2003 Dodge Town and Country Van, 3.8 V6. Where is the engine cooling fan relay located? I replaced the blown 40 amp fuse, tested both fans, the are OK. Need to locate relay!

Check the fuse and relay for the Front Blower. You can swap front the back to test the relay.

code 35-Radiator fan control relay circuit-open or short detected in the low speed radiator fan relay control circuit.

yes there is a fuse and it should be behind a panel in the lower dash near the drivers area..the fan is located under the hood way back up behind the engine on the passengers side and kind of hard to reach..good luck

There are many things that can cause your radiator fans to not get power. However, the most common cause is the fan control module. Some people call it a "fan control relay", (including many aftermarket parts retailers) but it is actually a solid state control module, not a relay.

Check for power in and out of the module. It is best if you have access to a scan tool that has system test capabilities so you can command the fans to turn on with the computer. Otherwise, you will have to get your engine really hot and see if the power is being sent from the control module to the fan motors.

The fan control module is located on the inside of the left frame rail (driver's side) just behind the radiator. You will have to get under the vehicle to see it. It looks like the picture below.

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 is located under the hood between the radiator and the front grill. You will have to remove the platic cover between the radiator and grill to see it.

relay located in the fuse box located under the hood, fuse/relay box is generally on L side of engine compartment.......fan relay should be marked under the cover...testing....try a new relay....they are cheap.
yet use a chrystler part!

Probely a bad relay in the fuse box on the driver side. Theres a map under the fuse box cover to find the RAD FAN relay. There the same as other relays that the van uses. Pull the fan relay & replace with same number thats on the top. Theres also a 40 amp for the fans.

fuse/relay center underhood possibly corroded internally..lots of issues with these fuse blocks

Hi
If your radiator cooling fans are not operating when you are at normal temperature, I would suspect you have an electrical problem with the feed to the fans.
Possibly the thermal switch on the cooling system, or a fuse has blown.
I hope this is of help.
Good Luck !
John.
