Premium sound radio repair manual

Anyone got a service/repair manual with schematics and parts list, for the early style premium sound radios (E9SF-19B165)? I'm trying to fix my radio and it would help a lot. I managed to find a manual for the CD player (E9SF-19B160) so i assume there is one for the radio too.

The manuals for the radios were issued by Ford to Factory Authorized Service Centers only. They were never available to the public, nor available electronically (PDF, etc.)

About the only way to get one is from a defunct Factory Repair Center that might be selling theirs on eBay. Every few years I see one pop up on eBay. E9SF would require a 1989 manual. In it you can find complete schematics and board layouts, component/parts lists, and detailed troubleshooting procedures. It includes sections for all radios and Cassette mechanisms Ford produced that year.
It is a large 3-ring binder with multiple sections.

It is far easier to find the service manuals for the CD players because the early ones from 1989-1993 were made by Sony-Japan FOR Ford. Sony was less anal about sharing their service manuals with the public.

I've got the Ford service manual for a '94 which I think has pretty decent diagrams for the JBL/premium audio system (which my '94 has)--I've got a different head unit than you with the new interior, but I suspect the JBL gear in the trunk is pretty similar? Let me know if you think it might help & I'm happy to scan/send some pages.

I'll throw out a second vote for Paul. He repaired my system last year after I had it in a box for about ten years after it quit working. Well worth the cost - it sounds better than new. Like 64th-35th I don't know the answer re: blue tooth.

UPDATE:
I did find the repair manual for both the stereo and cassette deck from ebay. Bought them and decided to try to fix it myself. So with the help of the parts list, I ordered the capacitors I needed and ended up replacing 40+ capacitors. In this radio, the faulty caps were green Nichicon, all the other brand or color caps seemed fine. I also replaced a burnt resistor.

It wasn't the easiest job with very limited experience with electronics and soldering AND the capacitors I ordered were wrong. They had the correct value, but some of them were physically too big because their voltage reading was huge (I didn't realise that the higher the voltage the bigger they were). So some caps I had to extend the legs with jumper wires and move them to a new location, because they wouldn't fit in their original place.

But today when I tested the radio to see if it works, to my suprise, it actually does! And it sounds really good, I wouldn't even wish for a better sound.

So these things can be repaired, it isn't easy and don't know if I would recommend it. If you value your time it will be cheaper to send it to Paul, but I learned something new while doing it so I guess that makes it worth it for me. If you want to try it yourself make sure to order the correct low profile capacitors, it will really make your life easier and the job faster. I have the service manual so if someone needs it I might help out

To those people asking about adding Bluetooth to these EPC (Premium Sound/JBL) radios...yes, it can be done, but the internal space inside the radios is VERY tight, making it a challenge.
I actually converted 2 units, last year, and it is not something I am fond of doing. It is very time consuming.
I made it so that Bluetooth pairing happened automatically once the radio was powered on, but in order to retain all other sound sources (AM,FM Tape, an CD) I chose to use the "DNR" button to toggle Bluetooth audio on and off when in AM radio mode only.
"DNR" stands for Dynamic Noise Reduction and I have yet to hear (or measure) its benefit in AM mode. There is a slight benefit in FM on weak stations.
So, with Bluetooth installed, just switch to AM mode, leave DNR off and you get AM, turn DNR on and you get Bluetooth music.
No external cables with buttons to push...everything is self-contained and no modifications to the faceplate are needed. (unlike many other implementations I've seen)

Congratulations on restoring audio in your radio!
Yes, the green Nichicon caps are the primary culprit for leakage, but other caps leak as well, those in the FM tuner, on the Preamp board, and the on Main Board. Many are higher value (larger) caps that are brown or black and once they start leaking, they can cause direct shorts and charring of the board directly under them, not to mention the eating away of copper circuit traces. This can lead to open circuits, or transistors, resistors, voltage regulators, etc, shorting out due to current overload.
