Question
on my '91 Q45 Infiniti a loud unpleasant popping/static noise occurs frequently which is only corrected
by wiggling/diddling with the volume control; it sounds like the speakers will blow if I don't try to get the unit to stop.  Have you heard of such a problem?  Can the volume control knob be replaced to correct the problem?  The only attempts I have made to correct it is to vacuum the unit and spray compressed air in it because someone suggested that it was dust accumulating on some switch.  Any help would be appreciated.

Answer
only thing you can do is remove the unit, open the cover and locate the backside of the volume control, you should see a 'notch' in the control cover and spray lightly with a good quality control cleaner/lubricant such as de-ox-id, avail at most electronics parts stores. lot of effort, but that's the only way....lasts for years.....g....
