Asked by for the 2002 Buick Rendezvous
The common leak for a Rendezvous would be at the condenser. If the system is low on charge or empty the compressor will not turn on. This is listed as a common problem by RepairPal, here is a link -

Your a/c system has a leak. low pressure switch is open to protect system so comp clutch not engaging. chk for leakage, perform necessary repair, replace accumulator, evacuate system, insure no more leaks( by maintainig vac for a period of time) recharge to proper level as designated. the system should now operate and run. note the low press switch is now closed allowing the comp clutc to eng!
thanks alot that helps too.
