'02 300M "HomeLink" feature seems to be fading.
Our 300M's "HomeLink" (garage-door control) feeatures worked fine for a
long time but now seems to be losing its "oomph": even with the front of
the car almost touching the garage door we can't open the door with the
button in the car, but it still works with the remote that came with the
opener at a considerable distance. When the car is *in* the garage, the
buttons work OK.
Any history of the HomeLink modules' output power declining?
