...
it could use to much shampoo and conditioner
It is important to keep the air conditioner clean and know how to remove mold as it can reduce the efficiency of the air conditioner and also cause a foul smell . You should clean the condenser and the indoor unit.
I am assuming that you have your RV's AC Thermostat set to Automatic. If the thermostat is not properly functioning it could cause the Air Conditioner to cycle on and off. Also a bad Control Board in the air conditioner unit itself can also cause the symptoms that you are experiencing. Both of the items mentioned above would have to be checked out by a Certified RV Technician in order to determine what needs to be replaced or repaired.
A very probable cause could be a bad condenser.
drain for the air conditioner heater case could be stopped up,or a heater core leaking... !!!!
