I have a 2004 Expedition. I checked all four backup sensors and they are clicking when I check them in reverse with the ignition set to on. The stereo lowers, but there's no beeping sound indicating proximity. Any suggestions?

Are you the original owner?
If not is it possible that the speaker has been disconnected or silenced?
Also check the setup in the message center to see if the speaker has been disabled.

Thanks for your help. I found it. It has the speaker attached to the module. I might have to replace the entire module because I can't find the speaker that is sold separately. Thanks again for your help!
