Water leak on floor front passenger side when air is on 2001 dodg

May be air conditioner stopped up running in grooves on front passenger side to back floor board

Hood misalignment, cowl cover misalignment, wiper module drain tube(s), and/or the lower plenum drain hose may cause the HVAC housing to leak water onto the passenger side floor. Diagnoses will be required to confirm the location of a water leak in the front passenger area.

It is likely that there are leaves or simular which have blocked the drain holes, however gaining access to these areas can be quite tricky and is best performed by someone with the right experience\tools

The drain tube on fire wall plugged up find it blow air in it in small bursts the debris should come out

You need to clear the water drain for the blower motor housing, and replace the blower motor is my guess here. Remove the blower motor and check the bottom of the housing it sits inside, there is a hole there, it will be blocked with leaves or other detritus like mouse nests. Use a coat hangar or any thick wire to clear it. Once clean the water problem will go away. As far as the blower goes next time it won';t work hot the end of it with a pieces of wood and see if it starts, if it does then the blower motor is defective. The blower motor is under the dash on the passenger side,.

That would be a bad heater core. You will see water leaking from the passengers side floor board. This is a complicated job to do as a do it yourself being the heater core is located behind the dash.

The rear ac evaporator box is not draining very well,and it is blowing the condensation up threw the vents,most likely.The drain should be under the rear passengers side wheel well.

Is it wet with water or coolant? If it is coolant you have a damaged heater core. If it is water it could be from a windshield with a bad seal, a leak in the floor or possibly an air conditioning system with a plugged drain tube. There is nothing else that would bring water in from the vehicle. If your are a cold climate and snow gets in on someone's boots it will melt and wait till dry weather to clear.

Good luck

This may be due to a blocked air duct, or more seriously a blockedge to the heater core if so you may notice rising engine temp. or posibly a fluid leak

There is a hose on the passenger side fire wall. You may have the water leaking back into the car, and may need an extension piece.
