A slow sink can involve the disposal outlet or downstream waste route. A running motor does not prove that the drainage path is clear.
Say whether another sink bowl also drains slowly and whether water rises when a dishwasher empties. Those relationships can help locate the enquiry beyond the motor housing.
A photograph of existing pipework can help with access planning. Do not disconnect a full trap to create a view. Assessment should distinguish an appliance problem from a drainage restriction before work is proposed.
A sink that drains badly while the disposer runs may have a downstream problem. A silent disposer with a freely emptying sink points to a different enquiry.
