Intermittent sound from RH speaker

[dimbim]

For years the sound on the right side has been less than perfect, now it is off all the time except on rough roads, when I get both channels momentarily. I am fairly sure the fault is not in the door.

I suspect a fault behind the radio/cassette unit, but a messed up, and poked the releasing screw behind the volume control out of sight, when it would not turn.

Has anyone had a similar fault and located something other than in behind the audio unit, or can anyone give me a solution to the problem of the missing screw please?

The intermittent fault on the right side speaker was easily traced to a faulty plug/socket down behind the audio unit. It wouldn't latch together properly, so I put a screw in the side of it. This has fixed a fault that was probably there since new, but would go away as soon as you start seriously looking for it.

You might find the radio removal procedure helpful.........

Because I poked the screw out of sight.......
We had to get a bit tough, and force the area, bottom left, out, so that we could see what the screw did.
We were able to operate the two latches, which travel laterally by the action of the cams on the screw.
What the manual does not make clear, (though it wouldn't have made any difference to me, because I was unable to make the screw turn) is when you have turned the screw, it has to stay at 90 degrees, whilst you pull out the assembly (using the cassette aperture as a gripping point) against the spring action of the 'flippers' on either side of the cassette box.
What the screw does is throw the latches that lock these springs in the out position.
I couldn't find the screw, so I have taken off the latches, and can pop the radio/cassette in/out easily.
