M35x AC troubles

[dpack]

The AC on this car periodically stops working for 10 to 15 min. It keeps blowing air but is not cooling. After several minutes it kicks back on and works fine. After this happens if I turn the car off I can hear a loud moaning noise coming from the engine compartment and a burning smell. Dealer can't replicate the problem so won't honor the extended warranty. Anyone have this issue or have suggestions?

Sounds like your AC system is overcharged and therefore the pressure solenoid tells the AC compressor clutch to turn off. I suspect the burning smell is from the belts trying real hard to turn the AC compressor with such a high pressure buildup.
