Your heater core needs to be replaced. The heater core is like a mini radiator, providing heat for the interior by coolant circulating from the engine, into the heater core, and back to the engine again. Like a radiator, a heater core can spring a leak, especially w/ age as a factor. This results in the leak inside the car, which also causes the 'smoke' you see, which is actually vapor form of coolant.

Floorboard wet on drivers side on my 1995 buick skylark

There are a few things you will need to check as the leak could be from windsheild or floor. the first thing is to vacuum floor next is to use a water hose and spray all over windsheild while someone is looking with light inside under the dash to see if water is coming inside, if so then window resealing is needed and window has to be removed. next is to look at floor board from under the car for rust hole, this is the way to go. let me knomw the out come. good day

I have an 1999 chrysler 300m an it has an overheating problem. There is also water all over the driver side floor (front n back) it is soaked. It takes about 25mins b4 it starts smoking. Can som1 plz help...

Typically if your leaking coolant inside the car, it indicates your heater core is split and leaking. Replacing the heater core is quite the job. It requires removal of the dash board and heater box. i replaced one in a 97 Cirrus at work last week and it was a 6 hour job. If your not mechanically inclined i would definitley recomend phoneing around for quotes to local auto repair shops and getting it done profesionally.

I was driving a 1997 Buick Skylark Custom 3.1 less than 5K when white antifreeze smoke started filling inside the cabin of my car. It appeared to be coming from inside the dashboard and the windows were...

The "smoke" you saw was your coolant. The vehicle uses engine coolant piped into the cabin of the car and through a little radiator under the dash for the heater. The blower in your car forces air over this radiator and this heated air is what you feel at the vents.
If you're lucky then one of the hoses has sprung a leak. This is a relatively uncomplicated cheap fix. The other thing that could have happened is that the cabinheater radiator has sprung a leak. If the leak is serious then the heater radiator will need to come out for repair or replacement.
You could try running some radiator stop leak(I've used Wynn's before) through the system and see if it helps. If the leak is on the radiator it might just work. On the pipes it will not be successful. Buy a bottle at your local spare shop/Autozone. Put it in the cooling system(do not open a cooling system with the vehicle hot!) and let the vehicle idle for a while. (Read instructions on the bottle) If it does not work, have the heater radiator removed and repaired.

Heat is not getting hot Installed a new Thermostat but that was not the problem.What could it be?

Heater core - located underneath your dash board on the passengers side. 'can be a major pain to replace it'.
Possibly a radiator issue also. Are you finding any leaks from the car on the floor of green fluid/antifreeze?

Wet under driver's side floor mat

Is there a sweet smell inside the car?Heater core leak I beleive would be on passenger side floor.Antifreeze will be sweet to the nose.Are you getting any white smoke out the tailpipe? would likely be head gasket leak.Put a piece of cardboard under the car near the radiator and under the motor to see where its leaking from .One thing Ive learned over the years is that its going somewhere.On the ground? Or out the tailpipe.
As for the floor board leak the 98 s were prone to have the defrost area in front of windshield collect water from being plugged up .Mine was passenger floorboard.Daughter resealed small oval vent (that defrosts /heats hood?) LOL .Its on pass. side under hood on cowl .I think this will take care of my problem but you may need to investigate under the dash/defrost area and drill and then install a drain line to bottom of defroster.Exit drain line to O/Side of .Also was it raining ? was car outside in rain .if so it could be this issue.Sorry so long ,hope you can make heads or tails of this.
