New to this forum so sorry if this has been discussed before but i had an issue this evening when i got home from work. I shut off the engine and the radiator fan continued running. This is after driving about 1.5 miles at about 30 mph top speed. The radiator didnt even have time to get hot! Popped the hood and let it sit for about 2 or 3 minutes before i finally just unplugged the fan. Plugged it back in a few seconds later and fan starts right back up. Looks like maybe switch is stuck????? Anybody seen this before? Thanks!

pull off the negative battery terminal and the J19 fuse for a few minutes. That seems to "fix" a lot of problems like this with the JK. Put the fuse back in while the battery is disconnected. reconnect the cable and fire it up.

if that trick doesn't work, and you're under warranty, go to the dealership. the relay is probably sticking and needs replaced. if you are out of warranty, simply try replacing the relay.
