Good evening all.
I am trying to figure out my dash controls and have a few questions for you that know more than I do.
In my center console are my climate control switches and I know most of their uses, however there are two that I have not been able to figure out. I do not have an owners manual for this car, and everything I find, including the cd that comes with the car, shows a different setup with push buttons. The middle two buttons as shown in the picture is what I am asking about. I believe that the bottom switch is for use outer air or using the air inside the cabin of the car. The upper switch is for A/C and heat? This switch feels like it has three positions, one for the A/C one for the heat, and a center position that I am not sure of. On a cooler day I had the switch in the middle and I felt cooler air coming from the vents, yet I had heat coming from the defrost vents.
Could someone advise me on the use of all the switches?

The one between the dial controls is recirculating switch that close outside air. You push it when you drive close to the beef farm . It is timed and will go off on its own in few minutes.
Not sure about upper center one, but looks like windshield quick defroster. That switch is activating both -heat and AC for quick defrost and drying.

Agreeing with Kajtek1 on both counts. The lower icon on the upper switch looks like a windshield so in that position it should be the defrost. I have 2 similar to that but slightly different shapes. One is for the windshield defrost w/fan and the other activates the rear window defrost wires. The bottom one is clearly the air recirculate feature.

A 1981 380SE is a W126 and you might post this photo there too. Those guys are the experts on your chassis. Just scroll down the home page (this is the general forum) and look for the sedans section and you will see that.
