I have tested the different settings on stereo but they seem to be ok.

Suggestion
I would first check balance and fader settings on the stereo, obvious I know but they could be different on different sources for the stereo.

Suggestion
I'd check the plugs at the CD changer (very easy), then the pins in the head unit (slightly harder as it involves pulling the HU), then continuity of the L/R cables.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hello guys!
Merry Xmas and all the best!
I am facing the weirdest of issues. I ve bought a C4S in October and I had noticed thag when using the cd-changer function i get no sound from front right speaker. When using radio it is working properly!
I have the bose system but non-most.
Any ideas on what can it be the issue?
Thought that maybe a connection from cd change has gone bad so i found the wiring diagram below
I tried using the following diagram but i cannot make sense what is the output of the cd changer. Also i see this LF right and LF left which i donot make sense. Tgought LF was for left front!
The wiring ypu have highlighted is from the stereo to the amplifier. This has 4 channels. The wiring from the cd changer to the stereo is on the left and has two channels. CDs have two channels of audio, it is the stereo which is converting this to 4 channels snd sending it on to the amp and then the speakers.
I would first check balance and fader settings on the stereo, obvious I know but they could be different on different sources for the stereo. If the other three channels are working and all four work on other sources it points towards the stereo to me. You could disconnect the outputs from the cd changer and swap them over just to check what happens. I am not sure what the stereo does with the two channel audio to generate the rear channels.

Thank you for your suggestion! The highlighted part was already in the image from where i got it! I have tested the different settings on stereo but they seem to be ok.
It is a mystery as well on how this conversion is done. I ll try to swap them over and see what happens then!
There are left and right channel connections at the CD player (RCA plugs) and the head unit (unsure on PCM but I'd bet on mini-ISO).
I'd check the plugs at the CD changer (very easy), then the pins in the head unit (slightly harder as it involves pulling the HU), then continuity of the L/R cables.
If there is nothing wrong with the cables then I'd try a different CD player (I have a spare you are welcome to try).
This is a source reference. Confirm exact model applicability in the original material.
