I have a 2005 F150 lariat screw. The door locks on both sides stopped working, the automatic lights won't work, the dome light doesn't come on when the door is opened, and the radio shut off when door is opened doesn't work. I've checked all the fuses, sprayed the locks with wd-40 and searched everywhere for a bad splice. I think its a problem with the bcm on the wall behind the back seat but don't know how to check it without going to the dealership. Any input on the issues would be appreciated
