Ill have to check them the next time I do an AC job. Again Iam not trying to argue with you or anyone else, just telling what I have ran across at times. I did repair a 96 F-250 last week and it did not have an ajustable low preasure switch and it cycled at 24 psi, and had ice cold air. No biggy just seen a few of them do it, most of them have been farm trucks and tractors that have done, heck who knows the evap cores may be dirty, espically on the tractors.
