Hi guys! Help needed. I apologize if this has been posted somewhere else, I searched and couldn’t find it. I’ve got a 2018 Yukon Denali AWD. I’m looking for the OEM part numbers for both upper and lower ball joints, but can’t seem to find them. All I keep finding is the entire replacement control arms with ball joints. Does anybody happen to know them? Aftermarket replacements I’ve been able to find, but I’m nervous going that route. Unless maybe you guys have a solid recommendation on aftermarket replacements? Either way, any help here is appreciated! Last 5 of vin: 90997

Thank you guys for the help! And my apologies for the late reply, but wanted to follow up. These dealerships are really something else. I went and changed out the fuse box. This still did not work. So I finally caved and brought it in to the service department. After paying $300 in diagnostic fees, they told me they could not locate the issue and would need to just start changing out parts until the problem was gone. At this point I was so frustrated I decided to take the horn apart myself and have a look. Within seconds of opening it up I was able to see that one of the little metal tabs that make contact and activate the horn when you press it, was slightly bent. I used a tiny screw driver to bend it back into place and voila, problem solved

Recently broke the horn in my 2018 Yukon Denali. Hit it too hard (I know, I'm an idiot). Horn got stuck on and it ended up blowing out. Took it to my mechanic (not dealership). He advised me that I needed to replace my spring coil as well as the actual horn. Fuse was fine. After replacing both, he went to reattach the battery, and as soon as he put those cables back on the horn just starts blowing without stopping. Tried hitting the lock / unlock buttons on the remote. Tried pressing the horn on steering wheel. Nothing stops it. I've had to disconnect the horn and go without since. Knowing that the horn, fuse and spring coil are all good, he assumed it must be the relay. Problem is neither of us have been able to find where the relay is located. I have searched the internet to no avail. What I did read on one or two forums is that the horn relay could be built into the fuse box under the hood. But nothing confirming this. I've called 3 different dealerships and spoken with parts, as well as service departments. None of them have been able to tell me. The last one I spoke with said to call GMC direct. I spoke with them and they also were unable to confirm anything. So before I go and replace the entire fuse box, does anyone know if this is true? Is the horn relay on my truck built into the fuse box itself? Or does anyone have any suggestions for any other diagnostics I should check before replacing the fuse box? Very much appreciated! -Travis
