my heater acts weird

just recently my heater has been acting kinda weird. when i turn it on, i can hear a water leakage sound. sounds almost like turning on a faucet and hearing the water go down the drain. i can faintly hear that sound in the lower front passenger floor area. i pulled the floor mat back and there was a small amount of water that found it’s way into my car. i don’t know if i’m giving all of you a good description of this or not. but i hope someone out there knows what i’m talking about. i can’t stand it !

thanks for any responses.

Not quite sure if this is what you are talking about, but mine makes an odd sound occasionally. It is when leaves or something gets sucked into the system. I just turn it on full blast and switch around from floor to vent to defrost and it usually stops.
