    Next, checked fan motor by applying 12VDC directly from an external power supply. Fan worked...

    Then I pulled the relay, checked all signals to the relay connector terminals, 12V from Battery, GND, 12V from ignition coil to energize relay... all checked out.

    Benched checked the relay. It closes when the coil is energized by 12V, however, could not carry the current to run the fan. Bad, dirty contacts.

    Is the plastic replacement a Bosch Brand as well . If it’s Bosch , what’s the Bosch part no. It’s usually stamped on the top .

    Thanks in advance ,

    You could probably pry the original relay apart and file the contacts.
