If the compressor cycles on and off, that sounds like your low on freon. Mine did the same thing. I recharged it and the problem went away for about two weeks. I heard a hissing sound one day with a smell. Come to find out one of the hoses that is in the back panel was loose at a connection. The o-ring held for awhile then gave out. Fixed the problem, recharged the system again, never had a problem since.

Thank you for your replay, but I checked the Freon and it is OK, and this problem happen only in the hot period of the day.
This morning I started the A/C both front and rear and it is perfect but after 10:30 AM the problem shows up when the temperature increase !!
Any suggestions ?

I'll give it a try and I'd like to inform you that I changed the compressor, tank and something they call it (the valve) as I remember it is a rectangle shape with 2 holes.
So what I have to do now if I want a cold air : start the engine, start the A/C (front) for a few minutes then the rear one
In the traffic turn the rear A/C off
Very bad situation

When you changed the compressor and other components, did you pull a vaccum on the system and allow it to sit idle for at least an hour? You may have air in your system either from the system leaking or you not pulling a proper vaccum. Your pressure in your system will read normal or a little higher than normal if there is air in your system.
