Where is the cooling fan relay at on a 2000 avalon

Which one ? your van has three cooling fan relays an two fans ! The relays are located in the under hood fuse box # 9, 10 , 12 ! Relay Driven Dual Cooling Fan Diagnostics

most likely a bad fan motor or an open circuit.

did you first spin the fans by hand to see if they move freely?

Check the cooling fan relays,and the fuses,also if the thermostat is stuck,the coolant sensor will not sense the hot coolant,and will not activate the relay that turns the cooling fans on,also,if the coolant is low,or has air in the system it will do this also.

It sounds like your DRL RELAY/Headlight relay. I had this happen with a 2000.

Please rate me if this helps You.

Here is some info that I hope is helpful to you.

-disconnect battery- Then remove the wire with pin attached and tape to the harness. (consider just cut and tape the wire) -check operation- [except the 2000 MY-Avalon, additionally you need to ground the wire at the module end of the cut wire]

b/c u don 't have one u have c/opn relay ( circuit open relay ) that controls the fuel pump. which is located under hood fuse box a long the driver fender. good luck

the cooling fan relay is not in the fuse box.

it is a solid state relay bolted to the radiator core support just behind the bumper

On the thermostat housing,the repair guide I see shows two one on top of the housing(controls the left fan) and one to the side(for the right fan)but this could also be caused by the cooling fan relay.

I have the original owners manual, and it says that there is a fuse (No 16) and a relay (No 10) for the blower motor. I've same troubleshooting right now. If you wants send me a email to [email protected] to send you a scan imagen of the fuses diagrams.
