How can I tell if I have air conditioning?

[Jamesie]

I have a 1995 C180 W202. The "heater" switch goes from 1-5 with no indication that any of the settings relate to air conditioning. In any event, I suspect the AC would not have been recharged since the car was manufactured.

Getting a squeal when I start the engine which suggests to me I need to replace the poly v belt, but the size of this is dependant on whether I have AC or not. The pulleys which are in my owner's manual do not reflect what I see in the engine!

I know this sounds like a totally ridiculous question, but what's the easiest way for me to check whether I have AC?

If it has aircon there will be a button labelled either "AC" or "EC" which allows the compressor to be turned on/off (better fuel economy with it off).

No button of that kind at all, so I'm thinking no aircon! Thanks for clearing that up!

Assuming i have the right engine pic, item 13 is the pump.

Deffo no aircon, thats the basic very early W202 controls.

Here are the same controls with Aircon - note there are 4 buttons where as you have 1 long recirculate button and 2 'fake' buttons:

And here is the early climate control:
