Steam coming out of the dash vents - 2005 Jeep Liberty Sport

bring back to shop and advise of problem most likely improperly replaced or damaged vent doors/actuator

Does it smell like antifreeze?

the heater core is removable from the climate control unit. The climate contriol unit has to be removed to replace it. The A/C system must be evacuated and lines removed as well as the dash, to access the climate control unit. The steam is coming from a leaking heater core.

You have a leak in your heate core, located behind the dash on the passenger side. Common problem, I have the same vehicle and had the same problem. Parts not that expensive, but many hours of labor. Dash has to be removed from vehicle!

this would be a bad heater core. this is located under the dash on right side inside the heater box next to the blower motor the steam is acctualy radiator fluid that runs through it.

These are signs of the heater core leaking.The only bad news is that the dash panel has to be removed to replace the heater core.

Should be a central vaccuum block behind your selector for vent defrost etc. perhaps that is going bad. They're expensive for something made of plastic. cheaper alternative is the junk yard.

Your heater core has corroded through. You need a new heater core. You may be able to get by temporarily, with bypassing the heater core hoses, located in the engine compartment. These hoses carry coolant heated from the engine, to the heater core. You remove the hoses from the core, and put a pipe in the middle, connecting the two hoses together using hose clamps.

Should there be a cool morning, or if you need the defroster, you won't have warm air. Just a temporary fix.

You heater core is leaking causing steam to come out of the interior vents. This is quite a process to replace a heater core in one of these cars. The entire dash needs to be removed. The core itself is located under the middle of the dash towards the top. If you do this job yourself, take your time and allow a full weekend to do if you've never done one before.
