Hi John, First let me thank you for the response and help with my problem. I don't believe the A/C pressure is all that low as the A/C will cool the inside down in short order. Granted it's not all that hot yet here in Arizona but it seems to be working well. Joe was saying that since I had fooled around with the switch "my words" it should be changed as it is preset at the factory. In short, what I'm saying is everything works well. It's just that before, the cycling was too quick " about every 5 seconds at idle " and now after I've fooled with it the cycling is a little longer between cycling at higher rpm's and still cools fine. However, I would like to know if I've done something that could damage the system? I hope you don't misunderstand what I'm saying. I like reading all this information about the system because it always helps to understand the systems on this car a little better. "then the less the AC low pressure switch will cycle on and off trying to keep from over pressure of the system. It's self protecting it's self." That's what I'm afraid of. Harming the system by messing with the A/C cycle switch as advised in the article. Thanks again and if you have the time please let me know what you think about this either on or off the list.
