I’m trying to locate the ac compressor relay in my 2018 Yukon xl w/ 5.3 and 4x4. Anybody know where it is located? Thx.

I believe it is on the fuse box under the hood. But is soldered on the under side. We are having this same issue now for like a year. We have replaced the entire fuse box that kinda worked for like 6 months. The issue started up again and we now have no ac it would start and turn off randomly the last 2 months but it won't do anything now. Took it to the dealership this time and they said my compressor is leaking. So im not sure about that as why would a small leak would make this issue let my ac work work for a year then start to have problems once a month then to twice a week to the most working at all. Seems more like my compressor is not kicking on.
