I assume they did not work. Have the Thermal Control sensor replace. It turns on the fans. It is located at the engine rear near the thermostat intake manifold. It is a small gadget with a plug which you can remove.It costs about 12 dollars. Be careful not to break the thread when you remove it. Go slow, it may be a little hard to remove.Get some WD40 and spray some on the thread before removing.

Engine fan


test the fan for proper function if its burnt anything you do will not make it work so jump power wires to the fan to see if it works you also have a temp sensor that might make the fan work as well if its defective does the temp in the car go up if you have a guage on the dash or a light comes on hot so 1- fuse ok 2- relay is a good working 3- connector at fan ok 4- fan motor working by jumping wires easy to follow diagnostics

Unplug the fan on sensor. It should have one green wire and one black wire. Use a paper clip and jump the two wires. Turn the key to the run position, the engine does not need to be running. Does the fan come on? If not check the green wire for 12 volts and the black wire for ground. If there is no ground than run a new ground wire. If the is no power check the heater/air conditioning fuse in the under dash fuse block. If there is power and ground make sure both the cooling fan fuses are good and both the cooling fan relays are good.

2002 jeep liberty p1491


Hi there:

P1491 is for the cooling fan relay control circuit as you've found already.Start by checking the fuse for the fan relay. Its in the box under the hood, a 40 amp fuse.If you've got a couple jumper wires, you can unplug the fan connector and carefully jump the fan to see if it works. The fan connector is on the right side of the back of the fan shroud. Unplug it and jump the black wire to ground and the green to positive. You've got to be very careful doing this though-you are in very tight quarters, its not hard for your jumper wires to touch each other in the connector and short together, and if you use small diameter jumper wires they will get hot quickly when the fan comes on.If the fan doesn't come on when you jump it, or if it runs slow or sounds bad, you've got a bad motor and will need to replace the fan assembly. One thing that does happen somewhat often, is a bad fan motor will burn up the relay. If the fan motor is drawing too much current it will overload the relay and burn it up. This is why its so important that if the fan motor runs slow or makes noise that you replace it, or you may end up burning up relays frequently.If the fan runs and the fuse is good, its very likely you just need a fan relay. This is a pulse width modulated relay, not the on/off clicker type you'd find in the fuse box. This unit is capable of infinite speed control. It gets very hot in operation, so its mounted to the body sheet metal to allow heat to dissipate through the sheet metal. The relay is mounted under the right headlamp held down with two 8mm screws. To get to it you have to remove the front bumper cover and headlamp bracketry to access the relay. These relays are pretty common.

Hope helps.

The fan will not run i have replace the temp swech and the relay and the fan and thesen unet.if i cross wire the relay it will runs all the time what can it be help


F you have battery power and ignition power at the relay, and the circuit is good from the relay to the fan. then the fan is turned on bt the high pressure A/C switch or the ECU. If the circuit (ground ) to the ECU is good you probably have a bad ECU.

The ECU drives a relay which in turn drives the fan. Trace the fan wiring back to the relay and check the plug connection. Does the fan turn freely by hand? If not, replace it. The fan needs a solid ground connection as well as power from the relay.

Radiator fan


You should check the 30 amp "RDI" fuse and the 7.5 ECU-IG fuse. Both fuses are critical to the operation of the fan system. The RDI fuse sends power to the fan #1 relay. The A/C amplifier turns on power to the fan #1 relay, this is why your fan works on A/C.

Now, with no cooling fan under "normal conditions" (A/C off), you need to have a good fan #2 relay, and a good water temp switch. This switch is on the engine, near the thermostat housing (I think); with a single plug, with a white with a blue trace wire going to it. Remove this wire from the sender, and jump it to ground (anywhere on the metal of the engine) with the key on (engine OFF). If the fan starts, you need a new water temp sending unit. If not, then consider a new fan #2 relay. This system is pretty simple.
