Sweet-Burning Smell when vent is on

When my car heats up, sometimes (and only when the heat or "vent" is turned on,) There is a sweet smell that blows through the vent, however if it runs long enough, it will develop into a burning smell. Any ideas on what it could be??

I am quite certain you have a leak in the heater core and you are smelling the leaking antifreeze. Check the coolant level for loss and look under the car where the water from the airconditioner normally drips.
Hope this helps you, Robert

Smells like something is burning when turning on fan mostly when turning on heat. Also makes a gurgling noise. Can hear it and smell from interior of van


Check you coolant level(gurgling sound). A sweet smell is most likely a leaking heater core. Burning oil is valve cover gaskets.

When i start white smokes comes out why


mine does the same thing.. it is a sign that you are burning oil kiddo..either that or antifreeze is finding its way into the engine through a crack or bad gasket.. check for oil smell and moist soot at the tailpipe, or a sweet smell if antifreeze..now if its a steam like smoke..thats normal byproduct of the burning fuel and goes away once the exhaust pipes and muffler heat up enough to blow out all the condensate water...

I have a 2002 hundai accent , drove car approx 15miles with radiator steaming to shop. replaced radiator. now needs o2 heat sensor and I!m smelling a sweet type coolant smell, but very little and its...


the sweet smell is the motor burning off the residual coolant on the components that got sprayed with coolant.if the car got overheated enough it may have damaged the head gasket and is now burning oil due to the over heating.or there is a mechanical problem due to the overheating(ring problem,valve problem,etc.)if its burning oil then it can cause an 02 problem as the sensor will get coated with what ever is coming out of the exhaust.the heat sensor is part of the 02 sensor that warms the sensor up so the computer will go into closed loop sooner and help with fuel mileage.

There is white smoke coming out the tailpipe no smell of antifreeze


If it doesn't smell like sweet then you most likely got a bad tank of gas. Just to be safe keep an eye on your engine temp. and coolant levels.

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 !

Heat gauge shows hot , have to add antifreeze although no leak


Very common fault is head gaskets.  causing coolant consumption and bubbles in radiator.  Run vehicle, have a friend accelerate once or twice hard, while you smell exhaust for sweet smell of burning coolant.
