Sounds like heater core is leaking
you probably need a new thermostat, remove the one you have then get a new one asap.
Water in the passenger side of the dashboard means the evaporator core is leaking. This needs to fix quickly as it will cause the inside of the car to be filled with water.
If it is water it is probably the condensation drain plugged up with crud. If it is engine coolant it is probably the heater core leaking.
your windshield seal has failed
because the air condition is cooling the air! The colder air gets, the less water it can keep. So the water drips out of the box, where the air is cooled.
Sounds like either the windshield seal if defective or the heater core is leaking Check to see if water? is antifreeze
bypass the heater core by connecting the two heater hoses togethetr or replace heater core
The pipe that runs under the back rear of the passenger side of a 196 Pontiac Grand Am is the water pump. If there is leaking under the passenger side, the first thing to check is the water pump.
Your Heater Core Sounds Like. heater core Another answer== Water from condensation when using the AC, or coolant from the engine cooling system. Test to tell: if it smells like antifreeze, the heater core is leaking. No smell or just smells wet, it it condensate and a drain line is plugged or blocked causing the water to back up into the passenger compartment.
Probably on the passenger side, under the glove box. The heater core is leaking, you should probalbly smell something sweet with the car running. That's the anti freeze.
If you have your air conditioning running it is the moisture that is pulled out of the air when it is being cooled. That water is then expelled outside of the car
have your heater core checked its probually leaking
It's the coolant control valve for the heater core that's leaking. It's under more pressure when the engine is running and that why the leak is more noticable.
This is either the heater core leaking coolant or the air conditioning drain line is plugged. If the water tastes sweet on your tongue or is warm it is from the heater core.
either ac drain is clogged or heater core is leaking
There is a drain on the outside firewall that is clogged.
more than likely the heater core is leaking
AC condensation drain.
you could have a heater core leaking or your windshield is leaking and the water is running down behind the dash and onto the floor.
If that water is engine coolant, the heater core is leaking.
Water pan is not something that I am familiar with, but if you are getting water on the floor on the passenger side then your heater core may be leaking, the drain tube for the ac is blocked ( it sticks out through the firewall on the passenger side and can be cleaned out with a coat hanger or compressed air).
The condensor drain line is stopped up. Clean out this line.
It can be one of 3 things. My first guess would be a leaking heater core considering the area where it is leaking. Are you sure this is water and not coolant. If it tastes sweet or is slick to the touch, it is coolant and you have a leaking heater core that must be replaced. Secondly it can be the windshield seal that is leaking. And 3rd it may be that the drain holes below the windshield cowl are stopped up allowing water to enter the passenger compartment.
Your heater coil is most likely leaking. The heater coil is on the passenger side of the car just behind the dashboard/glove compartment. If it has a bad enough leak, the water could go all the way back to the back seat area. Check the coolant level in your car as soon as possible or you might damage the engine.
