1999 Pontiac Grand Am Electrical Problem

My car will not lock with either the remote I have put in or the automatic locks located on my door. I also cannot pop my trunk with the remote or the button on my door. Random lights are on my dash (low coolant, low washer fluid, trac off, seatbelt) and do not go away. Although the seatbelt light goes off after about 30 seconds. My daytime running lights don't work, automatic lights do not work, fog lights do not work. I was told it might be my ecm box.
