Cooling fans not running

My cooling fans dont seem to be working. I went to get my 02 smoged today and as it sat outside the smog shot it overheated and leaked fluid all over the place. Once i started moving it cooled right back down and started to over heat again in my driveway. i poped the hood and neither of the two fans was running. I have looked in the haynes mannaul but i cant read the diagrams to find the fan relays. the 40A fuse is fine but i dont know what relays to replace befor i go buy new sencers or a new fan that i dont need.

i'm not a buff on this subject so I searched a little for you and came up with this --> http://www.autozone.com/az/cds/en_us/0900823d/80/04/ae/a7/0900823d8004aea7/repairInfoPages.htm

i'm directing you more towards the test section, but an overview of the system and an understanding of how it works always helps with not just finding the problem but also fixing it.
the troubleshooting here doesn't seem to difficult so i'm sure you can manage it. if this doesn't help let me know.

Thank you very much. Tested the sencer and it checked out, im not sure what happend but just messing with it fixed the problem my fans are working now.
