Hi,
vehicle : ford falcon bf 2005 petrol and gas (vapour system)
The other day my yellow engine light(emission light) came on while I was driving and then went away, that week I noticed my a/c stopped working, and just started to blow warm air, also noticed my a/c compressor clutch doesn't engage.

Could you please diagnose this please?
Have I lost all my refigerant in one go?

One thing that I havn't changed on the car is air filter, and that could be dusty too.

The yellow light has to do with fuel control, not ac. You have 2 separate issues here. You may be low in freon for your ac.

The light, you need to have the code pulled for us to further assist you.
