My 1999 Pontiac Grand Am SE 2dr 4cyl automatic transmission is messing
up. When I open a door, bump in to it, turn it on or do anything that
involves electricity the car lights start flashing and clicking and if
I hadn't turned of my alarm horn it would beep sometimes. It will even
start flashing when I come to a stop light, and the engine is still
running. It does this every time! My pass lock light on the dash is
constantly FLASHING. This all started happening a few months ago when I
let my friend drive the car and the battery just died, I replaced the
battery (but we accidentally grounded it when we hooked it up (positive
to negative and negative to positive, big spark)) The car started the
flashing and clicking 1 day before we grounded it. Did I completely
mess it up and is there anyway to stop the flashing and clicking? It is
driving me crazy. I have to turn my headlights on during the day so
people will not think I stole the car. Is this my passlock? I can start
my car every time and the passlock light is FLASHING not staying on
constantly. Can I expect my car to stop starting any day? We tried to
cut the yellow wire attached to the ignition but it didn't do any
thing because I can start it every time so I doubt it is my
ignition/ignition sensor. Please help I don't have the money or want
to spend it on a dealer fixing it. I keep reading about installing a
remote start to bypass the passlock but my car STARTS. What do I do?

Check the battery terminals for corrosion.
