Oldsmobile Questions? Ask a Mechanic for Answers ASAP
Hi my name is***** will be glad to try to help. What year is your Brevada? Also can you go over some of the things that have been replaced in the AC circuit? If the circuit runs as it should and the pressures are in specs while monitoring with guages installed and there are no restrictions in the system, the condenser is not plugged and has good air flow check the evaporator core for freezing up if the system is fully charged for you problem and also verify the blend doors are working properly and not sticking when switching hot to cold. Let me know
