Ford F AC Not Cooling

My 2003 Ford F with a gasoline engine has AC issues. The air conditioning completely stopped cooling, and the system won't even switch on. I suspect a defect in one of the valves. Has anyone dealt with something similar? My F has about 204793 km on the clock.

I had a similar issue with my old Opel Corsa. The AC just quit, and it turned out to be a faulty pressure switch. This switch prevents the AC compressor from running when the refrigerant pressure is too low or too high, protecting the system. Could be worth checking out on your Ford F too!

Thanks for the info! Where exactly is the pressure switch located? And is there a way to test it without specialized equipment? I'm comfortable with a multimeter, if that helps.

On my Corsa, it was near the condenser, which is usually in front of the radiator. As for testing, you can check for continuity with a multimeter when the system should be on. If there's no continuity, it's likely the switch is bad. But honestly, AC systems can be tricky, with different pressures and refrigerants. It might be worth taking it to a workshop to avoid messing something else up.

Appreciate the advice! I think I'll take it to a trusted workshop. The repair ended up costing around 1000€, which included replacing a few faulty valves and a recharge. At least it's blowing cold air again!
