Vafa- If the ambient temperature is below 59 F at cold start, the compressor will not activate until the water temperature comes up to normal. At that point the compressor will activate and mix cold air with heated air to give the temperature selected on the climate control. If the temperature is above 59 F, the compressor comes on at engine start.
I had that written up earlier before I looked in the OM and deleted it. If you spring for the workshop manual sold by Ricambi, it explains all the details on the A/C system.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
