Water leaking into cabin through heat vent and firewall on passenger side. Just bought car with 88000 miles. Took it on a 600 mile trip, hot weather, AC on and no problems. Week later still very not weather and after about 20-30 minutes water starts coming out of firewall on passenger side and also through heat vents. Is a drain plugged or something else

Make sure it is just water and not coolant. Is the windshield getting a slight filmy build up on it when defrost/vents are on? Could be bad heater core.

Don't think it is coolent. Got under car and found drain hole. Poked a screw driver up into it and water came out so hoping it was just plugged
