Default Steam from defrost and air vents

The car reaks of antifreeze. Cant find anything leaking inside cab and this readiator and reseviour were a tad low. But this light foggy-ish (is that a work) steam comes out of the defrost vent under windshield and from the ac and heater vents. Is this a easy fix or what? I just changed the entire clutch assembly this summer so I really dont want to work on this damn thing again. 160,000 miles and still running strong till now. Any help would be great. Thanks.

Heater core.

Nothing sounds easy to me about coolant coming out of your A/C vents

Yeah, definitely heater core. You probably have a restricted core and a pin hole leak where the steam is coming from.

If it gets really bad, you will have a wet foot well on the passenger side under the dash.

You're not going to want to hear this then... you're going to have to remove the entire dashto replace the heater core. If you live in a warm climate, you can bypass it at the firewall. But if you're like me and watching it snow right now, then you're gonna want to replace it.

Bypass it and trade it in.

Had to replace the core in my 2005 Blazer this summer and these are the instructions that I followed. Found the instructions on the Internet ......
