What can i do when my2001 L seriers got some kind of liquid think its water all in floor board

heater core is gone. Under passenger side of dash

There is a drain coming out of the Heater & A.C. box it should go thru fire wall usally on passenger side.What kind of car?

your ac drain is blocked

it may not be rain water ..if its in the right front floor board ..check for leaks in and around the heater core or the hoses that supply the the heater core with water [coolant] ..also keep a close eye on the amount of water [coolant] that is in your radiator..if its coming up low each time you have checked it ..its almost a sure bet that is where your water [coolant ] is being lost..or going [into your floor board] so your thinking it rainwater..

Heater core is bad.

Look for dislodged AC drain hose, at the base of the heater box area. These get kicked off by accident, by feet.
this hose is typically abotu 1/2 in diameter, and only jamb fitted.


This is presuming you do not think it is rain or coolant causing liquid.

check your water pump see if it is leaking or not

Sounds maybe your engine is burning it and the flow in the heater core is less then normal capacity , you can hear a liquid "swushing" noise, making sure there is no water under floor rug/mats. A foggy smokey exhaust would be notice.Miata has an aluminum cylinder head and cast engine block, usually head gaskets leak into the cylinders. good luck

If it is antifreeze, yes. It could be just water from a clogged a/c drain or rainwater leaking in from a bad seal.

Probably condensation from the air conditioning. No sweat.
