To find the RADIATOR COOLING FAN MOTOR RELAY, we need additional information about your 1995 Oldsmobile Aurora 4.0L SFI DOHC 8cyl. Please select one of the following:
The Radiator Cooling Fan Motor Relay is located: Under hood, passenger side, upper firewall, mounted in corner in relay block When testing a cooling fan switch, first test it with the engine cold, then test it when the engine reaches a specified temperature. Check your vehicle's service manual for more directions. To check a switch, disconnect the connector at the switch. with an ohmmeter, check for continuity between the terminals of the switch with the switch moved to the on position and to the off position.To find the RADIATOR COOLING FAN MOTOR RELAY, we need additional information about your 1995 Oldsmobile Aurora 4.0L SFI DOHC 8cyl.

The Radiator Cooling Fan Motor Relay is located: Under hood, passenger side, front side of wheelwell, mounted in relay panel The continuity through a switch can be checked with an ohmmeter. With the switch open, there should be infinite resistance. With the switch closed, there should be zero resistance. With the switch off, there should be no continuity between the terminals. With the switch on, there should be good continuity between the terminals. If the switch is activated by something mechanical and doesn't complete the circuit when it should, check the adjustment of the switch. (Some switches are not adjustable.) If the adjustment is correct, replace the switch. Another way to check a switch is to simply bypass it with a jumper wire. If the component works when the switch is jumped, a bad switch is indicated. Voltage drop across switches should also be checked. Ideally, when the switch is closed there should be no voltage drop. Any voltage drop indicates resistance and the switch should be replaced.he fan motor,the fan switch,or the coolant temp.sensor.682 questions posted
