Hello. If both of these issues started occurring at the same time it is because there is an issue with voltage in the system. Most of the time on this vehicle it is caused by either a low battery, a failing ignition switch, or a bad connection on the negative battery cable. I usually start by checking the connections at the battery and the connections on the negative battery cable as well as load testing the battery. If nothing comes up then I do a voltage drop test of the ignition switch.
