HELP!!! Coolant Fan Problems!!! I am no wiring guru by ANY means so I need help here because I can not find an answer that tells me anything. I have looked at wiring diagrams and all but I cant figure this out...
The Issue:
My cooling fans do not turn on at all. I have an SLP Fan Switch but when I hit the switch they DO NOT come on. My tune is set up for my fans to turn on at 180/190 degrees but when driving my temp gets to 210 when sitting still...cools off when I get moving again. I get out and pop the hood and at 210 the fans are not on. The coolant temp gauge works and according to my laptop it is accurate.
What I have done:
According to what I have read I have began diagnosing what it could be. I get power to the fan fuse.
I get power to the #1 socket of the Coolant Fan #1 and #2 Relays at all times. I DO NOT get power to the #1 socket of the Coolant Fan #3 Relay at all. With the key on I am SUPPOSED to get power to the #5 sockets however I do not get power to them with the key on for ANY of the sockets.
Anyone know what would cause this and where I need to look? I am horrible with wiring...Thanks!

I would check the ground wire that is right on the drivers side frame rail. Mine was broken off and none of my fans would come on and it would blow the 10A fuse every time. The relays that route the power for the electric fans are on the fuseable links. They are always hot.
