Is the temp sensour located on the tramission. We found 2 possibility on the 2005 town and country 3.3 chysler. And approx. size r the wires

Did you mean thermostat in Engine Cooling Water

Most likely it is the switch, not the motor or relay.

if this is the service light, you could try 1.Disconnect battery for couple of minutes. 2. on trip meter button hold in and turn ignition on wait till light goes out in possibly 10-15 seconds

possible bad injector - recomend have injector checked and or do compression test on cylinder # 2

There are sensors and relays for the fan [s] , sounds like you have a defective one.

Go to a public library, and get access at ALLDATA repair on line for free. Select the year, make, model of your car, and navigate.
There you will get the explanation and the picture of the engine with temp sensor, which you can print for $0.1 only. I hope this will help.

What size Engine?
The Number 4 fuel injector goes to Cylinder #4.
On 3.3L and 3.8L it should be the Front Middle Cylinder.
If you are not sure where Cylinder #4 is. Look on your Electronic Ingition Coil = Distributor. It has small numbers on them #1 thru #6. The numbers are small and black, but they are there. Follow that #4 wire to Cylinder #4. Fuel Injector #4 should be right over the top of that Cylinder. Usually the Cylinders themselves have numbers on them on the engine block, but it is easier for use to use the Ignition Coil as a reference.
Cylinders Numbers should be:
1 - 3 - 5 Rear
2 - 4 - 6 Front
Ignition Coil should be:
6 - 3 Rear
4 - 1 Middle
2 - 5

There are no onboard diagnostics on a Chrysler T&C. You will have to connect an external reader. You can purchase the diagnostic reader or take it to a repair shop and ask them to do it.

Can you hear the fuel pump run when you cycle the key?

do you mean they are sticking?
