Recirculating Pump - wont shut off. 850

posted by  someone claiming to be bob on  Tue Feb 18 13:37 CST 2003 [RELATED]

Relay stuck closed due to corrosion. Relay is located at the pump bracket under the battery. When the pump is in operation, the relay energizes the pump via unswitched current from the battery, therefor when the relay won't open, the battery drains. This can also happen to other relays throughout the car, but is most common with air pump and cooling fan relays.
