I’m trying to program a new spare key. I just tried to do it few minutes ago and it didn’t work. I went in this forum and read your post. Thank you for sharing it. I do have 2 known keys with me. Do you happen to know how to program it with 2 known keys?

2017 GMC Sierra 3500hd crew cab. Does anyone happen to know why the left turn signal for rv not working? Where under the hood can I find the main wiring leading to the 7 pin connector?

We bought 2017 Sierra 3500 hd few weeks ago. We took our RV for camping 1st time using the new truck. The ride was very bumpy the whole time with or without the RV. Is this normal or is there a solution for this issue? Different shocks? I apologize if this is a repeated issue in the forum. I appreciate the help.

Unknown. Bought it at eBay. Description said it fits 2014-2019 GMC Sierra 1500, 2500,& 3500.

Hi GMC owners, I’m not sure if this is the right place. Just bought 2017 GMC Sierra 3500hd crew cab. I need help installing the front seat lift spacers (see the attachment) and hope there is one of you who had done it. There was no instructions with it. I tried installing them and realized 2 things. 1. Nuts from the seat rails won’t fit in the spacer holes. 2. Bolts are too long. Either I’m clueless or I need to modify them. Please help. Thanks
