A noisy fuel pump is pretty normal, it may be louder in some trucks/SUV's than others. If you are hearing something else when you you turn on the defroster or fan, then it's probably the fan motor going out. Whatever the case, I usually just wait until it breaks before I fix it. About the only thing you can do now is check the blower housing on the passngr-side firewall for debris or rat's nests, and pull the motor to check the bearings.
