Jeep Cherokee XJ Forum

My check engine light came on in my 2000 Grand Cherokee Laredo yesterday.  I went online to find the code and it came back as the relay for the electric fan.  I've had this and the fan replaced on my truck at least 3 times now.  This time I want to do it myself if I can instead of paying the outrageous cost.  How simple or hard is this to do?  I hear you have to go in behind the passenger side headlight.  Then what?  Thanks for your help.
