Default ive notice if i keep the defroster off theres no water leaks

today and yesterday it has been raining and ive notice the the passenger side and passeneger rear isn't flooded like it was before when it was raining, its pretty much dry which i was surprised. the only thing ive notice is that i havent used the ac or the defroster at all for those few days when it was raining, it was kept off. would using the ac or the defroster cause my carpet to get wet? if so what would cause this?

I'm a little confused. Has the carpet ever gotten wet when it has rained in the past??? I would seriously doubt that the ac/defrost is the source of your leak. BUT, there is a drain hose from the ac/heater that directls water to the outside of your car. It'* possible that it is either clogged or disconnected. What is the history of your water woes??? Have you ever just used a hose to try and locate the leak?

yes in the past the car has leaked before when it rains, the passenger front and rear gets flooded all the time, i did hose the car down with car and i didn;t see any leaks from the door seals, iam guess it may be the drain tubes from the ac/heater??, where exactly are the ac/heater drain tubes at? i tried locting them on the passenger side under the kick panel and i cant seem to find it, the water always gets wet in the passenger middle and rear of the carpet but the driverside is always dry no water at all also by the door seals its dry, finding this leak is so hard grrrr

the AC evaporator drain is clogged-fairly common
on the firewall on the pass side you will see a rubber "dicky" that points down sometimes it'* easier to see and reach from under the car squeze it and it will unclog if you can fish a coathanger into it to draw out the debris if you just use compressed air and blow through it you will push all the water into the car and the debris which will just clog it again....eventually
hope this helps you, i have seen this problem allot (my 92 chrysler even!)
