All answers are correct..!!..DO NOT operate vehicle ...Wear mask and drive it straight to a Trained Tecnician...Or if you are a DIY replace Heater Core..Clean inside of vehicle..,After job is complete roll all windows down and run vehicle sitting still with heat on wide open for at least 45 minutes...Clean windshield thoroughly with Windex..,Place many fragrance Air Fresheners in vehicle and let it set for an hour at least before driving..
It is not smoke though it appears so. It is thick heavy steam from a coolant leak in your heater core in the cabin area. It will smell very sweet if it is a typical glycol based antifreeze, and the windows will fog up as the hot coolant enters the cabin area of the vehicle. Primarily on the inside of the windshield. The cure is that your going to have to replace the heater core as it is leaking. Do this soon because if it ruptures completely you will have a major mess on the floorboard of your vehicle. Coolant is also poisonous to humans and animals if ingested. The heater core will be a little pricey as will the labor to replace it. Good luck. I guarantee you it is the heater core leaking.

Yes it's the heater core, It's a complicated diy job and unless you are an experienced mechanic you are going to need a good workshop manual for the job.
Best of luck.

Have a shop pressure test the cooling system, this will make the leak easier to locate, if I have to guess I would go with a leaking water pump.

Make sure the cooling system is clean with fresh coolant when u change the core, otherwise u may damge the new core becuase your coolant is worn out, if your Jeep has over 60,000 it should be done anyway, also I recommend at least a new upper radiator hose while it is drainned and inspect the other parts of the system.

Yes you do need a heater core, if not replaced it will only get worse.

well then it sounds to me as if you need a transmission replacement...a flush or service at this point won't do you any good, as the transmission is using the contamination in the fluid to build pressure. so if you flush it all away, then the new fluid is way too thin to build any pressure...just replace your transmission....
