3sgte electrical problem Options

[SoDo]

My celica currently has an electrical issue. Its a 3sgte swap. My radiator fans wont turn on, and intercooler pump is not running. Also the cabin fan does not work at all. Any thoughts of what this could be? Ive checked fuses and relays with no luck. Any help much appreciated!!

Thanks for the reply!! I replaced the main engine relay and still no luck. The relay is working. I have 14v there and i can hear the relay click. I have no power to the fan relay 2 and ac comp relay. Fan relay 3 has power. Ill have to do some more investigating when i have more time.

I had the same issue. You need to pull the relay out and actually test that it has continuity when it clicks. Mine was clicking but it was not carrying continuity where is should have. Hearing the relay click when you provide voltage is only half of the test. From what you are explaining to me if it is not the relay it may be your CDS fan fuse. Here is another wiring diagram of the AC system.

With those 2 wiring diagrams you should be able to track down your problem with a multimeter.
