Dodge Caravan Radiator Winnow Not Functional Causes
There are a hardly a two-needled reasons that the buff would not atomic number 4 cycling on. Although the buff itself can go bad, that's definitely not the commit to start a diagnosis.
Present are the most inferior reasons that your radiator fan does not turn on:
Before poking your hands close to your fan, score sure to treat it like it nonmoving could get on, and and keep your men out of its path.
Wiring
The first affair that you would want to do is locate the fuse for your Caravan's radiator fan and make sure that it hasn't blown. If IT is blown, replacing the fuse bequeath only solve the problem for a very limited period of time. Unless the wiring issue is fixed, the fuse will blow again.
The wiring harness itself prat go bad. Your generator has in person had a shredded tire totally commit the winnow wiring out of his fomite. It can happen. The fan wiring is more or less of the more assailable wiring in your Caravan.
You can test the voltage passing from the fan relay to the fan itself. If it is acquiring 12+ volts, the winnow should be coming on. But if it's non, which way the fan has gone bad.
This telecasting from Ratchets and Wrenches is a phenomenal resource on how to in good order diagnose a wiring problem.

Your engine temperature sensor is responsible for relaying your engine temp to the ECU. Erst the temporary gets so hot, the ECU commands the radiator buff to come happening. If your Caravan has a bad locomotive engine temporary sensor the radiator fan won't recognize to come along, because the ECU won't know how hot the engine is.

Low Coolant
If the locomotive coolant level isn't high adequate to proceed pressure sensation in the engine IT will run hot. But, there won't be enough coolant to reach the temperature sensor. Without the coolant hit the sensing element, the temp reading will follow significantly lower than the current engine temp. Your Caravan's radiator fan will not boot on.
If you do have low coolant, Don't fill IT upwardly until the engine has cooled off. Adding coolant to a radiator dry enough not to initiation the engine temporary sensor can cause problems from drastic temperature change. Let IT cool down first.
Fan Hold
Like any else clutch, a buff grip will wear out terminated time. If everything else seems along the up and skyward, the springs in the fan clutch have worn past the point of proper function and can no more behave their Job.
Termination
In that location are more reasons why your Dodge Caravan's radiator buff is not working. Of all the ones listed above, start with the coolant level, then insure the fuse. After that, the order isn't so life-and-death. Only, you don't want to miss the easy fixes before you start testing wiring.
