Where is the fan relay on 1999 aurora located

In the engine compartment fuse block. Look at positions 7 and 8. There should be a diagram under the lid.

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:

• Number one
• Number three
• Number two

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.

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.

It's on the right front corner of the engine comp. Then there is the one under the rear seat and the one on the drivers on the bottom of the door pillar (a-pillar).

Hope that helps

there should be a fuse located on fuse panel for heater motor( 30 A Green)....after you check fuse other possibilities are bad fan motor...bad heater resistor block.....bad relay...the resistor blocks are very common problems

SOUND LIKE COOLANT FAN NOT COMING ON.MOST TIME THE COOLANT TEMPERATURE SENSOR HAS A OPEN CIRCUIT IN.WHICH CAUSE NO COOLANT FAN OPERATION.

I would first check out the fuse (if there is one listed). If that is good, replace the relay. These are both located in the fuse bank in the engine bay. Fuse and relay discriptions should be on the underside of the cover.

there is no resistor but it does have a digital fan control module located under the hood above the fan motor in the heater box. you will need to remove the plastic cover again the firewall.and the the module will be under the relays.

Behind the " gooseneck".follow the top rad hose and you will see a green wire attached to the fitting. this is for the gauge/idiot light. If you are looking for the fan control sensor. It is, I beleive, computer controled. If you are not seeing a warning light or bad readings on your gauges, I would suspect the cooling fan relay.

The heated seats have relays that run them. Not quite sure where they are located but. That noise is the relay clicking on and off. They are actually pretty loud. Look for faulty connections to and from the relay and check battery power to both sides of the relay.

The starter is located under the intake manifold.
