So the radio turns on. I have display just no sound whether I use cassette or the radio. I dont want aftermarket because I like my car stock.
Does anyone have tips or can help with this issue? Thanks!
Anyone know if stock 93 came with an amp?

This is for 93 GT with 37K

Did the radio ever work? Or are you returning to stock?

Yes, 1993s with premium sound did have an amp located under the passenger seat. Silver box bolted to the floor pan. You can’t miss it.

Base model radios had no amp.

If you have premium sound, verify the jumper is in place behind the head unit. Give this thread a read. Post #6

Yes the radio worked till few months ago.
Just looked under the seat and I do have the amp there. In back of radio is 2 clips and antenna wire.
How it started was on the display I saw it kept switching from TAPE to RADIO but it still worked. Then just one day I had no sound. Display works and all the buttons work and I have checked fuses under the dash.
I will have to read through your thread but for the 93 if I did need to replace the radio, would the cd version just be a swap?
Id really rather just get this one working though cd would be nice.

Read your thread a bit and noticed a couple things. First I have the amp under the seat which appears to be the big one, not the football one. The other thing I do have the radio with manual eject.
And there is no jumper plug in my radio? Dont know if there ever was, doubt it just fell out recently if there was.

There were two premium cassette players, and one non-premium cassette. Your's is the manual eject premium. There's an electronic eject version as well.

Football amp is 87-92 only. 1993 has the bigger square amp

You should have a jumper. There's a way to bridge the pins to get it to work. Did it fall out? Check carefully back there and see if it's loose and behind the console. Without the jumper, you won't have sound.

Anyway called couple stereo places. One had no idea what the jumper plug was and other said it is for bypassing my amp. But like I said before I am about positive I never had that plug and radio worked fine.
In the meantime is there anything else that would cause me to lose volume? Could it have anything to do with display going from tape to radio?
I hooked it up again and with volume all the way up I hear maybe just static not sure but if i search stations i can hear a second of static as it goes through the stations and its very low.
 
It could also be that the radio is failing and needs to be rebuilt. There are shops that do this although I do not know any offhand.

The plug is not an amp bypass. That's the port used for controlling a CD changer or slave CD. If you look in the other thread, you'll see where the other poster bridged the connections to get it to work. You can try taking two flathead screwdrivers and shorting the same pins in the picture to see if the sound comes on.

When i pulled the jumper out of my radio in a test, there was ZERO sound.

Do a search on Ebay for this type of repair place... Had to have my dash computer and my radio done in my BMW and this was recommended on a BMW website... Seems to be a " mecca " of them in Texas.........

Ok thanks man. I just ordered the jumper. For 10 bucks its worth a shot I guess. Will be about a week or so.

Is there any explanation that my radio would work without this part though? I think you mentioned never seeing manual eject with the premium.
And I know its old af but the car only has 37k on it. Its really clean and radio is probably like barely used. Been in my garage for 10 years just start it up once in a while.
 
I haven't seen one, but I know they do exist.

The 1993 Cobra's all got this version. The part number for the electronic eject is F3ZF-19B165-AB. I don't know how it was determined what other vehicles got the version you have but I do know they exist. There's a non-premium version with a different plug setup on the back as well.



I really don't have an explanation of why it worked without a jumper. That's why my first thought was maybe it got pulled out accidentally. I have about 5-6 of the CD players and a few amps and they will not work without the jumper plugged in. Like i said, I tested this recently and no jumper = zero sound for me on any of the head units I had.

It's still possible that for whatever reason it was working and something internal has fried. Either way, if i had this radio in my hands I would try the jumper first.
 
So this one bugged me. But I found out why that particular radio works without a jumper.

I aquired the schematics for the 93 family of radios. It appears the Mustang radios are unique in that they have the jumper internally.

You’ll see below the internal jumpers (far left) so that’s why the external jumper plug is not needed.
