What are causes antifreeze smell in cabin?

I have a 2004 T&C LX and recently I have noticed a sweet aroma when I
first turn on the heater fan, also the windows inside get fogged up
land do not respond to the defrost setting.

Could this be a simple fluid hose leak or am I going to have to deal
with a defective heater core and all its replacement issues and
expense when taken to the dealer?

I thought I had extended added care warranty coverage for this heater
component, but a read of the coverage doesn't mention heater core
anywhere!

Thoughts and suggestions would be appreciated.

I'm guessing that the heater core is most likely, but it actually isn't
impossible for it to be anything the coolant goes through from the
radiator on back. You'll need an actual diagnosis to know.

 

I wouldn't think a leak forward of the firewall would cause the symptoms
that are described to the degree that they are, Joe. I suspect heater core.

 

ditto on the heater core. i recall the hose connections are outside in the
engine bay not inside the cabin.

just curious is it low on coolant? that might be a hint of fluid loss.

 

Many thanks to the responders for their input - yes I have noticed a
slight loss of engine coolant. From the assessment I guess I'm looking
at replacement of the heater core. I have been told that removal and
repair/replace heater core is a labor intensive undertaking - as it is
located under the dash and requires removal of the dash and other
obstructing components.

I'm hoping that antifreeze aerosol laden cabin air is not a hazard to
the respiratory system - it sure coats the cabin glass!

If, you need to us ethe vehicle and don't need the heater, then disconnect
the heater hoses from teh heater core. Simply connect the two hoses
together. This works well down south were does not get to cold but I know
you folks form the North need your heater like we need our AC.

 

yeah the entire dash has to come out i think. its that way on the mini vans
and the Cherokees too. about 6 hours i think but don't quote me on that.
