Has anyone found a fix for this? I have a 2017 GMC sierra 1500 and have had to replace my driver side turn signal socket 4 times now with an AC delco socket. It works for a little while but then stops. I have found that the socket has a stopping point when installing it onto the headlight, I turn my turn signal on in the vehicle then I turn the socket slowly until it makes contact but over time it just turns with vibrations and loses contact. I finally bit the bullet and replaced the headlight assembly and the new headlight came with an aftermarket turn signal bulb socket and it does the same S@!*. I put on the new AC delco turn signal socket and the same thing I have to find the sweet spot until it loses contact again. I think its a poor design and needs to be fixed by GM. I have contacted the dealership and of course no bulletins or recalls. They told me to go and speak with a master tech to see if they know what the problem is. Any help. Thanks
