2003 Santa Fe Clicking Sound in the Rear of the Vehicle
 

I recently noticed a clicking sound (sounds like a relay) coming from
the back (somewhere behind the front seats) of the car. The noise
usually occurs when going over bumps in the road. If searched
HMASERVICE.COM but cannot find any relays in the back. I removed the
rear hatch panel with the car running and tried knocking on things but
no luck reproducing the sound.

Any ideas are greatly appreciated.
