Nope. Engine Computer and fan relay which is another computer module. What's the problem?

Been having a issue with the body control module not sure if cooling fan is working havnt had time to check it control module was causing lights to come on and stay on when we removed the module for replacement there was quite a bit of debris in and on the module (like rats or a bird had built a nest)blew it out and cleaned the contacts reinstalled it and is working but now the temp gauge is showing a little warm I know better than to trust the dash gauges but none the less with all the problems with the body control I couldnt remember if it was tied in with the cooling system

Got dizzy reading your description. You need some punctuation in there, otherwise it can be read at least three different ways. If you're asking about the radiator fan, find the coolant temperature sensor near the thermostat housing and unplug it while the engine is running. That's the two-wire sensor. If you still have a single-wire sensor, that's for the gauge. About one second after you unplug the sensor for the Engine Computer the fan should turn on. If it does not, suspect the fan relay first. You can command it to turn on if you have the Chrysler DRB3 scanner, otherwise you'll just have to plug in a different one to try it. Be aware it will get hot enough to burn your hand if it is not bolted to the body sheet metal. It lives half way down on the left side of the radiator, bolted to the support. If the fan does turn on, the system is working. By unplugging the coolant sensor the Check Engine light will turn on and a diagnostic fault code will be set in the Engine Computer. The light will go off when the sensor is reconnected and the engine is restarted, and the code will erase automatically after 50 engine starts.
