Question about Mercury Grand Marquis
Check the passenger side carpet and see if it is wet.. if so then your heater core is leaking into your car and you need to have it replaced. If you do not see any leaks there then check under your hood with a flash light and look for a green liquid and see if you find any leaks... usually check your hoses and under your water pump also check your radiator and coolant reservoir level. Good Luck Friend

This is definitely a heater core issue, but I might also suggest one of the many over the counter cures first before replacing it, the heater core is not a very expensive part but quite a chore to replace.

do you smell antifreeze? does it steam up windshield when defrosters are on? is there antifreeze on the floor. if your answer is yes to any of the questions i asked its heater core. the best thing to do is go to a web site of any major auto parts store they will have all the diagrams and instuctions you will need to do this.

No antifreeze in what? the engine, or what's leaking on the ground? if leak is water, under the vehicle on the passenger side between the front of the door and behind the front wheel, it is coming from the air conditioner drain. It is supposed to do that.
If what's on the ground is antifreeze, check the heater hoses and control valve.

Check the floor mats for moisture; you may have a bad heater core.
You can also get fumes from an under-hood leak if serious enough, check the level in your coolant overflow to make sure you aren't losing a lot of coolant.
BTW, replacing the heater core can be a real hassle; they are normally installed before the dashboard and can be nearly inaccessible.
