Yaris AC Not Cooling

AC not working on my 2014 Yaris diesel. It doesn't engage when I hit the AC button. I'm thinking it could be the valves controlling refrigerant flow. Anyone seen this before and have ideas on how to diagnose it before I spend a ton?

I've seen similar AC problems. Before replacing valves, which can be pricey, have you checked the basics? Is the blower motor working? And have you had the refrigerant level checked? A leak could shut the system down. Just ruling out the simple stuff first.

Thanks. The blower motor works fine. How can I check the refrigerant level without special equipment? I don't want to mess anything up or spend too much, but I want to avoid unnecessary costs.

If the blower's good, that helps. Checking refrigerant properly needs the right tools. Since you suspect the valves, you might be right, but it's AC system specific. A workshop with AC diagnostics is the safest bet to pinpoint the problem before throwing parts at it. Could save you money.

Thanks, I'll get a professional diagnosis to find the faulty part. I'm booking an appointment with a workshop specializing in car AC. Repair cost is about 1000€ for valve replacement and system recharge. Thanks for steering me away from wasting time.
