Ford Ka AC Not Cooling

Sounds like a problem I had with my Ka. Does the AC make any unusual noises when you try to turn it on? Have you checked the AC relay and fuses? Also, check the AC diagnostics for error codes.

No unusual noises. Where's the AC relay located in the Ka? Any specific AC diagnostics tools you recommend?

The AC relay in mine was in the fuse box under the dashboard, but yours might be different. I'm no expert on diagnostics, but a valve defect in the AC system is likely. Since you haven't found a simple fix, take it to a trusted workshop for a professional inspection to prevent further damage. Could cost around 1000€.

Thanks for the advice. I'll schedule an appointment with a mechanic to check the AC system. Knowing about the potential valve issue and approximate repair cost is helpful. Thanks again!
