Programming garage door opener-LED light issue

yellowcrow · 05-22-2020, 02:56 PM

I have a handle on what needs to be done to program my HomeLink buttons on the mirror but step 1 is clearing out the old codes. When I do this by pressing buttons 1 and 3 at the same time, the LED light doesn't light up. I can't get past the first step so wondering if anyone has an idea why the light wouldn't be working.

Update: I'm a dumb ass. All that was wrong is that the ignition was only in radio ready, not on. Once I started the car and did this the LED light was lit, programming done!

Does the LED ever light up? If not, someone may have replaced the mirror with the homelink version without adding the needed wiring harness. You can check your vin at the link below to determine your car came from the factory with homelink. https://www.mdecoder.com/
