AC Blowing Warm

Hey Guys,

89 Olds 98

The AC on my car is blowing warm. Pressures are good on both high and low side. The system holds right around 25-30psi on the low side when the engine is slightly above idle and the compressor stays engaged. I'm thinking it may be a cloged orfice tube or the heater core isn't being blocked off.

Does anyone have an insight as to the inner workings of the ducting? I'm assuming the flappers are vacuum actuated? If so, does anyone have a vacuum diagram of the vehicle?

Any other inputs are greatly appreciated.

Thanks,

matt

recover and weigh the refrigerant- it is most likely low..find and fix your leak and evac and recharge to factory spec....
