I’ve been searching around, but I haven’t found a solution that matches my exact problem.
My Homelink LEDs won’t light up, and Homelink itself isn’t working. Also, the driver’s side vanity light doesn’t turn on, although the passenger side vanity light works fine whether the doors are open or closed.
I think fuse 1 in the passenger fuse box is for both the Homelink and the vanity lights, but only one light is out, so I’m not sure if it’s a fuse issue. Unfortunately, I’m having a tough time checking it because of some back issues.
Is there a separate fuse that might only affect the driver’s side or Homelink? Should I try something else before replacing the visor? Open to ideas! If anyone has advice or knows the part number for the visor, that’d help too.
Had the same problem on my 2015! My wife uses the visor a lot, sliding it in and out against the driver’s side window to block the sun. I took it apart and found the power wire was cut inside the tube where it slides back and forth. I managed to repair it with some spare wire and low-melt solder, but it happened again about a year later.
Honestly, it’s a poor design having the wire inside the tube like that. There’s a connector behind the headliner with a couple of bolts holding it in place. It’s been a while since I did the fix, but maybe this info helps.

Thanks for the details! I’m working on getting a new visor. I just hope I don’t have to pull the headliner out to swap it.
I think you’ll be fine. The plastic cap pops off the end of the visor stem where it’s attached to the roof, and it reveals two bolts. I was able to unplug the power connector by carefully moving the headliner aside a bit without actually removing it. There were a few YouTube videos that showed this too.
Just a heads up: the lights and Homelink run through the body control module (BCM). A lot of non-powertrain systems like locks, lights, windows, and audio are managed by that module, which can fail from time to time.
The visor only has a single power connection, which feeds both the vanity light and Homelink. There aren’t any data or signal wires in there—Homelink is fully self-contained and doesn’t communicate with the vehicle’s other systems.
Since the passenger side vanity light works, it’s likely not a blown fuse. Possible causes could be:
A loose or disconnected power connector above the headliner.
Nope. At the time, I had a bad relay, and the fuse for my cross-traffic sensors and rear camera kept blowing. I replaced the relay, but the fuse issue remained, so I just ignored it for a while.
I revisited the fuse problem recently, put in a new one, and now everything works except Homelink. Tried re-pairing Homelink the other day, but still no luck.
In my case, I heard a buzzing noise coming from under the hood, which tipped me off to the bad relay.
After replacing it, I had issues with the camera and sensors, so I checked the manual to see which fuse was related.
You could test a relay with a multimeter, but I doubt that’s the root cause of the Homelink issue since I still have that problem even with a new relay.
It could be more than just fuses or relays. Modern vehicles use a body control module (BCM) to manage all sorts of things like lights, doors, audio, windows, and even Homelink.
If replacing fuses and relays doesn’t work, the BCM might be the next thing to look at.
Yeah, it’s hard to pin down. Once you’ve checked the accessible fuses and relays, if the issue persists, it often comes down to wiring or a possible BCM issue. Only a good technician can confirm that.
I once had a problem where my horn wouldn’t stop blaring. Pulling the horn fuse was a temporary fix, but it meant no horn at all. Turned out it was a BCM problem, and replacing it with a remanufactured unit solved the issue.
Basically, anything that isn’t powertrain-related—lights, horn, doors, locks, radio, HVAC, remote start—goes through the BCM. If checking the fuses, relays, and bulbs doesn’t solve it, the BCM might be worth considering.
