The left drivers side passenger speaker is the only one that works. I hooked a 10 watt generator to the rear sub-woofer and it squawked, so its a connection issue, not blown speakers. I understand the factory telephone mutes the other speakers during use. I subscribed to the mitchell service but it does not tell me where the telephone relay module is. Can you help me locate the box in my car? Or tell me how to disable the cell phone entirely, since the analog serivce is no longer available.
Do you

Hi - I have attached a couple of wiring diagrams and fuse locations. You might consider pulling the phone fuse. I show a diagram of the telephone/speaker relay but not the location other than this. Fuses And Relays: Are Located In Junction Blocks In Four Different Locations. These Locations Are As Follows; Behind Left-hand Side Of The Instrument Panel, Behind The Center Of The Instrument Panel, Left-hand Side Of The Engine Compartment And Front Left-hand Side Of The Engine Compartment. If this doesn't help, let us know and we will try more. You might also ask the parts department at the dealer for the print out of its location. There are times I have asked them to fax it to me for verifiation and that shows where it is also.
