ok so my a/c clutch is frequently engaging and disengaging every 15 seconds or so. A/C is still super cold but the noise from the engaging/disengaging is loud. I tried to recharge the a/c but seems like its not taking it but i know im doing it correctly. I looked at a pressure gauge and when the pressure builds up and gets higher it gets to a certain point and then the clutch will go on/off and then the pressure goes way down rapidly and then itll build up again. Repeats this not sure if this is normal but it does it within every 15 seconds cause a ticking noise very irritating i need help pleaaaaaase trying to get rid of that noise. thanks in advanced
