There is a pressure sensor on your system. At low pressure your compressor won’t come on.

If you lean into the engine compartment from the passenger side to look at the pully side of the alternator, you will find a bolt (10mm I think) sort of behind the alternator and to the back left. It is sticking straight up, and you can use a nut driver or ratchet to turn it counter clockwise to loosen tension and lower the alternator. But you have to loosen the locking bolt first. When you look at the pully side of the alternator (once the plastic shroud is removed to expose the belt and pully) you will see 2 large bolts (one on the bottom right and one on the bottom left) on the alternator that hold it in place. The one on the bottom left (on the same side as the tension adjusting bolt) is the locking bolt. You will see that there is a track for it to slide along as the alternator swings up and down. If you loosen this bolt, the alternator should be free to swing down on the left side when you adjust the adjusting bolt. However, it is common for the alternator to stick even after you have loosened the locking bolt and . When I adjusted mine, I had to remove the bolt on the bottom right because my alternator had been in there so long is was stuck in place. (The alternator is supposed to pivot on the right bolt, but sometimes it sticks.)

One of your redundant magnetic speed pick-ups are bad. Probably a couple hundred bucks service from your dealer. Worth it. I also had a low idle problem when this happened; car would die at low rpm. New mag pick up fixed that also.
