Why is my Ford Mondeo making a strange noise when I turn on the AC?

Recently, whenever I turn on the AC in my Ford Mondeo, I hear a strange noise coming from the engine. It sounds like a high-pitched whining and it's quite concerning. What could be causing this noise and is it something I need to get fixed immediately?

It sounds like your AC compressor might be failing. This is a common issue in Ford Mondeos and can cause that whining noise you're hearing. I would recommend getting it checked out by a mechanic as soon as possible before it gets worse.

I had the same problem with my Ford Mondeo and it ended up being a loose belt. Do a quick visual inspection of your belts and see if any of them are worn or need tightening. That could be the simple solution to your problem.

I had a similar issue in my Ford Mondeo and it turned out to be an issue with the blower motor. I would suggest taking it to a trusted mechanic and having them take a look, just to be safe.
