I replaced the radio in my 98 expedition and no sound from speakers

Question about 2004 Ford Expedition
1 Answer
I own an 05 Expedition with rear park assist. The system appears to be working, minus the actual alert sound. If I back up with the radio on, the radio will automatically lower the volume as normal so the audible "beeps" will be easily heard. There appears to be a TSB regarding the issue I described, the fix is to first replace the speaker that is attached to the module. Cheap enough to try, about $35 bucks. I have no idea where the module/speaker is located.

This answer was posted on fixya previously. So check for a TSB on your vehicle.

Check to see if your speaker wires are cut from the radio to the speakers. Not all of the speakers will stop working at the same time. On my 2001 expedition, the front worked but not the doors or rear. I found a cut speaker wire that is located behind the windshield trim above the stearing wheel where someone had installed an air freshener with a screw

First thing I would do is have someone qualified disconnect the alarm and stereo and start over.
Chances are you have circuits cross-connected and something is draining the battery.

According to ford truck forums online, the constant battery wire may be lite green and purple, the switched power may be pink and lite green, and the ground is black and lite green.
The battery wire is for memory.
Is that what you need to know ?

IF the coolant leak is on the right side of the engine near the top of the trans,inspect the coolant hoses for the heater core. This is common leak point on the 98 exped. Thankyou Please rate this info

what happened in my 2002 Exp, because they slam the door, the wire broke off switch that power downs the window, but if not that the switch mite be screwed, or you mite have a broken in the door where it opens an closes....

Did it fail while you had vehicle, or like this when you bought it? Could be bad radio or wiring harness was chopped up when previous owners had an aftermarket radio installed. They probably just slapped the OEM radio back in when selling car. And didn't put all the OEM wiring back in.
