Intermittent Fault

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.

Fault-tracing indicates that the ECC control module registered a fault previously on the fan motor but the fault is now no longer present. Check that the fan motor in the passenger compartment temperature sensor is OK, the fan turns easily and that there is nothing in the way of the fan to stop it turning.

Remedy as necessary.
