01 Electrical problems

Hi guys. I went to start the car this morning and I am having some problems that I can't figure out. The interior lights no longer work, the alarm no long sounds when I lock it and the windows stay cracked as if the doors were not shut. The brake light on dash is staying on and trunk and gas cap are not working as well as the lock/unlock buttons. HELP!!!! Any help would be appreciated.

Update. Realized I have a slight leak in the top by the back window. is it possible if the ecm got damp or wet it could be causing the problem?
