If the Pump Does Not Function
WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
If the pump not work check that the wiring between the relay and the pump are intact and that 12 V and ground are at the connector.
If there is no current in the connector and the Volvo Scan Tool (ST) does not give a diagnostic trouble code (DTC) the relay is defective and should be changed.
If the pump does not work and there is both current and ground the pump is defective and should be replaced.
