Radiator fan runs after shutdown, drains battery

Radiator fan runs after engine is off and drains battery

If you own a Chrysler minivans and the radiator fan runs after shutdown and drains the battery, read this. Some late model Chrysler minivan owners may experience a problem with the cooling fan running after the engine is shut down. That, in itself, is not so unusual—many vehicles do that. But when the cooling fan relay gives up the ghost, the cooling fan runs all the time, draining your battery. Diagnosing the problem is easier than finding the relay. Chrysler place the relay in front of the A/C condenser, right on top of the bumper reinforcement. It has a spiked heat sink that needs airflow to cool the relay—that’s why they placed it there. Remove the grille and you’ll see it.
