Why does my Vauxhall Vivaro keep stalling when I turn on the AC?

I have a 2015 Vauxhall Vivaro and every time I turn on the air conditioning, the engine stalls. This only started happening recently and I'm not sure what could be causing it. My mechanic couldn't find anything wrong with the engine or the AC system. Any advice on what could be causing this and how to fix it?

It sounds like there may be an issue with the AC compressor or the electrical system. It's best to take it to a specialized mechanic or dealer for a thorough diagnosis. They can use specialized tools and software to pinpoint the problem.

I had a similar issue with my Vauxhall Vivaro and it turned out to be a faulty AC relay. It was a simple and inexpensive fix, so I would suggest checking that first.

Make sure you don't have any aftermarket electrical accessories plugged in, such as a USB charger. I've heard that can sometimes cause issues with the AC in Vauxhall Vivaros.
