Try out these tips before going the replacement route; they just may do the trick:
Do a battery cable reset by disconnecting the positive and negative battery cables and touching them together for 15 minutes with the ignition switch turned to ON (II) ENGINE OFF. A battery cable reset forces all capacitors in that component to discharge faster, and it clears and resets the computer memory. If a software glitch is the culprit, a battery cable reset will fix the problem just as effectively as installing a new component would. Before you do this procedure though, make sure the battery has a full charge. A low battery can cause electronic components to not work right or not work at all.
Unplug the connectors from the component, wait a few minutes, and then plug them back in. If a poor connection is the culprit, the simple act of unplugging and plugging in the connector cleans the terminal contact surfaces and usually fixes the problem. While you've got the connector unplugged, look for witness marks on the terminals-they indicate a good, tight fit. If you suspect loose terminals, remove a female terminal and use it like a feeler gauge to check the fit.
