How do you replace the relay on the cooling fan---fan is not working and fuse is good

Hello. Your car's cooling fan relays are somewhere in the fusebox/relay box. Also, your car has a 'fan switch' on the thermostat housing. If the 'fan switch' is in operable, the cooling fans won't work. It can be the thermostat housing seal/gasket. Good luck and keep me informed; if you want to.

there is 2 fuses that you have to check
one will be in the big fuse assembly in the engine bay, the other probably in the fuse assembly in the cab
If they prove ok then it is possible that the coolant temperature SENSOR is faulty and needs replacing
don't confuse it with the temperature sender which operates the temp gauge.

Hi Naomi , there is a lot involved in the control of the cooling fans on your vehicle ! There are three fuse's , three relays an a fan control unit !
1. radiator fan main relay , located in underhood relay box A
2.condenser fan relay , located in underhood relay box A
3.radiator fan relay , located in underhood relay box C
4.Cooling fan fuse # 47 20amp. underhood fuse / relay box
5.condenser fan fuse # 50 20amp in underhood fuse / relay box.
Any one of these could cause them to not work, rather then just replacing parts an wasting money you should take it to the repair shop !

the fan have a relay, turn your AC on and check to see if it comes on your fan have 2 speed one is for temp and the other for AC.

Well the code is for the circuit - the computer commands the relay to turn the fan on and it doesn't happen.
The computer provides the ground for the relay.
If you have replaced the relay and the fan and the fuse still blows, I would look for a problem in the harness between the fuse box and the fan, including the ground circuit for the fan.
The fuse for the cooling fan is usually a 30amp marked "cooling fan" in the fuse box in the engine compartment.
Do you know what the 25amp fuse that is blowing is for ?

If the fan not turning on when car engine getting hot,then car will notice overheating.Click this link below for troubleshooting:---http://technoanswers.blogspot.in/2012/02/car-running-hot.html--------To know how engine cooling system works ,click the link below :----Engine cooling components working?

CHECK MODE RELAY IF BOTH RELAYS GOOD YOU CAN CHECK RELAY BY REMOVING IT FROM FUSE BOX HOOK RELAY TERMINAL 85 TO BATTERY POSITIVE AND GROUND TERMINAL 86 IF CLICKS RELAY GOOD. IF RELAY GETTING POWER GOOD AND THE 30 AMP COOLING FAN FUSE OKAY.EITHER THERE IS A SHORT IN COOLING FAN WIRING OR THE PCM HAS FAILED.THE PCM HAS LOST OR COMMAND RUN CIRCUIT IN PCM SHORTED OUT DUE TO PCM FAILURE.LET DEALERSHIP OR GARAGE USE DIAGNOSTIC EQUIPMENT TO ACTIVATE THE PCM SEE IF IT HAS FAILED.DONT SPEND MONEY ON NEW PCM COULD BE SHORT IN THE WIRING CIRCUIT

1. check the cooling fan fuses
2. supply battery voltage directly to the fan assembly plug
a. if fan is good
locate and test/replace cooling fan relay
b. if bad
replace cooling fan assembly
if still is not working check continuity cooling fan system circuit/wiring

CHECK COOLING FAN FUSE AND RELAY.IF BOTH GOOD SCAN CAR TO CHECK COOLANT TEMPERATURE SENSOR FAULT CODE.THE PCM AND COOLANT TEMP. SENSOR IS WHAT CAUSE FAN TO RUN AT CERTAIN TEMPERATURE.IF ALL IS GOOD.HOT WIRE COOLING FAN USING JUMPER WIRES TO BATTERY.IF FAN DONT RUN REPLACE FAN MOTOR.IF FAN RUNS YOU HAVE SHORT OR BROKE WIRE IN THE COOLING FAN ELECTRICAL CONNECTOR.

there is a relay panel under the hood with your engine cooling fan relay inside, a 12 dollar part, sounds to me like this relay may need to be replaced. There will be a diagram in your owners manual telling you exactly where it is located in your car. It should be noted that this relay has to be activated before the current reaches any fuse inside the cars fuse panel so your fan fuses can all be good but if the relay is not working the engine cooling fans will not come on. Be careful of dealerships I had one tell me it was a 3000 dollar wiring problem when it was only the relay.
