Many people have upgraded the bass in their newer model Chevs/GMC/Caddys and have found that with that comes some new vibrations and rattles associated. Below is a run down how to solve one of those problem areas which is the homelink buttons. Problem: Homelink buttons rattle/buzz/vibrate with bass of stereo Vehicles application: Any with homelink buttons (example vehicle shown is a 2018 Suburban) Test: Turn it up (to 11 if you have to) and listen to your homelink buttons, or if you just lightly touch on them and you feel them very loose and not sturdy, odds are that is a source of one of your new rattles. Solution: Electrical tape and some minor disassembly of the overhead console and homelink buttons. Process: Step 1: Test it to see if you have the issue. I added a 10" sub in the back that now vibrated the homelink buttons on certain frequencies, very annoying. It also did the window switch buttons but that is a different fix although very similar. Tap on the buttons lightly, if they are wobbly and loose then you probably do or will have this problem, or turn the volume up with your favorite bass track and listen to the buttons vibrate. Example Image of this part on 2018: Step 2 (VIDEO): Disassemble the control unit. Here is a great little video on a 2015 Tahoe that is identical procedure to get the panel out that holds the homelink. Video Link: Overhead homelink removal Remember you will need to disconnect plugs before the cover panel will actually come out and DO NOT just pull down hard on the entire overhead console center. There are two screws (phillips on the 2018) retaining the full overhead piece in. Just open the sunglasses holder if you have it and we only need to take down the middle cover plate to perform this fix. Step 3: With the piece out on a workbench you can now disassemble the homelink buttons using a torx bit screw driver. It is very small and there are two screws holding the homelink into the cover/trim plate. Step 4: Is to take any decent vinyl electric tape/felt tape/flocking tape and add it to the trim plate like the below. You can trim the excess if you want to. The goal is to make sure you cover the bulk of the perimeter where the buttons themselves will rest against the cover/trim plate. The addition of two layers of Vinyl electric tape cured the problem I was experiencing. This additional thickness added pressure to the buttons mount tab itself which created a more snug and tight fit, that also made the buttons more rigid in the mount. Step 4: Reassemble the homelink to the cover plate, and then put everything back together in reverse order and you should now be vibration noise free at the home link button spot on your overhead console. Make sure to reconnect all plugs and test function before final pressing of the control plate back into the overhead console. Any questions let me know. I only had electrical tape to perform this task. I have some felt tape and flocking tape on order to do more vibration and rattle killing with the addition of the sub. Below is the two versions of tape I ordered that I will also have on hand other than black vinyl electric tape on this quest for vibration and rattle free music listening. J.V.

My 2012 GMC Sierra SLT has the factory garage door opener, which is the Lear product caller learcar2u. I have been using it ever since I purchased the truck new in 2012 and it worked fine with my 2003 Craftsman opener. However the circuit board went bad in the opener and parts are no longer available, so yesterday I had to replace the opener. When I could not get the truck programmed after about 9 unsuccessful attempts I called the help number in my owners manual, got a recording that the help line had been discontinued and to use the web site. So I went to the web site where they asked for the model number of the remote that I was trying to program and returned a response that it was incompatible and could not be programmed. So out of curiosity I tried several other manufacturer's garage door opener model numbers and discovered that the learcar2u transmitter can not be programmed for any of the new openers currently available on the market. A little further research I found that GM only used the Lear product through the 2013 model year and in 2014 switched to Homelink. Homelink is compatible and I had no problem programming my other car which deos have homelink. So I'm wondering if I can just purchase the transmitter for a 2014 GMC Sierra and replace only the transmitter in my truck. It's in the overhead console and appears to be similar in design. Does anyone kow if it will fit? I hate to spend the $100 for a part only to find out it won't work. Thanks.
I have a 2015 GMC 1500 and the other day I decided to set up the homelink garage door opener. I was quite surprised to find that it is functional with the truck off and the key out. I have 2 other cars with built in garage door openers and they are non-functional when the car off. I thought that was the whole idea behind having them built in. Then if someone opens your truck they would not be able to open up the garage door and gain access to your home if the truck is parked outside. Don't get me wrong I still love the truck it just surprised me this is the way GM set it up.
