Have Ford Questions? Ask a Mechanic for Answers ASAP
Hi, I am Mike, welcome. I'm reviewing your question.
I can take a look at the vehicle wiring diagram, to see if there are any fuses or anything else to check but did the repair shop tell you that the radio does produce sound for them when they tested it?
Is this a base radio, bose, etc?
What engine came in this so I know I have the correct wiring diagram?
I see it as either wth or without Sony, is this an aftermarket Bose? If so, what was the oem radio?
Ok, I see several fuses, here are the wiring diagrams. Check all of those fuses with a voltmeter or at least a 12 volt test light when they should be hot.
That would include the #9, #19, #29 and #23 in the BCM, a the right kick panel. All hot all the time.
I don't know how to diagnose this any further. I'll opt out.
Was it a dealership or an independent repair shop that did the repair?
Did they have the ability to program the new radio (ACM Audio Control Module)to the vehicle with a scan tool?
The ACM is not just a plug and play radio. It is a self contained module that must be properly programed to the vehicle. It may work when first turned on, but after it resets, it will not produce any sound.
See the link below.
Yes it does. It shares information with other modules in the vehicle.
All They need to do is program it, which should only be at the most 1 flat rate hour. If they want more, then go to another dealership.
