Hi, the other day the radiator fan on my 3.8 l grand caravan did not turn off when I turned the car off. Unfortunately, I was at work and the battery died before I realized what was happening. Has not happened again. What do you think?

 

Welcome to DF
There was a TSB or recall to replace the fan relay and flash the PCM.The relay is on the driver side frame rail, under the air filter box.
