Question about 2000 Dodge Durango
Having a problem with the air conditioning, I have checked it for leaks with dye and there are none, i have pressure tested it and nothing wrong found, recharged it with r134a that is got from auto zone, and it it not cold at all, when i checked the pressure after the install it is way in the red when running I broungh the pressure down but it still spikes to the high. I am very confused here.
If pressure is in the red when engine is running and compressor is engaged, compressor clutch turning with pulley, and not getting cold air, it seems that your compressor may need to be changed. with engine running gage should read between 30 and 60 lbs.

Tips for a great answer:
MAF: A Mass Air Flow (MAF) sensor output that causes the PCM to sense a lower than normal air flow will cause a lean condition.
Air Induction System: Air leaks into the induction system which bypass the MAF sensor will cause a lean condition. Check for disconnected or damaged vacuum hoses, incorrectly installed or faulty crankcase ventilation valve, or for vacuum leaks at the throttle body, EGR valve, and intake manifold mounting surfaces.
Fuel Pressure: Perform a fuel system pressure test. A faulty fuel pump, plugged filter, or faulty fuel system pressure regulator will contribute to a lean condition.
Injector(s): Perform injector coil/balance test to locate faulty injector(s) contributing to a lean or flooding condition. In addition to the above test, check the condition of the injector O rings.
EGR: Check for leaking valve, adapter, or feed pipes which will contribute to a lean condition or excessive EGR flow.
Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.
