Why won't Rad fan run if fan motor, fan relay, temp sender all okay?

check terminals on the ECM
the circuit is when the coolant temp sensor ( not the gauge sender) reaches a predetermined setting , power is supplied to the ECM which in turn activates the fan relay and switches on the fan
there are normally 2 fuses in the circuit
the gauge sender is normally a single wire unit and the sensor unit has 4 wires to it

Radiator fans don`t work on town and country van causing engine to overheat

The radiator fan relay is located behind the grill on the driver's side of the vehicle. There is no relay in the distribution box. There is a 40 amp fusible link, however, in that box.
The relay (behind the grill) works in conjunction with the coolant temperature sensor, the A/C high pressure switch, the transmission temperature sender and the PCM. This relay will run the fans from 30% to 99% of full speed based on the signal coming from the PCM. This is all according to the official Chrysler shop manuals that I have for my 2005 Town and Country van.

It would help to know specifically what van.
But in general, there would also need to be some kind of temp sensors. If what ever van you have just uses the ECM to turn the fans on and off then it may be a bad computer temp sensor.
The ECM also needs to send a ground signal to the relay when it gets the right temp readings. You can also check for power at the relays.
There could also be a temp sender elsewhere like in the radiator or cylinder head that will supply a ground when the heat is up.

You can get free diagrams from in the repair section. These should show you everything in the circuit and give an idea of what to check.
You will just need to register, which is also free, and enter the specific vehicle.

Cooling fan will not come on. If i unplug the coolant temp. sender the fans will engauge. Have also changed the relay. Tempeture gauge apears to be work on the display in the van. Not sure where to go now.

There is a soild state relay with three or four wires mounted to the drivers side frame rail, it flat and has an aluminum heatsink base, this is most likely your problem

u should check for a faulty thermostat first, they are only a few quid and easily replaced. if no change ur most likely faults are a blocked radiator or faulty water pump. u dont sayhow old ur van is but after the thermostat go to the radiator, when its hot check the bottom of the rad to make sure its hot, also brown water means u need to bback flush ur cooling system. even tho u have changed some sensors doesnt mean u got the fan switch sender, dash board sender and fan sender tend to be different sensors, so just double check.

My 2002 Jeep grand cherokee radiator fan wont come on it will come on when its been hot wired. I wanted to put a toggle switch on the inside of the truck so I wouldnt have to keep goin under the hood. or...

You need to check the temperature sending unit and the relay. Relay is below and behind the r/f headlight. Temp sender sends info to the computer that then sends ground to relay which then turns on fans.
You can use a toggle but if you forget to turn it on it may cost you an engine. If you must, I'm sure you can get a sensor and relay for an aftermarket fan and use it on yours.
If you liked my response please rate it. If you have a question or did not understand it just ask.

Cooling fan won't come on after car start to over heat. where is the relay located?

The SSFR (Solid State Fan Relay)Cooling fan relay is located on the left front inner frame just behind the radiator.

The radiator coolant fan relay is located on the inside front of the engine compartment near the left headlight assembly. You have to remove the air filter assembly, then look for a simple square relay with 4 wires running into it. It is mounted with 2 screws. It is the only relay at that location. If it has burned, you will need to replace the pigtail wiring harness.

Remove the air box beside the battery a 10 mm bolt and the relay is a four prong square box bolted on the frame with two 8mm bolts.

Hope help with this (remember rated this).

My engine light is on and it says:low speed cooling fan relay circuit failure,fan doesn't run.I can make the fan run at pigtail.I only have 1 hotwire at the lowspeed relay.What could this be?

Start with the fuse, if blown, it could cause this type of condition in some cars. The next thing is it could be the sender or sensor. This is located near the thermostat on the engine. This is basically a heat activated switch that will turn on the fan when the engine tempter reaches a pre set level. To test the sender you need to remove the sender and attach a continuity tester to it. next submerge it in hot water with a thermometer and see if it closes the circuit and at what temperature. Normal engine operating temperature use to be around 180 degrees give of take. Today engine temps vary by manufacturers so check with the dealer or on line if passable.
