GM Homelink lights wont stop fast blinking

[jfred1212]

I have a 2007 6L NBS LTZ and this morning my GM homelink stopped opening both of my garage doors. When I stopped to try and reprogram, I noticed all 3 of the LED's were blinking fast like it was in programming mode. I cant get the lights to stop the fast blinking. I have held the outside buttons, pushed all 3 of the buttons separately, and turned off the truck, but the lights never stop blinking fast (even when the truck is off and the key is out). I waited 15 mins before I went back outsite and lights were still blinking.

 

I tried to actually program the buttons since they appear to be in programming mode, but they wont sync with the openers. Any ideas on how to get them to work or just stop blinking?

 

Thanks.

Nevermind. I dont know why I didnt think to pull the fuse out and put it back in. Once I did this, it reset the system and I was able to reprogram the system and open the doors. Still not clear why the it was stuck and blinking, but fixed now.

Happy you got if fixed so easily and glad that you posted the followup. It may save some other poor fellow a lot of anguish. But from experience, aside from the blinkers, a "Blinking" anything inside the truck usually means something bad. Glad yours was such a simple fix. Disconnecting the battery and waiting 15 or 20 minutes probably would have done the same thing.
