Default Electrical??? Or other

2003 LS, 3.4L
I recently purchased this car and I'm having a hard time finding out how to fix my problem. Car starts and runs like should but I have 2 warnings lights that stay on, "battery"(red) an "security"(yellow) and occasionally "service vehicle soon" comes on too but usually it goes off after restarting car. My high beams works fine but the indicator light may or may not. Climate control fan switch works on 5 only, can not switch from recirculate to fresh air. And the radio connector does not have power on the (red) switched 12v wire causing radio to have to be manually turned on/off. I have replaced BCM, checked and replaced fuses, relays, new battery, alternator tested good, ignition switch, and I'm currently checking all ground wires(that I can find) for good connections. Any other suggestions on what else to check???
