Foggy windows,smell antifreeze but still have heat?!?!

Started a few days ago...windows fogging up very badly and began to notice an odor of antifreeze. Defroster is doing noting to clear up the windows and there is airflow comming from defroster and all vents. This usually means heater core is shot from what I've heard. I still have HOT heat and there is no antifreeze on the floor boards/carpet, dropped the glove box today and did not locate any antifreeze in that area. ANY suggestions would be greatly appreciated. Getting very hard to drive due to the fact that this happens 5 minutes after the jeep is started

Definitely sounds like a heater core.

Definitely sounds like your heater core is getting ready to take a dump on you.

Yes, heater core. The key words here "getting ready". Even a very small leak will produce a smell. One small enough to cause fogging and smell but not yet large enough to dump the engine coolant inside.

I always like to take the "if it was mine" approach. So, I would double check all the hoses and components of the cooling system under the hood. When they check out I would then do an "old school" trick. Remove the inlet and outlet hoses and make up a temporary bypass loop. Give it some time and see if the smell dissipates and the fogging gets better. If so, then order a heater core and start taking things apart behind the dash to figure out what is leaking. Leave the heater core in it's packaging just in case it is a bad line or something so you can return it.
