As I said, it's a commonly misunderstood item. Lots of ignorance out there. If you look up the word dielectric in the dictionary it means insulator. And it is. Dielectric grease is used to keep water out of connections, without shorting out anything. And prevent oxidation. Like on spark plug connections. Clearly a dielectric is not going to make anything more conductive.
Now electrically conductive grease is exactly what it says. It is conductive. The opposite of dielectric. You need to use it carefully and knowledgeably as it will short things out if misused.
For automotive interior applications that don't see water and weather, grease of any kind is rarely used. If that specific connector came with grease from the factory, they may have a good reason for it. Like cheap contact pins that may oxidize if left dry. So IF it did have grease originally, then yes you can use conductive grease carefully. Not dielectric grease. But grease will not cure a bad/damaged connector or pins. You need to fix the problem first and only then worry about grease.
Flush everything clean. Then de-oxidize with DeoxIT. Find and fix the mechanical problem.
