The first thing to check whenever you have any electrical gremlins is your battery. Let it sit overnight and in the morning, before you start the engine, use a digital voltmeter to measure the voltage. It should be at least 12.6 Volts.Whenever you have any kind of electrical problem, the first thing to do is to make sure that your battery is healthy and fully charged.

If your battery checks out OK, don't randomly change parts. See this thread for how to determine what's wrong and what to do:
