What you describe is a leaking heater core,which will leak fluid into the passenger side floorboard,the "sweet smell is antifreeze,if you have in the radiator at this time.if you have the defroster on,the windsheild will fog with a sticky substance,left over steam from the cooling system leaking into the cars interior. the only way to repair this issue is to have your heater core replaced. it's a job! under the dash,behind the glove box, and the external hoses to the heater core are under the hood at the passengers side,just under the windsheild,but what we call the firewall. you will see 2 black hoses protruding through the {firewall,or dash from outside) those hoses will need to be removed,as well, as along with 35 screws under the dash to replace the bad heater core. suggest you call around for prices.the heater core itself ranges in price from 35.00 to 65.00 but the labor is the bang! research local garages for prices,but you have until cold weather to replace it,only because the heater core supplys heat to the inside of your vehicle. good luck,and i really mean research now,because most garages are not dealing with such issues now,due to warm weather.thank you for choosing fixya.com!

Tips for operating Air conditioning system on Toyota Hilux and someother...


To cool off your Toyota after it has been parked in the hot sun, drive with the windows open for a few minutes. This vents the hot air, allowing the air conditioning to cool the interior more quickly.

Make sure the air intake grilles in front of the windshield are not blocked (by leaves or snow, for example).

On humid, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

Keep the area under the front seats clear to allow air to circulate throughout the vehicle.

On cold days, set the fan speed to high for a minute to help clear the intake ducts of snow or moisture. This can reduce the amount of fogging on the windows.

When driving on dusty roads, close all windows. If dust thrown up b the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the in intake be set to FRESH and the fan speed to any setting except "OFF".

If following another vehicle on a dusty road, or driving in windy and dusty conditions, it is recommended that the air intake be temporarily set to RECIRCULATE, which will close off the outside passage and prevent outside air and dust from entering the vehicle interior.

HEATING

For best results, set controls to;
Fan speed ---- Any setting except "OFF"
Temperature----Towards WARM (red zone)
Air intake ---- FRESH (outside air)
Air flow ---- FLOOR
Air conditioning ---- OFF

For quick heating, select recirculated air for a few minutes. To keep the windows from fogging, select fresh after the vehicle has been warmed.

Press the "A/C" button on for dehumidified heating.

Choose floor/windshield air flow to heat the voltage interior while defrosting or defogging the windshield.

AIR CONDITIONING

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

For quick cooling, move the air intake selector to recirculate for a few minutes.

VENTILATION

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

DEFOGGING

The inside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone) to heat; COLD (blue zone) to cool
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- ON

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

On humid days, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

DEFROSTING

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

To heat the vehicle interior while defrosting the windshield, choose floor/windshield air flow.

I have a 2004 Dodge Dakota inside widows fog up no leak in passenger side floor board but defroster clears the windshield in the center so you can drive and all windows will fog


It does sound as though you have a coolant leak causing the fogging. Do you get a sweet smell from the heater vents? That's a dead giveaway. Often the coolant does not get to the floorboard if the leak makes it to the A/C condensate pan. Then it just goes to the ground thru the firewall. Watch for loss of coolant in the system. If you have an appreciable loss, then you should look at the heater core as the most likely cause.

Windows fog up


There is too much moisture inside the cabin. Either something is leaking water into the car, or your fresh air setting is not working on the hvac system. You can not run the system on recirculate and get rid of the moisture.

How do i clean the windshield it is kind of fog


Check your coolant level, if its low it may indicate a heater core leak into the vehicle interior. It will severely fog up the windshield and seem like an oily deposit on the glass. If good just keep the heater on defrost to the windshield or blend to defrost and heater.

Heater immediately fogs all windows and there is a sweet odor in the cab of 2003 Buick Rendezvous, defroster works fine, but will not clear the windows after heat is put on


Sounds like a possible heater core failure(hole in it) the smell indicates to me the coolant(anti-freeze) is leaking into the passenger compartment.
Check the carpet in front of the front passenger seat for moisture, this would confirm heater core leak.
Good luck !

97 LeSabre putting out a lot of heat


If it's like a sticky film, on the inside of the windsheild, and has a similar smell to antifreeze in the vehicle, then it's a heater core leak, which I suspect it is, seeing how your coolant level is going down.
