You can start with making sure all connections are good and tight at the
battery. And since you have removed all relays and I assume you did this
with the key on you have set tons of fault codes in the BCM and PCM so it
will now make it harder for someone to diagnose this problem
I'll check the connections in the morning. I did not have the key on while
changing the relays. Since the electric locks should work without the key
on, I just changed a relay then used my FOB to try to unlock the doors. I
continued that process through all the relays in the PDC.
