2002 firebird close drivers door lights go up and down alarm sets by it self, what's wrong?
you most likely have an exposed wire somewhere... wouldn't know where to start to trace that out though, trace it from your alarm system
I had a similar problem on one Firebird and the issue was ground wire that came from alarm module. On the second Firebird the problem was ground wire that came under the dashboard. But as Robert said - possible wiring problem.
