Question about Chrysler Town and Country
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.

Fifteen minutes! you have bigger problems than only the fans the fans are controlled by a thermo switch that is heated by the coolant, If you have no coolant the sensor cannot activate But fifteen minutes seems like you may have a headgasket problem and steam cannot heat the coolant sensor.OperationNotesThe electric cooling fan operates when the engine cooling temperature exceeds a certain value. The cooling fan on this engine is controlled by the Powertrain Control Module (PCM) . The PCM turns the cooling fan ON by grounding the coil of the cooling fan relays when certain conditions are met. When the A/C is requested, the cooling fan will also be turned ON.
Power for the cooling fan motors are supplied through Maxifuses(R). The cooling fan relays are energized when current flows from the fuses in the Underhood Accessory Wiring Junction Block, and through the relay coils to ground through the PCM. The Coolant Fan 1 Relay Control Circuit is grounded for low speed fans operation. During low speed fans operation, both fans run at a slow speed. The Coolant Fan 1 Relay Control Circuit is grounded for high speed operation. During high speed fans operation, both fans run at high speed.
IMPORTANT: When certain Diagnostic Trouble Codes (DTCs) are present, the PCM may command the cooling fans to run all the time. Perform the A Powertrain On Board Diagnostic (OBD) System Check prior to diagnosing the engine cooling fans.
For more information regarding the Charging System, refer to Charging System Description , and Charging System Circuit Description in Starting and Charging.
If a problem that involves the low speed cooling fan relay control circuit exists, DTC P0480 Cooling Fan Relay 1 Control Circuit should set. If the problem affects the high speed cooling fan relay control circuit, DTC P0481 Cooling Fan Relay 2 Control Circuit should set. A problem with the ECT sensor should set DTC P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low Voltage, DTC P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Voltage, DTC P1114 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent Low Voltage, DTC P1115 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent High Voltage. Any of these DTCs will affect cooling fan operation and should be diagnosed before using the Electric Cooling Fan Diagnosis.
For more information regarding the Cooling System refer to Engine Cooling Fan Description - Electric, and Cooling System Description in Cooling System.
Here is the electrical schematic and how it all is suppose to work,

You have air trapped in the system. If you have cold air, warm air, cold air from your heater, then it's air entrapment. Very common these days. Go to a shop that uses vacuum method to refill cooling system & that will purge air.
Otherwise, you can try. Park uphill. cold engine - fill radiator to top with 50/50 mix of antifreeze. leave cap on but loose. fill reservior to 3/4 full. Turn heater to hot to allow coolant to flow through heater core. start engine, run at 1500 rpms until thermostat opens and upper hose is hot. tighten cap and let it cool down. after cool check level of reservoir. fill to top line on reservoir. it should **** coolant back into radiator as it cools down.
repeat if still an issue.

Testimonial: "Thank you. That is exactly what it was and doing a pressure test we discovered the air was coming in through a microscopic crack in the radiator."
the relay is located in the power distribution box under the hood the relay will be a square black or gray cube just pull out and make sure you rerplace it with the same type relay. refer to your owners manual for any questions regarding the fuses and relays

Testimonial: "He knew exactly where to find a part while the experts at Auto Zone, O'reillys, & a local Chrysler dealer could not tell me. I am pleased & impressed."
this van has a solid state relay unit to control the fan, when it dies it just allows the fans to run. this relay is located behind drivers headlight, attached to the bumper towards the grill. It will either be bolted on or riveted on. There will be big fins on it to keep it cool. When you change this unit you have to mount it for it to work right (zip ties are no good) seen that before.
