Yeah when i turn on the air/heat i smell anti freeze. theres no apparent leaks and it isnt losing coolant. What is going on? i smell it most when the heat is on.

My bet is your heater core, which always has hot coolant running through it, is leaking. It is located up above the passenger side footwell.

Best and easiest thing is to have your system pressure tested but the smell usually indicates a leak in the heater core. On my son's TJ I went over to Home depot and made up an adapter with 2 hose barb fittings and bypassed the core till it was fixed. The hoses are 2 different internal diameters but with the hose clamps I was able to make it tight.
Rockauto.com has cores. this part is simple. Replacing the bitch is another story. Get a FSM- No! not Clintons or Haydens. Its not difficult, just a ROYAL PITA
My bet is the heater core as well.
A new one isn't spendy, see here:

However, it's a pain in the butt to do.
Here's a good write-up on how to do it thanks to @JFjeld:

Oh boy. This jeep is starting to remind me of the geo tracker. Well thanks for all the replies. I will see what i can do about this. stay tuned.
OMFG i just saw the directions for this project. I dont think its getting fixed. Anyways i have a jeep wrangler my gf is selling if anyones interested XD
Tell me about it. The VA will have my second hearing aid ready October 3rd.Hearing loss... It's part of aging
I assume you have a lot of tinnitus from Vietnam? I only did 4 years in the Army, but I have that ringing in my ear from time-to-time.
I did 23 years of artillery and helicopter turbine engines. Had several cortisone shots in my right shoulder. When I retired the VA denied disability! I haven't dealt with that bunch since! Still cant hear and had to have two surgeries on my shoulder.
It was the VA who the hell knows! That was also 26 years ago.
Back to smells like coolant..
Yep in addition to shitty hearing I have tinnitus too. I can "hear" but it's muffled and women's voices are significantly harder to understand due to their higher frequencies. At least lower pitched men's voices are mostly ok for me so long as I'm not also in a noisy room. I haven't been able to hear a drum cymbal in years.
Stinger, I'd go back to the VA about your issues. They've become a lot more responsive in recent years, my local VA clinic has been treating me extremely (!) well.
The vent system is probably just carrying the coolant odor out of the Jeep. I can think of no reason you should smell coolant at all in the interior except when the heater core is leaking.
