Intermittent A/C and Radio Function in Ford Smax - Need Advice

A/C System Not Engaging

I'm experiencing some issues with my Ford Smax's air conditioning and radio system. The A/C and radio seem to have a mind of their own - sometimes they work perfectly, other times they don't function at all. The fan control buttons also stop working when this happens. The duration of these issues varies greatly, from a few seconds to an hour. I've tried replacing the climate control unit, but it didn't solve the problem. Has anyone else experienced this issue or have any advice on how to fix it?

It sounds like you might be dealing with an electrical issue, possibly a loose or corroded wire or a faulty fuse. Start by checking the fuses related to the A/C and radio system. If they're fine, you might need to inspect the wiring. If you're not comfortable doing this yourself, I'd recommend taking your car to a professional mechanic. Please keep us updated on your progress. Do you have any other questions?

Thank you for your advice. We checked the fuses and cables first... We also tried replacing the IPC board, but no change.

Inspect the ground connections for the A/C and radio systems, as a poor ground can cause intermittent issues. Ensure all connections are clean and secure. If the problem persists, it might be worth checking the body control module (BCM) for faults. Let us know how it goes or if you have further questions.
