Water leak From Heater Inside Passenger Compartment

I have water leaking from the heater inside the passenger compartment. When I turn the vehicle on, water gushes out from underneath the dashboard. From researching, I assume the problem to be either the heater core or a vavle? Or could it possible be a relay problem preventing a valve from opening or closing? This vehicle also has an elcetrical problem with the interior lights coming on / off and door locks clicking with door ajar message on dash. I am trying to solve this problem also but living with it for the time being but the water problem is primary. Any help would be appreciated.

Your coolant level should be going down too, so to confirm leak at core, check that. Just in case it's water leaking in elsewhere. Can you smell the antifreeze inside? Does it do it even on dry days, no rain?
Double check hose connections are good & tight where they connect to heater core at firewall. Have seen a couple of bad connections allow coolant to leak inward to vehicle. System pressure test will confirm also.

My 2007 nissan murano leaks water on the front and back floor what do you think the problem is

Well Terry...that is hard to say with the limited information provided
so I'll give you some areas to look at...listed in order of most likely area of concern.

If your vehicle has a's drains could be plugged which may allow water to drain into the passenger compartment. To check this open the sunroof and introduce a slow stream of water to make sure the roof drains are clear and running freely.

If your vehicle has a plugged front drain pan for the windshield, that may overflow into the passenger compartment. To check this area the wipers and plastic trim parts have to be removed. The fast way is to have a helper spray the windshield with a garden hose while you monitor under the dash for leaks.

If the wet area is on the same side as the vehicles heater core
then the core may be leaking. You will smell the coolant and your windshield may fog up. Check by observing the core enclosure, while the engine is running and also check the radiator fluid level (while the engine is cold) as it will drop if the core is leaking. If the A/C drain pan is plugged (and if it is located in the passenger compartment) the collected condensation may overflow into the passenger compartment..

Good Luck, let us now if you are successful.

Water Leak

Most likely problem is a leaking heater core. This is what usually causes water leaking into the passenger compartment. Quick fix on many vehicles is to get a hose adapter the same internal diameter as the heater hoses, remove the heater hoses from the firewall connection to the heater core, and install the adapter, making a bypass loop. This will allow operation of the vehicle without coolant loss until you can replace the heater core. Of course you will have no heat in the passenger compartment during this time.

Condensate leaking from 1991 toyota camary

If you are saying you have water dripping from the heater box inside the passenger compartment, check the drain hose or tube on the outside of the firewall where it meets the passenger floor.

There is a water leak on the passenger side just in front of the firewall. It is a steady stream when I fill the radiator even when the engine is off. No water in the passenger compartment.

The heater core may be leaking or a coolant line near the firewall. The fact that the inside isn't wet doesn't mean it is not a heater core problem, as the plastic catch pan may redirect fluid to the firewall 'weep' hole.

Leaks antifreeze could it be the heater core?

That depends on whether or not you also notice some leakage into the passenger compartment footwells. If the heater core has failed, the coolant tends to fill the front footwells, particularly on the passenger side.

One thing that I have seen multiple times, though, is the water pump tends to leak, particularly if it is the original pump. They have a high pattern failure rate.

Slow leak of water under car no antifreeze in it no water inside car what can this be

It is normal for all cars that have an air conditioner. It is the condensation of the water in the passenger compartment air.

Like a house window air conditioner, the water collects on a pan and drips out a tube.

Water leaking passenger side firewall

This sure sounds like the AC condensate drain is plugged, if it is allot of condensation water builds up in the heater/AC case and leaks in on the passenger side, the drain is located on the pass side under the hood down low on the firewall, it is most cases it is a rubber nipple about 1/2 inch in diameter sticking out of the firewall with a little flapper valve in it, stick your finger in it or a stick and see if water drains out.
