Hi there. When it comes to multiple systems and the electrical circuits malfunction, there is a power and ground issue. Check the battery cables and clean them with a tooth brush and baking soda with water. This will clean off any corrosion to the terminals. Also, check all of the ground wires to the vehicle, all grounds on the engine, body, fuse box, and computer. If you find a loose ground, clean it and then tighten it. If you find a ground wire on a painted surface, then remove the wire and remove the paint around where the wire mounts and then put the wire back on. If you see any wires that are green on the copper area, then the wire has corrosion in it and it needs replaced. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with your electrical issues.
