A/C compressor switching on-and-off

[You Enjoy MyJeep]

Hey everyone,

I'm aware there are other threads on this subject, and I have already tried a few fixes. To start, I noticed a clicking sound going on and off inside the cabin, which sounds like it's coming from behind the glove box. Ultimately, this led me under the hood where I noticed the AC compressor coming on and off every few seconds. I tried swapping the hon and AC clutch relays, and that did not solve the issue. I then added some freon, but when adding it, it was already in the green zone. I then purchased an AC clutch cycle switch (low pressure switch) and high pressure switch. After installation, the issue persists. I have noticed the clutch coming on and off will go away after driving for a while.

I'd love to get some input from others on this.

Welcome.

A cycling ac compressor is typically due to a low charge, and having a qualified tech look at the system is a good place to start if ac is not your thing.

I'm getting a good reading now, and the AC is ice cold.

This.

I like to do things myself, when possible. Hence why I'm asking the forum. However, I may have solved it by removing excess freon.
