2005 Dodge Caravan AC

Air Conditioning problem
2005 Dodge Caravan V8 Front Wheel Drive Automatic

Problem with the rear ac. The front ac works great but when you turn on the rear controls the ac quits working all toghter. The compresser cycles on and off. I have check the gas and it is in the good range. The check engen light is not on and I don't know if I can have the computer check and it will show a problem or not.

Thanks for your help.
