I have a 2004 ES330 and the trunk release (either from inside the car or from the key fob) isn't working. I have already checked the "over ride" switch in the glove box. If I place my ear next to the trunk (around the license plate), I can hear a clicking noise inside, however, the trunk doesn't release. The emergency trunk release inside the trunk still works (it is a pain lowering the back seat arm rest and using a long broom hand to flip the emergency release). I have checked online and the trunk release mechanism (P/N 646003311-0) is $291.65. My question is, "Could there be anything else that could possibly be broken"? What else do I need to check? Any help is appreciated.... Regards, Jim
