Hi dear,

As I have two identical Mercedes Benz, I took the van and tried it in the other car, and it was working so I took the climate control switch, and it was working too. All fuses look okay but they’re still not blowing air. Waiting for a solution.
Thank you

Yep, the main power wire and connector can burn in these cars so I would look at that first. Here are the blower motor wiring diagrams so you can see how the system works and this guide can help you test for power and ground at the blower motor to help confirm the failure:

Please check fuse #30 in the fuse panel at the left side of the dash.

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Hi,

You answered my question thank you very much and it was a power fuse problem. The one on the left-hand side of the dashboard and it is now working but another problem appeared.
The new problem is when I switch the car off 20 seconds later with the key off the car. The fan starts working by itself and stays on until I switch the ignition on again.
I hope I was clear thank you very much and waiting for your solution.
