All of a sudden my radiator cooler fans stay on. Neighbors knock on the door to see if I knew. The only way to get them to shut off is to disconnect the battery. How do I solve this problem.

 

The cooler fans have 2 fuses located in the engine compartment LHS front fuse box. Fuse #11 and Fuse #17.

I had a similar problem in the past where the cooler fans continued to run long after turning off the ignition. I removed the fuses and replaced and it fixed the problem.

Please note the the fans are designed to continue running for a period of time after turning off the ignition, this is normal
I hope this helps.
