I just replaced my A/C system and there are no F codes popping up. I need to know where the relay is for the A/C compressor. Preferably a picture.

Hi,

It is in the under-hood relay box. See pics 1 and 2 below.

For some reason, I'm not showing the fuse box itself. Take a look at the two pics I attached and let me know if they help.

Let me know.
