Clicking Noise When AC is on. Only works sometimes

731 Views 2 Replies 2 Participants Last post by  carocollins
Sometimes my ac will work fine and other times it will randomly start to put out hot air and start making a loud clicking noise every few seconds. I previously had issues with the evaporator temperature sensor having the wires come out. However that has been reattached and shouldn’t be the issue.

Here is a link to a video of the sound I recorded:

Any ideas of what it might be?
I have never worked on cars before so my knowledge of engines is limited.

I had the Freon checked today and it’s full. No leaks or anything. So that doesn’t seem to be the issue.

I’m wondering if it’s the evaporator sensor but if the wires had come out again it wouldn’t be working at all, not these random times of working and not working.

Any other ideas?
