Welcome aboard!!
I am not familiar with the 4th Gens, but I believe the Homelink is the Homelink. In other words, there is no module. Sounds like the Vanity Lights & Homelink aren't getting power.
In the 3rd Gens, the Vanity Lights & the Homelink are powered from the battery saver relay.
Some have reported that the wire for the vanity lights gets pinched by the mount for the visors.
I would recommend checking all fuses in the interior fuse panel and the fuse panel under the hood.
