Look at where the AC condenser sits in relation to the radiator. On the older Caravans there was one fan for the radiator and one for the AC condenser, and they sat side by side. They each had a separate job to do.
If you find the AC condenser sits right in front of the radiator, and one fan is in front and one in back, those would be a low-speed fan and a high-speed fan. That is much less common. Chrysler favored a single, multi-speed fan because it low speeds those were very quiet.
You need to list the engine size because the cooling systems will be different, particularly between the four-cylinder engines and the V-6s.
You CAN drive with no fans at highway speed because natural air flow is more than sufficient and the fans wouldn't turn on anyway. It's in the city and stop-and-go traffic where they're needed. The problem is if you unplug a fan motor or relay, that will be detected by the Engine Computer which will set a diagnostic fault code. The first concern is when a fault code is set, when anything related to it is used for reference in running other tests, those tests might be suspended. That means other problems that occur might go undetected. Also, a fault code that relates to something that COULD adversely affect emissions will turn on the Check Engine light. With that light already on, you'll never know if another problem gets detected. Sometimes those are very minor problems that can turn expensive if they're ignored. For that reason, I don't like to recommend unplugging things. If you have to, I'd unplug the fan motor and not the fuse or relay. I can't remember for sure if that will turn on the Check Engine light.
