If the volume control is scratchy or noisy, first try spraying a cleaner+lube inside the wafer. Like Caig Deoxit D5. Don't use WD-40. Check for cracked solder connections to the circuit board. These are common car stereo volume control problems.

Otherwise, the potentiometer is likely a custom part that AC Delco uses. That would mean pulling the control out, and doing microsurgury to fix it, or getting one from another 2700 radio which was used for many years in many GM's.

If the unit powers up but is dead quiet, the volume control is probably not the problem.
