Aircon/Heating switch replacement

[blackhill]

Any advice on the part number just for the left switch rather than the whole unit?

Thanks in advance

Doubt very much thats a seperate part from MB.
best bet is find out who makes the actual unit and contact them.

Could buy a cheap used unit on ebay and transfer the switch button if you cant buy a new one. i doubt a breaker would even sell just the switch as it destroys the unit. I did this on my sons BMW. Unit was £20 (didnt matter if it worked1) expensive for a switch but sorted the problem
