Wet drivers side front floor and rear right floor

I have had the heater core replaced because it was leaking on the passenger side front floor. The other 2 areas are still getting wet, it is not caused by the rain is happening when I drive the car even in dry weather. It gets wetter if I have the defrost or heater on.

It's probably a blocked a/c drain line. The condensation can't drain out because the hose is blocked w/ 'goop', U should be able to locate the drain hose in the passenger area, front seat about where your feet would be, middle of pass area. U can either blow air thru it to clear it, or from under the car, locate the end of the hose and with a small wire, gently run it up the hose to clear obstruction. The carpet padding is like a sponge, so the moisture is probably wicking to the rear area from underneath.
Newer cars run in the a/c mode whenever heat or defrost is on, even though u don't turn on the a/c. Let me know how u make out.

Have a 94 Buick century. Replaced thermostate. Running hot. Looks as tho is leaking underneath front near pump. And also in passenger floor board can't see the leak from inside. It's just alwa


Whenever I see a system which is leaking from more than one or two places, I do a head gasket check because that tells me that the system is experiencing above normal pressures. the wet floor is a heater core. whether it's a water pump or some other thing near it only you can tell. Actually it rarely happens, but the wet floor could be the hose where it meets the heater core at the firewall; again, only you will be able to tell the difference. if the hose connection looks dry, assume that it is the core itself.

WET CARPET ON DRIVER'S SIDE


Could be the drain for the ac is plugged up. Usually when this happens the passenger side floor gets wet, but it could be coming out on the driver's side when you take a right turn.
The drain should be on the bottom of the firewall near the floor, you should see water dripping onto the ground when the ac is on.

Question:Are you running your heater? If yes, your heater core is leaking. Its located behind the dash on the passenger side. Sorry to say, change it. You can do this yourself. Just a tight space to work, and hard on your patience.

Check to see if the passenger front seat carpet is wet by the engine fire wall. use a paper towel or tisue toulch the carpet. If it is the heater core could have a leak and must be repaired or replaced.

Passenger side floor board is wet.


Hi Big,

Heater core is on the passenger side under the dash.

Are your coolant levels low?

Start your engine and set the heater on high. This allows circulation through the core. Now check for leaks. Place a paper towel or two on the floor. This will allow you to see the color of whatever is leaking. (e.g. antifreeze)

Fogging will only occur when there is a temperature differential of more than one or two degrees between the inside and outside of the vehicle.

Best regards,
Mike

Wet rear floor


Have you by any chance jacked up the passenger side, or got vehicle on a hoist to make sure there isn't any plugs on the underside that may have fell out? They could be round or oval metal or rubber plugs, probably in that area.
