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.

Try jacking up the vehicle and putting it on jack stands letting the suspension hang down. Disconnect the battery for a few minuts and reconnect it and it should inflate the airbags and level off the suspension.

SOURCE: The rear suspension is down on my 1999 Ford

I had a 1999 Expedition. When you put the 4x4 on it raises the vehicle an extra inch or 2.
It may help to turn the 4x4 off. Two wheel drive is a lower air setting.
Your original pump may still be good. The problem can be in the front. The compressor is not filling the front suspension to the cutoff point. It will lift the rear after the front end is at running height. Since you lost the front end first, the remaining air bled out there and then the rear came down. Once you shut down the car the suspension was done, all the air was let go.
There are adjustment solenoids on the body but you need someone qualified to repair this.

SOURCE: i'm trying to replace rear speakers in my 99 ford

Ford usually fitted elliptical speakers in their models in the 1990's so it's possible that yours are 6"x9" or something similar.
You can get replacements from Ford, (which are usually very expensive!) or buy some better ones on the Internet, such as Ebay or Amazon.
I bought a pair of German Blaupunkt 6x9's for my car from some site I found on Ebay and the price was around half of that to buy the *same* speakers from Ford Spare parts Dep't!!!
The sound is fantastic!

PS: You should be able to access the rear speakers below the rear parcel shelf at each side of your Expedition. They are held in place by 4 screws, which usually have a Posidriv (+) type screwdriver head.
When refitting, make sure!!! that you fix the +ve spade terminal to the +ve marked on your new speaker & the -ve terminal to the -ve. Do this on both speakers to make sure that they are both in-phase (so both bass drive units are pushing air forwards together). If you don't keep them in phase, the speakers will produce much less bass - which is clearly noticable!

Hope this helps

2003 Ford Expedition battery died and when restarted, the radio won't work

I think your radio is much like the one in a Taurus, and mine has had hiccups like that before. First locate the actual radio which is in the back somewhere behind a cover. Unplug it and wait a few minutes to be sure it is reset. Plug it back in and it should work fine again. This may also fix your navigation system, if it doesn't find the 'brain' of the navigation thing and unplug, wait a few minutes, then plug it back in.

Rear parking assist problems

Try to determine if all the sensors are working correctly. This is where they have the most trouble. You will need a friend to help, but put it in reverse and stand to the side place your hand in front of them one at a time. I am guessing that either sensor one or four is bad.

Car Radio, Casette Player and CD Player not working

Hello Lei,

It sounds like the antenna has came loose from the back of the radio and the wiring harness is loose.

Make sure you have a good ground going to the radio, or this will cause a short and make the radio do strange things, the fact you sometimes get a signal tells me the radio is in working condition.
