Adding Home Link?

Justin101714 · March 5, 2017

Same thing happening to me too.....

I have a 2016 Silverado 1500 LT. Bought an entire overhead console with everything already in it. Installed it, I get power to the home link system, but when I go to learn the garage door opener, the light never flashes rapidly, only slowly while trying to learn.....

where did you buy the console?

When I did this for my wife's traverse, the instructions in the owners manual did not work. I had to perform the pairing using the garage door opener instruction. Since moving to a new house, I have since decided not to use homelink on the traverse or my truck.

I spent time talking to Homelink on the phone. They tried everything They said they think the homelinks were faulty. I had 2 different ones from the same place and neither worked. That is why I wanted to know where Justin101714 got his. If it was the same place?

I bought mine off of eBay. I sent the other one back. Got another one and that one does the same thing, flashes slowly and never learns. These things should only require power and ground and everything else is internal to the module.

I've had the same problem. Bought from the same guy on eBay and then purchased just the transmitter from a separate vendor with no luck. When looking at the wiring harness , there are 3 wires going into the home link transmitter. Does anyone know if they are now trying to run this through the computer? Or have a wiring diagram? Was thinking maybe I can clip and retire if necessary.

stonephillips18 Is your truck a Silverado LT? TAZZIN Installed his piece by piece and it worked....why He has a video on this thread on page 3

2014 LT. I saw his video...Didn't do mine piece by piece, but purchased one on eBay that was already put together. Did you ever get yours working?

Hey ladies & gents,

Just to give a quick update on this, I know this is a bit late but for anyone else wanting to know this. You FIRST need to go to some place like www.gmpartsonline.net and drill down to you make/year/model and ensure there is a option for a replacement for the trim/harness/buttons/transmiiter for your vehicle, IF you DO see these options, you more than likely will be able to do this OEM style and not aftermarket (not guaranteed based on you situation). The transmitter for mine is as stated by another guy, that all is needs is power, it doesn't connect to anything else like the vehicle computer or anything, it is self contained. I decided to do the research on this after being told from the dealership, "You can't add this to your vehicle".. Upon researching this myself, I found I could buy a new harness (to have the OEM HomeLink plug on it), Trim plate (to be able to add the buttons), the buttons themselves and the transmitter. All in all I think I spent about 180.00 to keep it OEM. I WAS able to do it. I have a video that show tips and tricks on a 2014 silverado LT and changing the said above parts on the overhead console.. I made a youtube video on this make/model/color for my truck. I seriously hope is helps others wanting to do the same thing. I also upgraded my OEM 4.2" radio (i04) without OEM backup camera to a 8" (i05 - no nav) with OEM backup camera on the same truck. I'm getting together a small video on this as well and post it on my channel in youtube.

Some of us tried to install the homelink After install the unit lights up LED flashes slowly when trying to learn remote but never learns the transmitter code. Any ideas why? thanks

Yeah I figured power,light, and ground

Justin101714 · March 14, 2017

Never showed proof that it worked did he? the unit receives power from Fuse 3 left instrument panel fuse block, it's a 10 amp fuse. The circuit #240 comes down to connector x316, which is the headliner to overhead console harness, then continues to the module. It gets a ground from G210 which is underneath the dash extension panel on the passenger side below the windshield. His ground grounds multiple components. The unit is reviewing power and ground properly. There is an internal logic in the module that isn't really explained as to what it does, so I don't know if it keeps any VIN information or not. This module is not tied into any other modules, so I don't see how it would matter as far as any VIN information would go. The damn thing should just work.

I also read in GM service information that if you can't get the remote to learn to the module, you must program directly to the garage door opener itself. As in, pull the vehicle in the garage, but the learn button on the opening motor, you have 30 seconds to learn the vehicle to it. He garage door motor light should flash when learning is complete.

Homelinks only need power and ground to work, they are not on the CANBUS system. Make sure to hold the outside two buttons down for 10+ seconds to clear any stored memory positions. The light will flash fast once this is done. Then while holding the GDO opener below the Homelink module push the button on the HL you want to use and the GDO opener button at the same time. Hold them both down until the HL light flashes fast.

That part of the process only programs the GDO opener rolling code to the HL module, now you need to tell the GDO opener head unit that the HL module is a allowed remote. Press the learn button on the back of the GDO head unit and then press and hold the button you used in the above process on the HL module. If the process is done correctly the GDO head unit should flash the garage light to let you know the opener is programmed.
