How do i replace the radiator fan relay in an 05 town and country

cooling fan relay stuck in the on position its a solidstate relay and shorts to its self internaly

the radiator temperature is broken or cable to it is disconnected ?
if true they are set to run constant the fans to protect the engine from overheating. also check the relay is still seated correctly.

It should be a fairly simple R&R since the fan and shroud is bolted to the radiator support. Usually you take it out as an assembly.
If you haven't done so already, be sure and check the fuse and relay before condemning the cooling fan motor.

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.

look behind the drivers side headlite on the crossmember , it looks like a silver module , clean and check the plug , it is corroded 9 out of 10 times , just did this on my 05 t and c , hope this helps

Down by the bottom of the radiator. pass side. on the frame/rad support. You probly have to remove front splash shield to get to it. I have never had to remove or change one.

Look at the left (driverside) framerail near the radiator support. You can get to it from underneath, it has two small sheet metal screws holding it to the inner framerail. The framerail acts as a heatsink.

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

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

some cars do start up the fan when turned off after they have been driven. as long as it is not starting when the engine is cold there is nothing to worry about. the reason it took 15 mins to shut off is that with the engine not running the water is not being pumped
round the engine thus cooling faster. hope this helps
