cooling fans not coming on...problem solved

I recently have been seeing trends with overheating cause of the cooling fans being inop for the last month. Mine has been doing this since I owned the car, so last year I made a switch to turn them on manually.
Just today I was reading some of the trends and many replied to switch the relays for the fog lights and the cooling fans, I did that. I also seen to replace the fuses even though they might look to be good, I did that as well. Finally someone stated to pull the pcm bat fuse and replace it as well.
I dont know which one fix it, but it worked, got the car up to half way between 210 and 240 and they came on. I also had a new coolant temp sensor at the waterpump put in.

This site just amazes me
