Check the vehicle grounds first. Make sure all are tight and not corroded. Then check all the fuses. Then, if they all are good, replace the Underhood Bussed Electrical Center (the box with all the fuses and relays). There have been some issues. Has anyone been trying to open the UBEC or do any testing on it?
