Radiator fans not working on a 2005 dodge grand caravan SXT


Mostly, the fan relay is a cause of this problem. Check it and replace your fan relay if it needs. Also make sure that the fuse and the battery connection is in good condition. I did a quick search online and if you do need to replace your radiator this site looks like it has cheap prices, free shipping and great reviews http://www.buyautoparts.com/part/replacement-radiator/

1998 Dodge 3.3ltr grand caravan overheats.I have repaced water pump,Thermostat,Had cracked head and replaced both of them with new ones,Replaces fans,replaced fan relay,All hoses,Radiator.When i start...


You would need to figure out if it is a cooling problem or something producing extra heat in the engine.
Is the radiator fan pulling enough air thru the condenser and radiator ?
Is the fan coming on and also when the ac is on and when the engine reaches 220 degrees ?
Is it possible the exhaust has a restriction somewhere ?

Our 1999 dodge grand caravan radiator fans don't come on and our van overheats. we have to hot wire the fans directly to the battery. We also need to know where the relay is


it may be the temperature sensor that activates the fans is faulty & needs to be replaced or it could be a loose wire or connection check the wiring & connectors......hope this helps......cheers.

Radiator fans will not come on- 2000 Dodge Grand Caravan


On the 3.8 6cyl it's near the thermostat housing, it looks like a spark plug that has 2 wires going to it.

3.3 6cyl may be similiarly located near the thermostat housing.

Autozone.com has troublshooting section and repair section online that may show the exact location

Hope this helps.

I took my 99 dodge grand caravan to advanced auto and got a computer readout of p1491 as the error code. is this important and is this expensive?


P1491 is Radiator Fan Control Relay Circuit. MEANING: An open or shorted condition detected in the low speed radiator fan control circuit.
Some questions for you:
1. Is your Caravan overheating?
2. Is your Caravan water temperature spiking going past the midway point on the Temp Gauge before the radiator is engaged?
3. Is your Rad Fan coming-on and then turning off and back-on in a very short period of time (like under a minute?
If all of these are "No" then do not worry about it.

99 dodge grand caravan a/c not working.compressor cluch working,fans don't come on lines hot down at compressor


Cooling fans must work with a/c on.With a/c turned on check voltage at fan motor plug.If no voltage have to back trace to fuse for fans or relay's,but I have replaced a few fan module's for this problem.

Radiator fans wont turn on to cool radiator for 2001 dodge grand caravan


To check it run wires from the positive and negative battey posts directly to the fan motor connector. If it doesn’t run the fan motor is defective.
