4wd is a different issue. It's referring to your fan clutch, the connector is on the drivers side hooked into the fan shroud. Just check the connector and the wires, if all good, it's probably your fan clutch assembly that needs to be looked at. Normally when the fan clutch goes, it's loud all the time. Or will do it intermittently when it's not supposed to. Pretty common for the I6 engine.
