Had the visor/homelink buttons replaced last week. Still does not work. [B][U] Have probably tried to program 5 X's since and have been up and down ladder to press the "learn" button on the opener another 5X's. I live close to the dealer, so I'm not giving up. Ridiculous!
2nd update: I'm scheduled for a 2nd visit tomorrow. In one last ditch effort yesterday, I tried programming the Homelink button one last time. Guess what? It worked (for now). I'm not even sure what I did differently, if anything, to pull this off. Anyway, I have a secondary issue to be taken care of, so I'll discuss this Homelink thing with them again. They've been very cooperative, but I'm not sure they know anymore than I do when it comes to Homelink settings. Thanks to all of you that have responded.
