Why is my radiator not turning on on my Dodge Grand Caravan?
I have a 2000 Dodge Grand Caravan that has 195,000 miles. My radiator fan won’t turn on and I’m stumped! The issue presented itself with a check engine light and the radiator cooling fan not turning on.
What to do if your car fan won’t turn on?
It either will go to ground and turn on the fans or supply power to the coil and turn them on. If so then try placing a ground connection on the Lt grn/dk blu wire that goes to the ECU and verify that the fans turn on. If they work ok then the ECU isn’t turning the fans on for some reason.
How can I tell if my radiator fan is still running?
To check an electric radiator fan, start the car and let it get up to the temperature where the fan normally kicks on. Use the volt meter to test if there is power to the wires. Connect one end of the volt meter to a ground and the other end to the electrical connection on the fan.
Can a radiator fan cause the engine to heat but not the engine?
If you see the engine heating but the radiator fan isn’t, the fan wires could be the culprit. Simply unplug both the wires, negative as well as positive. The standard direct current they must put out is 12v (approx.). Take a voltmeter and check for the presence of current. If there is none in either or both, you will need to replace it.
What should the current be on a radiator fan?
Start by unplugging the wires. There will be two wires of positive and negative feed. They should be putting out around 12 volts of direct current. Use a voltmeter to check that there is current present. If there is not, you need to check both the wires and the fan relay to see if replacement is required. The fan relay will be under the hood.
