I have a 2018 GMC Sierra 1500 5.3 L. A few weeks ago I slammed on my horn too hard and the horn wouldn't stop until I took the fuse out. If I put the fuse back in, the horn blows continuously so I have taken the fuse back out but now I can't use the horn. I would like to try and fix the issue myself instead of bringing it into a dealership but can't find any videos or tutorials on how to fix the horn button switch which I think is the issue.
If anyone has any feedback, please I'd appreciate something because I am not having much luck on my end.
If anyone has any experience with my situation please feel free to comment with any tips or your own experiences. I have 3" front 2" rear level on my 2018 silverado. I left everything else stock in the suspension and after about 30k miles I now have completely blown my CV joints. I will be replacing the CV axels, UCA's (recommendations?), and installing a differential drop kit this weekend. Hopefully this helps relieve the angles of the ball joints and CV axel. I've never done a diff drop before so wish me luck. Hopefully it's not too terrible of an install.

I have taken my truck to a couple shops but no one can seem to find what wrong with it.
When I come to a stop, my truck acts like it wants to stall out. It doesn't happen all the time but it is becoming more frequent. When stopping, the rpms die, all my gauges drop to zero and all my warning lights flash at me and turn back off. I don't have a check engine light on and when my truck is scanned, there are no codes that come up.
I have been told that it is possibly bad torque converter solenoids but I have a weird feeling that I might have some electrical gremlins somewhere.
There have been times where I am driving down the road and I go to make sure my windows are rolled up and the gauges due while rolling and my electrics cut out for a second and come back on.
There was also once where a truck pulled out down the road from me so I applied the brake to give them room and my truck downshifted hard and jumped to 3500 rpm and felt incredibly sluggish to get back on gas and up to speed.
Any help or any direction to a fix is greatly appreciated. Please help me find out what's wrong with my truck! Thank you!
Hello, I’ve got a 2008 GMC Sierra SLT with z71 package. I’ve had it stock until this year (2020). Recently put a level it in and had the truck aligned and it ran great. Went to put new tires and rims which are 33x12.5 Toyo open country AT2 extremes on 18x9 fuel assault wheels. The truck obviously had a decrease in power and mpg but recently it has gotten significantly worse.
On HWY I can get 18-16 but recently in the city I am getting 11mpg!!! I live in a city with a lot of hills and windy driving so I can attribute that to some of it but it seems low.
I’ve looked around and some guys suggest checking air sensors and tune ups, but I am wondering at what point is it a bigger issue? Or is it the reality of a lifted truck with heavy tires?
any suggestions are welcome, it has not been 11mpg for long just the last month. Thanks

So I bought this 2015 Sierra and it needs ball joints replaced. Only problem is I can’t get a straight answer about If I need new upper control arms or stock ones put back in. It currently has Rough Country arms but when I asked RC they told me that they should not be installed. ALSO I’m not 100% sure in the size of the lift. RC says it’s a 5” but it doesn’t seem like it. Just looking for some input. Thanks
