E240 AC on/off issue

Hello all,

I am new to the group and I am not sure if this issue has been discussed in the past. I appreciate your help.

The AC off button on my E240 is on all of a sudden. When I try to switch it off, it blinks then stays on. As a result, the air is not cooling.

I will be trying the following:
1. Check the fuses.
2. Check if gas re fill is needed.

Before doing the above, can you please advise how to reset the AC/cooling system on the E240 (hopefully it will solve the problem).

Also, can you think of other things I should try apart from the above mentioned?

Thanks,
Reply

Well, I read somewhere in this forum that a reset (for another Merc model/C Class) is performed by pressing and holding the "Defrost" and "Recirc" buttons together.
