As the title says,

water is leaking when I start the heater/AC under the dash on the passenger side....

any ideas to the cause?

anyone else ever get this issue?

 

The drain hose has fallen off or might have a hole look under the dash it's a black plastic box with a hose going out and aluminum ac line going in

 

Your Heater Core is bad.

 

its weird..... it was doing it before when it was raining and now that it stopped so did the pissing water when I turn the blower on. Please dont say its the rain seeping through my windshield or something. lol

It was only when the blower was on that you would here a hissing noise and water dripping on the passenger floor mat. Once the blower is closed the hissing and dripping water is gone.

..... Weird.....
