so like the title says I've been having this issue ever since having to put back the 5sfe motor into my car. Both radiator and A/C fan start to run the moment i turn the key to the "on" position. i tried unpluging both coolant temp sensors but they continue to run, my relays for the fans are working correctly so at this point im confused and exhuasted, the only thing i can think of is the ecu took a dump on me and is telling the fans to stay on all the time BUT i dont have another ecu to swap it with and i dont want to spend the money to do so and i end up being wrong. so has anyone else ran into this problem or have any suggestions for me. i really wanna fix this cause im sure its the reason my car runs like **** in cold start and takes forever to warm up properly.
-------------------- I only want to be faster than the guy next to me.

If the fan's power is disconnected, then yes it won't run. If the water temperature fan switch is disconnected, or faulty, the fan will run all the time -- it's Toyota redundency.
