Question about 2003 Ford Explorer
What would cause a rhythmic knocking noise that sounds like it's located inside the left rear panel of the car? Noise stops when car is off or when key is in the auxiliary position, starts as soon as the battery turns on or the car is running. Noise rhythm does not change with speed - the car can be at a complete stop and noise is still there.
It is possible that this may be your electronic fuel pump cycling on off to maintain fuel pressure. It may be an indication that the fuel pump is on its way out.... Have you done a trouble shoot with an auto manual specific for your Explorer yet? There should be a process of elimination guide or chart to help isolate the problem.
Hope that helps...=)

Hello,does this noise go away when you turn off the a/c?If it does,it is most likely your a/c mode control accuator.This causes a clicking noise when the a/c is turned on,or if your a/c switch is always on,as soon as you turn the key forward to the run position.
