    Are we under the hood or under the dash? Left side facing the windshield from inside or out?
    The questions above are pertinent but it sounds like all you really need to do is remove the part in question, clean all the contacts with a wire brush, scuff the mounting surfaces(both) and reinstall. Disco the battery first of course and it would be at this point that I would unplug your bulkhead connectors through the firewall, inspect, clean, dielectric grease and plug them back together. Wash rinse repeat your way around all the circuitry on the car right down to the bulb sockets.

    Get a picture of it, or describe it better. I usually use driver’s side / passenger side, and provide additional details, such as “The device is 2 inches high by 1 inch wide and the electrical connections are on the driver side of the box. The cover of the device is black and about 2 inches tall. It is mounted about an inch below the fire wall to cowl weld lip and is 3 inches from the steering column, towards the driver’s side of the car.”
