Check fan relay
My 1999 Grand Cherokee just started this today. My first thought is that the fan relay is stuck in the "on" position.
There is no time frame for replacing a relay. You will only need to replace one if it goes bad. Then you can test it by replacing it with a different relay from a different plug that is the same type, and that you check to see what that one will affect. hope this helps.
