Hello everyone,

I have a friend with a 02 Grand Cherokee Limited, 4.7 V* with an anti freeze smell in the interior compartment. Also the windows fog or don't unfog for a long time, he also tells me that after a while the vents will blow cool air. He had the heater core replaced about a year ago and it was fine until recently. Anyone have any ideas? Needs another heater core? he says the anti freeze doesn't go down and can't find any leaks anywhere. Thanks for your help!

My first thought is that it's the heater core and repair that was done.
