I set up my homelink yesterday afternoon, since then my garage door has gone up by itself 6 times, randomly, and only when the escalade it parked in the driveway. Now I have lived in this house for 4 years, and this has never happened before. It started within 1 hour of me programming the homelink, and did not happen at all when I was out with the car yesterday or today. Am I crazy or does it seem like escalade is doing it while it is sitting there, I dont see any other explanation. Has anyone else had this problem?
