Try going to autozone or any auto supply that lends tools for free ask for their pressure tester and fittings for your cooling system. open hood make sure vehicle has not been running for at least 8 hours. open coolent tank and attach the tester. Pump it up to 13lbs or high test limit., check in and outside of the car. I beleve you will find your heater core is leeking or a heater hose has gone bad .I suspect it will be the heater core . if this was helpful please leave me good feed back.

SOURCE: Bad smell coming from heater/ smoke coming out vents

I had the same problem in my 98 Dodge Dakota! Replaced the heater core, problem solved. No more funky coolant smell and erie fog coming through my vents. I bought the heater core at rockauto.com online. Have purchased many items now from them. All factory parts so far at half the price of even AutoZone, even with the shipping. Also, you usually have to wait only a couple of days depending on the part and they have EVERYTHING.

SOURCE: antifreeze smell and smoke coming out of vents

You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.

SOURCE: Antifreeze smoke coming out heater vents

depending on how bad, and how long the orginal core leaked, it might just be residue in heater box, and if it got up into the vents, it will take awhile for it to dry out.

SOURCE: 2000 grand marquis cruise control not working

Have seen this problem before. You need to look under dash at brake pedal and find a blue switch with plunger contacting pedal, disconnect connector and jump with a peice of wire and drive to see if cruise works and if it does replace deactivation switch this should get you going.

2000 Mercury Grand Marquis only blowing through dash vents


C Craft, it could be a couple of different things but from what you stated my best guess is it's going to be a issue with the door that diverts the air to the position that your selector knob is in on the climate control on the dash. If you can turn the selector knob and actually hear the actuator moving the door but the air doesn't change vent positions, then I would say the door is broke.
Now, you also want to check and make sure that there is vacuum going to the control. The main vacuum line coming from the engine is located around the passenger side firewall under the hood. Make sure the line is not broke or come unhooked. You can pull the control head out of the dash and actually crank the engine and check to see if it's getting vacuum that way by unplugging the vacuum line assembly from the back of the control head. If your getting vacuum to everything, then it will have to be a problem with the door itself which is in the air box behind the dash and it is not a easy fix. I would suggest having a qualified mechanic look at it if what I have told you don't check out. Hope this helps you.

Why is there white smoke coming out of the air vents in my 1995 grand marquis


It is either steam from the cooling system and will have an odor, or is frost from the a/c system due to a system that is restricted and freezing up. Or you car is on fire. If it smells like smoke, run or you will die from smoke inhalation or burning to death.

I have a 1997 Mercury Grand Marquis. The hotwater


Check your antifreeze with a antifreeze checker to make sure it is at the right temp depending on where you live and how cold it gets there. If you have too much antifreeze the engine temp will not come up to over 200 and also replace your thermostat, making sure to realize they make them in different temp settings. Talk to people and make sure the thermostat you install is the right one for your climate where you live. Sounds to me as though your temp never comes up to what it should be. Also it could be the heater core.

Car failed for visable smoke 93 marquis


A temporary solution for removing oil smoke. (oil burning )
Use synthetic oil with 3 cans of STP oil treatment with oil level brought only to the add mark on the dip stick.

The synthetic oil will burn clear and the STP will reduce the oil burning to almost 0 for a day or two.

To reduce antifreeze burning.......put a rad cap on that cannot hold pressure and is vented to the overflow bottle......rip the rubber gasket on the cap in two...leave half there.
This will cause no pressure to build up in the cooling system and should reduce antifreeze burning greatly.

REMEMBER.....if you have filled the exhaust system with a burning product....antifreeze or oil.....it will take time to burn off and out of the exhaust system.

These are temporary solutions just to get you through the test.
You may need major engine work to correct a smoking engine for long term use.

Smoke coming out vents when defrost is on and temp gauge goes up and down in 1994 Taurus


The fluctuation in the temp gage indicates a low coolant situation. The smoke you see from the defroster vent is actually antifreeze that is leaking from the heater core somewhere and as the antifreeze evaporates from the heat it causes a vapor to produce. You should smell a very sweet smell when you see the vapor. If so it is definitely antifreeze. Find the leak and fix it. Then refill your coolant system to specs and you should be good to go.
