headlights cycle when I lock car

What is your question?

I have a 2001 Firebird Formula and just recently the headlights will cycle when I lock or unlock the car. I also hear a loud motor noise in the right headlight which I would assume is the motor going out. I understand the motor issue and how to replace it. But, with all the firebirds I've owned, I've never seen the headlights cycle up and down when you lock or unlock the car.

How long has your 2001 Pontiac Firebird had this problem?

few days
