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.....

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.

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

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?

No purchased on ebay also got two of them neither worked weird Tazzin's worked

Yeah I figured power,light, and ground

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.

      Needing this part.

      By davester · Posted

      I'm sure if you went to a junkyard where you go in and pull the part off the truck yourself, not a used part place where they do it for you, you can get that part on it's own.  Depending on if and what else you would be buying, and time of day, they might even just skip over adding it as a item to the bill.

      I have an unused GM Authorization code.

      By davester · Posted

      It would be sold as a "kit", lights + auth/programming code.   You can resell the code to someone else, if they just buy the lights, either new or used, and they can then use the code to get them to work on their truck.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      Apologies in advance, this is a long post, there's a lot to explain.   A friend had a 2010 Avalanche with a 5.3 (LMG) that blew the head gaskets (amount other problems). He gave me a donor motor out of a 2007 suburban (LC9). I got it all installed, and everything hooked up. Went to go start it, and it stumbled a bit at first and died a couple times, but after trying a few times it sounded like it was running very well. Went out to go get some coolant, and came back the next day.    Upon trying to start it, the truck will crank and fire normally and the RPMs will raise to around 1,200 or 1,500, sounding great, and then the RPMs will decrease and it will just die. Repeat that a dozen or two dozen times, and eventually it will fire and idle beautifully. As soon as you touch the throttle, it will start misfiring and sound like absolute trash. When you let off the throttle it will come down and hunt around shaking and misfiring like crazy. A message will come up on the dash saying reduced engine power.    It is throwing codes for a map sensor circuit voltage High, as well as MAF sensor low frequency. With key on engine off, the map sensor reads about 4.8 volts on the vout pin, which the PCM interprets as about 17.8 PSI, contrasted to the barometer which my scan tool tells me reads about 13.5 PSI. However, once the engine starts and is idling this reading drops to about 5-6 PSI at a stable idle, and varies significantly when the engine is misfiring/ hunting like I said before. I should note that I used the intake and MAP sensor from the LC9 engine. I changed the connector on the 2010 harness to The 2007 connector. The pinouts for the sensors were printed right on the top, and I triple-checked that I put the correct wire into the correct place.   On the other hand, the MAF sensor reads consistently 0.0 g/s regardless of State. I have pulled my hair out trying to figure out this last detail. I have tried three different sensors, (all of which should be good, one of which was new), I have verified all the wiring from the sensor going back to the PCM, and have verified that the readings at the PCM are the same readings as at the sensor itself. The intake air temperature sensor is also functioning as normal. I verified all the voltages and grounds etc, and everything is as it should be. I don't have an oscilloscope to verify, but I probed with my multimeter (Klein mm720) on frequency Mode, and it reads that on initial cranking, the maf is producing between 3000 and 7000 HZ, and as soon as the engine fires that falls off to below, 1000, and if the engine continues to run, it will produce somewhat erratic readings between 5 and 100-200 HZ. It does increase notably when the engine is revved despite the misfirings. As I said before, I have verified all of the wires going to the PCM, and I have tried multiple known good sensors. I've tested all the pins and voltages from the sensor and verified them against the manual that they are what they should be. I tested all the wiring for both ohms and voltage drop, and everything tested fine. Like I said I tested at the sensor as well as right at the PCM, everything checked out.   The only other thing of note at least I think is the fact that the engine originally in the truck had VVT, but the engine I put in, the lc9, does not have VVT. I modified the cam sensor plug to work. I reference the wiring diagrams and double-checked that I modified the harness correctly to adapt it. There is obviously a code for the VVT solenoid, but I don't think that's the cause of my problems, and this friend will probably have the PCM sent off to tune out the codes at some point.   I'm writing this for my bed so I don't recall the exact codes, but I'll update the post tomorrow morning with the exact codes. And ideas or feedback much appreciated.

      It's possible the two trucks are using different body control modules which is why yours works and the OP's doesn't.   So much in these newer vehicles depends on model/trim configurations, production date. They don't all use the same modules like back in the day.
