I have done a lot of research on this problem. There was a recall issued for certain chrysler products with fan control relay problems. I am looking for the recall info but I have only located one for a PT cruser. You need to go to a dealer and let them look up your vin number and check for a recall notice.
I did find out that the relays must be replaced with a solid state circuit relay from the dealer and both relays must be replaced. The code will also set is the fan has been replaced with an after market fan.
Chrysler and Jeep have been suffering from this problem through the mid and late 90's.
I hope this helps Good luck
