ive got an 06 5.3 silverado.. i noticed the other day about 5-10 seconds after the initial start up the cooling fans kick on, and after riding the truck 30mins and stopping 45 mins and stopping and so forth, the fans r still running and to the best of my knowledge never kicked off. they run a 160 180 190 no matter the temperature.. i can cut the truck off, start it back and once again the fans continue to run, and i forgot to mention the defrost nor a/c was on.. i dont know if it could be a relay, sensor, and what, and im not sure where the relays and stuff r located to check them, and the truck isnt throwing and codes or anything.. thanks alot for the help guys..

I assume you are speaking of the stock factory e-fans, correct?

you might want to check if you are throwing a code. This would cause the fans to come on.

so sorry for the late reply, and yes im talking about the factory electric fans.. they come on right about 5 secs or so after start up and run consecutivley.. but the engine is not throwing and lights nor codes.. and i cant find where the fan relays are located.. they arent in the fuse block in the truck or in the fuse block under the hood where the a/c comp relay starer relay and all the fog lamp relays etc r located.. ttt

They are right next to them, under that corner support bracket. If your fans are coming on right after start-up, you are throwing a code of some type. Following pic provided from Bimmer Tech:


While your at it, could you pull that fan relay/fuse block out and take a picture of how it fits/snaps in there? I'm looking at getting it to put in my '02 and want to know if it will fit with what I have:
