I have noticed white smoke coming from the vents while driving. I am not overheating and no moisture on the floor of the passenger side. Smells like antifreeze, Otherwise it runs fine, My dad takes great care of my Jeep and I would like to research this before bringing this to his attention, Thank you in advance for your input !

The smell of antifreeze is your heatercore leaking. Give it some time, and you should beable to feel the leaking antifreeze on the floor. Its in its early stages, but will only get worse. I suggest you replace your ac evaporator core while doing the heater core. Its a couple hundred extra, but well worth it.

Dont think its over, a heater core that leaks externally will continue to leak. The flush may have found a bit of sludge to clog the leak for now, but I believe the leak will come back. Keep a very close eye on it. Once the temp starts going down in the enviroment, towards winter, you may experience windows fogging up. I dont want to bring you bad news, but I have seen this time and time again in the shop. Keep me updated.
