On a 2021 Equinox, my interior garage door opener worked for the first 6 weeks. Then last week it stopped.
I have two separate hand-held remotes and both still work (fresh batteries).

I have erased the interior buttons (holding 1 and 3 down until blinking) and no fix. I have attempted to reprogram the interior buttons using the hand-held unit ....the red light goes on, then slow blinks and then nothing (it should go to a fast blink).

Is there a battery in the interior controller ? Any other ideas?

no battery...its powered by the vehicle
does the garage opener (not the remote) need to be put into programming mode?

If the hand held units ( two of them) work properly, it seems to me the problem is the Equinox controller brain isn't recording the appropriate code.

It did function when I first bought the car and stayed working (when programmed by the hand-held units) until just last week.

I think I may have to take the SUV in to the dealer for warranty work.

I had an issue with my garage door after installing LED light bulbs in the opener. Some type of RF thing. Did you recently install LED bulbs anywhere near the opener?
