Why would a 99 Chrysler Concorde radiator fan quit working all of a sudden And 2 weeks prior the ac stopped working?

I have a 1999 300M, and funny to say, the same thing happened. two weeks ago my A/C stopped working, and now the radiator fans are messing up. I checked the fuse box and both hi and low radiator fanfuses were burned. I am going to take the car to be checked this week. I'll ket you know how it goes.
