Replaced relay, but both electric fans won't come on

To clarify, the compressor and fan will run in defrost mode. The compressor and fan runs to dry out the air blowing onto the windshield.
Now if the condenser fan runs in "heat" you may have a problem with the fan relay or the main controller.

i beleive you did more than that.? you,ll probably find all have a common earth , chech and remove it , clean with a wire brush and replace, also chance the fuse you removed and replacer reguardless of it,s appearence , ensure its put back in the correct location,peter.

I would look to the electrical side of the fan operation. You have three basic components to the cooling fan operation...the fan switch, the fan relay, and the fan motor. You need to determine what part of the system is not working. If you can run a 12V jumper wire to the motor and it works you know it must be either the switch or the relay. if you jump out the switch and the fan runs, you know it must be the switch.

sounds like the relay is stuck on

Sounds like maybe the relay is not working. Posible causes might be a bad relay, no power to the ralay, a grounded wire from relay to the PCM (computer) ect...

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

There should be an electric fan in front of your radiator. Check to make sure that it turns on whenever the air conditioning compressor kicks on, or whenever the car is too hot. If not, the electric fan may have failed, but the most common failure point is the relay for the electric fan.
There may be a temperature sensor in the end-tank on the radiator with a three wire plug. That is supposed to turn on the electric fan when the engine gets too hot. If you short the two hot wires to the brown ground wire with the key turned on, you can test to see if the relays work for the high and low speed settings. If the contacts have burned away in the relay, you will hear it click but the fan won't turn on. The sound will help you find the relay.

Hi belindacavey,

I have seen a few problems with the cooling fan on Land Rovers. Usually the relay portion of the fan fails. For a while Land Rover had fans on back-order because so many where failing. I would recommend having the fan/relay checked. FYI the relay module and the fan are usually one assembly.

How did you determine that the sensor failed. Did the check engine light come on? When you say that the fan won't turn, do you mean that it won't turn on and run or that you can't physically turn it by hand. To determine this, disconnect the electrical connector to the fan and try to turn it by hand. It should turn easily. If it doesn't then it must be replaced. If it does then reconnect the electrical connector to the fan and try to operate it by disconnecting the temperature sensor lead and placing a jumper wire between the terminals of the harness. turn the AC control to AC/MAX and turn the ignition key to on. If the fan runs then the problem is the sensor. If it doesn't then check the fan control relay and any related fuses. WARNING : Use extreme caution when testing the fan circuit. Never attempt to turn the fan with the electrical connector in place. The fan can operate at any time even if the engine is off.

It is most likely the fan relay is sticking and allowing the fan to run on, the relay is plugged into the fuse/relay box on the drivers side of the engine compartment.
