A4k Left Mouse Button issue

[Tension]

Caps.

@Tension: failing caps usually affect the CPU (3640) or sound circuitry. Are those leaky bastards near the CIA's too?

Not sure, but my A4k has a problem with the right mouse button jamming on, even without a mouse in the port.  I also have bad audio and random crashes.  Plus the Parallel port causes a printer to start printing random nonsense.

I put it down to caps, but one of the CIAs is probably buggered as well

Yup caps can be an issue, got an A1200 that has a very similar problem to your A4k. I'd put money on saying its a fault with a cap.

Just heard about the £30 capacitor replacement service by AmigaKit.  Might take them up on that offer because I wouldn't want to risk doing it myself.

The steaks are too high.
