Technical Fiat Punto MK2 AC light not working

[VonNickstein]

Hello,

a friend of mine bought a Fiat Punto 2003 and we were surprised when we popped the hood and noticed the AC system.
The car was sold without AC, perhaps because it isn't working.
For some reason the light in the AC knob is not working, and the AC does not turn on.
When pushing the knob you can hear the compressor turning on (magnet valve) but no cool air and no light turning on.
Checked pressure in the lines, and appears to be OK compared to other cars.

Any ideas where to start?

You’d probably be best giving the car to an aircon person and letting them regas the system,

If the aircon compressor is Turning that’s a good sign that it needs a regas. The light could just be a blown bulb.

I’d get the aircon fully before worrying about the light on the dash
