Purchased a 2002 Ody with the RES. Nice van with only 61,000 original miles. The problem is that there is no sound! The radio is unlocked and turns on. The DVD player turns on. But I get no volume from the speakers at all. I checked every fuse in the kick panel on passenger side. They're all fine. I removed the radio unit itself and looked over the connectors and wires. Looks fine. Any ideas?

*edit to add, its also completely stock. No aftermarket speakers or anything.

 

It could an issue internally with the audio unit, which you can either get repaired; or replace the unit with aftermarket or used OEM.

You've indicated you check the passenger side fuses. Also check driver side interior fuse no. 8 (7.5A).

If you want to do some more checking/testing:

1. Test to see if there is power at the wires going to the audio unit. You can disconnect Connector A in this test (optional test 2).

With a voltmeter, measure the voltage at Connector A terminal no. 2 (with ignition switch in ACC or ON position) and terminal no. 10 (should always be hot). With voltmeter set to 20V setting; Red test lead touching aforementioned terminals and black test lead touching chassis ground, such as a ground bolt or bare metal grounded bracket.

2. (Optional) Since the radio turns on, the ground probably is okay; but, if you like, you can test the Connector terminal 20 for ground by testing continuity to ground.
To test for continuity (testing if current flow through a wire or component):

1. Set to either the "ohms" or the setting it will beep when you hold the two leads together.
2. When you want to test a wire or component for continuity, touch one end of the meter's lead to one side of the wire/component; and the meter's other lead to the other end of the wire/component. In this case, touch one end to terminal no. 20 and the other end of the meter's lead to body ground.

3. For this test, you'll have to plug back in Connector A and backprobe the wire terminals. You'll want measure the voltage at terminal nos. 5, 6, 7, and 8. (Or test the speaker wires at the speakers instead.)

Backprobing:
If you have a voltmeter, you can test a few wires at the various wire connectors to narrow down the area of issue(s). You will want to backprobe a few wires. Backprobing is either using a backprobe set or using a thin needle or something and making contact with the metal terminal of the connector without piercing the wire in the back of the still connected connector. Care must be taken to ensure that the wiring does not get damaged. You can use something like a T pin, available at Walmart, etc., and backprobe. These pictures are just to give a picture of the concept of backprobing without piercing any wires.

Check the fuse on the drivers side. Not that. It was suggested to me that I also check the amplifier. Problem is that I don't know where it's at 😅

 

It doesn't have an external OEM amplifier.
