well, its not cycling on and off like crazy but its still not as cold as it should be and when the compressor engages it vibrates quite alot, more then i remember. i was riding around in 72 degree heat, full sun, a/c cranked to max with the air circulating instead of fresh, and even after 20 minutes, it still didn't cool down like it should. is this strictly a compressor problem? did putting the compressor through the extra stress of not having a constant power supply level from the battery cause harm to the compressor?
