I've tried using the search but haven't found the right answer yet. Ok so basically went I try to turn on my radio everything turns on and works including AM/FM/CD changer and clock, but there is no sound. My speakers just aren't playing and I know they aren't blown, I'm confused, last time my radio stopped working nothing worked not even the display. All I had to do to fix that was change a fuse but none of them are blown this time. I can even change the volume, change stations, and change songs on CD but there is no sound

yes i checked but everything seems to be connected fine. Is there a fuse that goes to the rcu specifically?

Ok so I went out since the weather was nice again, and decided to check every fuse in the car I could find. All the fuses were fine, none what so ever were blown. Now I'm getting pissed. I have no idea what's wrong with this thing. Is it the infamous ford wiring, and something shorted out. I really don't want to take this to the stealership and get ripped off with some ridiculous expense for replacing something cheap. Could it be my Rcu. I don't know why it would have just randomly stopped working and seeing as everything works except I guess signal to the speakers, I figure it's not the Rcu. The only conclusion I can think of is the wiring somewhere shorted out. And other ideas, I mean anything I need my radio, this whole no music thing is killing me.

I actually just tried that, and unfortunately it didn't work. This is getting ridiculous. And I just finished up sealing my sub boxes and spraying them with sound deadening, then stuffin it with some polyfil. Now I can't even hear what the difference is until I figure out what's wrong with my damn radio.

Does anyone know how much an RCU goes for at a junkyard? You could always go for a junkyard RCU. I'm sure most, if not all of them, are still good (unless they've already been picked or the car was rear ended badly or something).

Just because the display works does not mean the radio is working. You could have a blown capacitor. Common problem on car radios. Pop your radio out and send it here
http://www.instrumentclusters.com/

They fix it in 24 hrs and send it back. Ususally around $100 or so for the fix.

Thanks for the link. I just sent them an email about my issue with the radio. If they say they can fix it, then I'll send it to them. Unless of course I am the highest bidder on this replacement radio on Ebay, if I win it then I'll try switching out the radios first to see if that works, it that doesn't work then I'll fiberglass the replacement so I can install my alpine deck into the dash since I like it a lot more than this stock radio.

Ok, it looks like some clarification is needed here.

Your radio has two components to it. The head, located in the dashboard, and the RCU, located in the trunk on the driver's side, IIRC. The head contains all of the controls, and the tape deck or CD Player. The RCU contains the amplifier and the tuner.

Given your failure mode, there is a high likelihood that the issue lies with your RCU. They're relatively inexpensive at junk yards and on eBay. I'd start there before anything. Failing that, there's a smaller chance that you have a bad MLPS. If jiggling the gear selector, or changing between ranges allows the radio to work, then this could be the issue as well. I'm hesitant to say it's that however, as a MLPS failure is also accompanied by strange transmission and sometimes steering behaviors.

My friend's '99 Taurus was doing the same thing. In his case, the antenna somehow came unplugged in the trunk. You probably checked that already but if you didn't I thought I'd throw in my 2 cents worth. Good luck, it'll be interesting to know the final solution.

yea still no luck so far, checked the antenna again with no change. Thanks for all the recommendations though. Atleast I know I'm not missing anything. :) So most likely the RCU then? I've already taken the radio out so atleast I should be able to hook my CCFL's tomorrow with plenty of room. Anyone have any other ideas of what's wrong with my radio or have any suggestions on mods and what I should do while it is out. I wish I could get a huge screen in there and still be able to control everything the stock one did only is be touchscreen though. That would be cool.

Ok so now this gets weird, I got the new radio put it in and guess what it still didn't work, so I put the old one back in, just because its way cleaner than the replacement I got, and it still didn't work. No suprise there. But I guess I accidently left the radio on when I shut the car off even though it doesn't work. Then when i turned the car back on after work, the it was working. Of course I didn't even notice it so I turned it off so I could make a phone call. Then when I got off the phone I turned it back on and it worked, still not really paying much attention to the fact. Then when I finally realized it I turned it up just to be sure I wasn't imagining it, and it was really workind. Then I turned it back down to a tolerable level, and it started only playing out of the right side speakers. So I shut it off to see if that would fix it and now it doesn't work again. Now does anyone have ideas?

Loose or corroded connectors at the RCU in the trunk? Did you ever check it? The leftmost connector has the power supply and all the speaker wiring. If the radio is changing channels etc, the middle connector is likely OK.

Yea I checked all the connectors and fuses, non were loose or blown. I guess I need to get some electronics cleaner and give that a shot, couldn't hurt.

You have a good idea there, somekind of electronic/contact cleaner. There's stuff you can buy that's called a "contact enhancer". We use one at work called Stabilant 22 but at $40.00 for a small bottle it's not one for the average home/car repair.

It did the same thing tonight and I'm not completely sure yet what the problem is, this time when I turned it up it was fine, but when I shut if off I couldn't get it to turn back on. But I do have some terminal cleaner in my glove box for my battery when I was having connection issues before, is that safe to use. I figure it would but I'm not totally positive since my battery isn't quite as sensitive as a lil plastic connector.

I had an issue with my radio not as bad as this one but it may help some.

It ended up being a bad tweeter on the door pod. there was some sort of issue in the speaker itself that started to cause the whole left channel to fade out. Mostly the tweeter didnt work. I finally got a replacement at a car recycle yard. It helps if you have a multimeter you can test the resistance of the speaker coils to see if you have a bad one.

Also, remove and replace the connectors a few times on the back of the headunit and RCU if you have not and see if that helps.

I thought I was going nuts with mine. I would pull the door pannel off and check the connection to the tweeter.. drive around and everything would be fine. Then I would put the panel back on and the next day the tweeter would not work again. I even cleaned the contacts with some sandpaper and same thing. Not sure what happened to it but I guess it decided to die that week.

I'm not sure if this was related to the tap issue I was having where the left channel was low output. It seems to work fine now although I think sometimes it is still not all there but it may be the tape.

I did find a Mach RCU at the yard and installed that.. but the gain was too high and where normally i would listen say.. at the half mark, it would be way down with only a few dots to be as loud. Also pickud up a lot more cell phone interference that the stock (as well as ipod harddrive noise) That alone would have made me take it back but it also had an issue with one of the channels sorta fading in and out with heavy bass..

Needless to say I took that back and am using the regular RCU still. Works fine for me.

I'm going to try to get take another look at everything after I get off work this afternoon, hopefully by 4, maybe I'll have a bit more luck with it. I guess while I'm at it I should go ahead and replace all my speakers since the new ones are all sitting in the back seat. I bet my 6.5" alpine type x ref's will sound pretty good when I get this problem taken care of.

Well I've done everything I can think of and and nothings worked so far. It still randomly plays music but after I shut it off it doesn't work again so I have no clue what's going one with it, I guess I'll just start putting in all my speakers and then take it in at some point if no one really knows whats going on. I've got all the speakers I need so I guess I should just go ahead and put them in whenever I get the chance. I'm still open to any suggestions though.
