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.
