In the last month or so, I've noticed that when hitting the remote to enter my TL-S and opening the driver side door, I hear a beep. This usually means that something has reset. I now have to adjust my passenger side programmable mirror every time I get into the car. Why is this and what can I do to fix it? My car was sold to me with only the #2 remote, but this shouldn't make a difference....or should it? To play it safe, I have #1 and #2 memory set to the exact same seat and mirror positions. Am I losing my memory?
Thanks.
