I had a horrible dealer experience dealing with this issue. If any of you are under warranty you need to demand the dealership replace the HMI at the very least. A new head unit demand next if even a single issue arises after HMI. This an incredibly common problem amongst GM owners across all platforms. The dealers know the problem and they know the fix, they just put you off as long as possible because I’m guessing the parts are expensive even for the them. The problem will not fix itself, it will not just stop happening. Have you ever heard of a electronic device that has issues and just makes itself better. They can do the updates, they can reprogram but it’s a equipment issue. The equipment is faulty and will not self-correct. Pulling the fuse, disconnecting the battery, etc will be temporary fixes, not long term. if you are out of warranty you can try buying a HMI interface off EBay or elsewhere on the web. If you can’t get it preprogrammed you will need to take it in and have dealership or other service place do it. Probably gonna cost $150 for just the programming at dealership, stereo shop may be able to do it cheaper. Unfortunately if this doesn’t fix the issue you need a new head unit. I would absolutely not buy a used one, chances of it develop it he same issue is very high. New ones are like $800. Your final option is to go through a company like Cruthcfield. I love that place. I priced out a new head unit, face-plate, all wires and harnesses to use the trucks existing controls, steering wheel, menu’s, etc. I think the total was like $850. Don’t back down if your under warranty. Do some cursory searches and you will find a ton of vehicles with this problem. Print out 3-4 and take em with you. Hope this helps.

I’m gonna bump this for all the new guys like myself. Paint stick worked like a charm. I loosened the nut and pulled the housing a little, made it easier to wedge the stick in there. Tightened it back, can’t even see it. Definitely more responsive, it’s not a Diablo tuner fix but it’s free and made a big difference. Nice job OP..

It works! I used 2 in-line splicers and a small piece of wire. Fogs now on with running, low and hi beams. Little green indicator lights doesn’t come on anymore and I can’t turn em off but those don’t matter to me. Thanks for the info.

Forgive my newbie ignorance all! I’m recently retired from the FD and have decided to start doing more of my work. To jump the 2 pins do I literally just need to stick a wire in the 2 holes and make sure it’s secured? Thanks in advance
