Air Conditioner on 1996 Mercedes-Benz S320

Hello all,

I am having a problem with my AC . I turn on the AC and some air comes out but not much. Also, I smell a sweat antifreeze like substance coming from the vents. I happens when I put on the heat too.

Thank you in advance,

Hey David,
Sounds like you may have two issues here. The smell is likely from a leaking heater core, and the air flow could be from a plugged cabin air filter, but possibly something else.
I would have a Mercedes shop look into these issues for you. Here are some near you:
