Battery light on in my 2004 pontiac grandam

If it needed boosting off it may be a bad alternator / battery or connection.

you could have a bad alternator not keeping the system at the appropriate level of charge. Or check the battery, replace with other known battery that is good and see if this fixes the problem. Clean all battery terminals. Dead shorts in battery can really create problems and sometimes can load test good but on the low side. Try the battery swap first if you have access to one

...hazard lights switch defective?

Any codes,engine light flashing,check battery,check spark plugs,fuel filter,vaccum leak.

Ground the a and b terminal of the aldl. Turn the ignition key to the on position, do not start the car. The check engine light will flash two digit codes. Example.....flash pause flash, flash, flash would equal code 13.

check for in line fuse from main fuse block on accesory side

If the security light is on, it can only be one thing. This light indicates a failure in the antitheft system that will eventually lead to your car refusing to start or continue running. Here is a link with alot of info, plus ways to beat this problem.

It could be the security system...It often times masks its self as a starter ignition or battery issue....If this is the problem turn your key to the accessory mode for ten minutes...have jumper cables and another vehicle on hand should your battery die...This seems to be a common issue on these vehicles but if this is the problem it should start after leaving it on accessory for 10 min

Replace the turn signal switch
