Want this question answered?
At the bottom of the firewall on the passenger side
cannot locate AC drain tube on 99 town and country. Water in drivers floor board, only when running AC.
There is a drain on the outside firewall that is clogged.
Passenger side of firewall, under the ac accumulator.
The evaporator drain allows condensation from the ac unit to drain. When the drain clogs up water will go into the passenger floor instead.
On the firewall passengers side under the hood....................
Your drain pipe, that drains the condensation water from your ac/heater core might be blocked. (Happened on my 2006). Cost me 50$ at the stealership.
If you have a plugged AC condensation drain, clear water will back up and end up on the passenger floor. If the heater core is leaking engine coolant you will have engine coolant end up on the passenger floor.
if you look it is right next to the tank that holds the blinker fluid.
If it's not related to outside weather, then check the drain for your AC condenser.
I would check your AC evaporator drain tube , if clogged water will drip on floor.
all ac systems drip water if working correctly-----if water is getting on floor of car,the drain tube is plugged
