Electric fan wiring question

[Fless]

There are two ground WIRES that are attached to ONE eyelet. Maybe the diagram at this site would help (if the PU trucks are the same), but I don't know in what year your harness was born:

I appreciate your help my harness is from a 2005 Tahoe, I screenshotted the diagram and I circled where I don’t understand, what is the 1 wire and is 2 the double ground that is attached to the eyelet

Your circled #1 is the power feed for Relay #3 which is half of the control for high speed fan relay control (Both fans on). Relay #2 is the other half of high speed control. Your circled #2 is indeed the double ground at the eyelet. This 2 wire ground is switched at Fan relay #3 and allows that double eyelet to provide the left fan a ground during low speed mode. Honestly the engineers overthought this setup and it is a dumb way to do it.

so, what I missing to run the double eyelet ground because from what I am looking at that is the only thing I'm missing, it looks as if they run into the black fan wire?

The 2 black wires in your pic that go toward the top of the pic dont have a ring terminal (eyelet) on them?

Your previous electrical diagram shows one of the ground wires coming off of fan relay #3 and the other black wire comes from the Right fan. The end of those 2 wires would then terminate into a ring terminal. So what is attached to your right fan now? Wires been cut?

^^^ THIS. I see only one black wire in the pic; what looks like another one is just a shadow. Extend the black wire from the right fan so it can be grounded with the black coming from the relay.




Find the black wire from the right fan, it should be somewhere in the harness, it looks like it may have been clipped inside.

I dont think the one black wire near the other is a shadow. The 2 are not bent the same in numerous places. Im curious if only one goes to the relay block in the pic and the other is cut and just laying there near the block. Cant tell in the pic.
