For some time my programable "home link" system has acted strange. For ver a year it would only hold a programmed code for a month or so before needing reprogramming. A garage door repairman cleared all old links from the system which helped for a while, then it just stopped working, with no flashing lights when attempting to program, though the compass constantly displays in the mirror, after several months, I depressed the mirror button and my garage door open. It continued to work, without reprograming for several months and then suddenly stopped midday. It has shown no sign of life for the last 2 months.
Any ideas. The battery was replaced at a point in the erratic behavior, but it made no difference. Any ideas or anyone experiencing this problem.
