2000 Quest with 200,000 miles. Added freon about a month ago. When I am at idle, with the AC “on”, I hear a sound that is like a “revving up”. It “cycles” about every 3 seconds or so. If I turn off the AC, it stops.
If you overcharged the system, there is an overpressure switch that will kill the compressor almost as soon as you start the A/C. Check if the compressor is cycling on/off. If could be overpressure in the system. Or give us more information about the symptoms.
It was my first attempt to add freon, and it is possible I put in too much.
The AC cools like a demon; would that be affected by the compressor switching on and off repeatedly?
