Cabin smells when heat or defroster is on

When I turn on the heater or defrost and do not use the internal air recirculation, the cabin smells of fuel/exhaust/engine. What is causing it? Any filters etc. I should replace?

    I have the same problem - Only happens when the Recirculated Air button is ON and the A/C is running. Does not smell like Antifreeze... Where does the A/C get the recirculated air from in the van? Does it pull interior air from the rear near the hatch or from the front at the dash??

What your smelling is most likely coolant (antifreeze). You may have a heater core leak. If you dont smell the same smell after running the A/C or just vented cool air from outside for a few minutes then that is your problem.

My defrost blows but is not clearing out the window seems like blowing hot air out


The Lincoln has a cabin air filter which filters outside air. It is probably plugged therefore the heater can only recirculate the the air inside the car. The results are windshield may clear but most other windows away from the heat stay fogged up.
Try changing the cabin air filter and see if it helps a great deal.

Air only blows out defrost vents VERY LITTLE


There is a cabin air filter in the unit. The filter is behind the glove box. It slides out.

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.

There is a fuel leak in the engine compartment. It could be the vapor canister for the gas tank too. The defrost and heat pull air into the cabin from the engine compartment if you don't select "recirculate".

When I run defrost, there is a bad moldy smell. Only happens on defrost setting. Is there a filter to change somewhere?


The condensation is not completely draining. You may want to see if it is plugged. Find the drain area in the engine compartment on the bottom of the firewall. Use an air compressor to blow air back through to clear it. I had a problem with that area which was a ford expedition design flaw. It was draining onto my O2 Sensor and damaging it. I had to make a bypass with a part form a GM truck.

I have a 2000 4.3L silverado. Heater & AC works but when defrosters are turned, on my windows fog. Why???


Check coolant level, if it's losing coolant, you may have a heater core leak. Does it smell like antifreeze in vehicle when defroster on? If by chance your ducting drain is plugged, it may just be water or condensation build up inside where core is. Antifreeze leak will also put a sticky film on inside of windshield, so if you wipe it with finger and it feels sticky, it may be a core leak. Be sure to double check heater hose connections in to firewall/heater core, just to be sure your leak isn't a bad hose connection before going to far if core appears to be leaking. A pressure test on system may give you a better idea what's going on. If all checks out and no leak apparent, be sure your AC compressor is engaging when in defrost mode, as that is what helps remove the moisture in the air during defrost. If compressor is not engaging, it will take much longer to remove moisture in the cabin.

Will not defrost , interior is humid(has heat), but when car shuts off interior windows freeze and must scrap ice off inside glass to see. problem is accumulative....more we drive the worse it gets


Could a symptom of 3 or more problems: (1) Sounds like you have got the cabin air intake set to "recirculate" air from within the cabin. Once the car is warmed up in cold weather you need to move the cabin air intake control so that it draws air in from outside the vehicle. Having the air intake set to "recirculate" with the windows closed means that the occupants' breath causes the windows to mist up - this gets worse the longer the car is driven, and this is exactly the problem you're experiencing. (2) If, however, the air intake is actually set correctly, then the air vents would appear to be blocked, either with debris such as leaves, or snow or ice (this would have the same effect as having the heating controls set to recirculate cabin air. (3) There is a possibility that the cabin air filter (if one is fitted) is blocked - replacement or removal should solve the problem.

According to the shop manual you do not have one.
Air Distribution and Filtering adobe.gif Printable View (79 KB) NOTE: The air distribution system of this vehicle cannot be equipped with a cabin air filter.
There are 2 sources of air available to the air distribution system:
  • Outside air
  • Recirculated air
Recirculated air is automatically used when the electronic manual temperature control mode selector is set in the MAX A/C or OFF modes and can be selected in any mode other than MAX A/C, OFF or DEFROST by selecting the RECIRC button. Recirculated air is available in all modes except DEFROST. If the vehicle is equipped with an electronic automatic temperature control (EATC) system, recirculated air is used in OFF and is available in all modes except DEFROST. RECIRC mode is a timed function in FLOOR and FLOOR/DEFROST.
Air distribution within the vehicle is determined by the electronic manual temperature control (EMTC) function selector switch position, or is controlled by the EATC system in the AUTOMATIC mode. The air distribution mode on EATC vehicles may be overridden by the driver if desired. Air distribution doors are used to direct airflow within the heater core and evaporator core housing and the plenum chamber. An electronic mode door actuator is used to position these air distribution doors. One air inlet mode door is used to switch between FRESH or RECIRC air inlet. An electric actuator is used to position the air inlet mode door.
Air enters the passenger compartment from the:
  • instrument panel A/C registers.
  • heater outlet floor ducts.
  • windshield defroster duct.
  • side window demisters.
  • center flow-through console (if equipped).
Passenger compartment air is exhausted from the vehicle through open windows or body air vents.

Try checking the cabin air filter, if equiped. It may be clogged making it draw more cold fresh air. Check your owner's manual to see if you have one or not, and it's location.
