The inexperienced relay (the one the fellow is looking a "condensator" rofl) is the radiator cooling fan relay (eight) and the gray relay on the pinnacle proper is the engine fundamental relay (7). Please publish your experiences here after trying this diagnostic system in addition to any additional findings, so others can examine.

I have a 1999 toyota corolla and after i flip the ignition switch on the motor fan activates with out the engine being on. The engine is cold and everything. I have researched and observed out which relay switches are for each fan and replaced them, i have replaced the engine coolant sensor next to the thermostat, and i have replaced the pc. Granted all alternative parts had been used. Relays were taken from a junk yard however had 6 general relays of the same numbers, and a pair of sensors. I am playing off of the chances that there's no manner that all relays and sensors are awful, and the laptop i ordered become used as properly. I do not agree with its the laptop however desired to attempt. The automobile does now not overheat or have another malfunctions. My most effective concern is that the fan may also ultimately burn out from constantly running, and that its something that i want to recognize what is inaccurate with it. Do you have  any idea what it is able to be?.

If the cooling fan transfer seems to be caught within the off position, but then you definately degree a quick circuit (0-10 ohms) among the cooling fan switch terminal and the engine block (indicating the cooling fan transfer is closed), then there might be a fault (open) within the wiring harness. With the ignition off, measure the resistance between the cooling fan transfer receptacle at the harness (you will need to unplug it to accomplish that) and the cooling fan relay coil socket. One of the coil socket receptacle contacts must be related at once to the cooling fan transfer receptacle at the harness. Eliminate the cooling fan relay, then measure between touch 2 on object eight within the drawing and wire l or wire l/b on object 10. (Should be zero-ten ohms). If no longer, the wiring harness has an open among the ones points. Considering you have got already swapped relays and switches, this is probably the case. The most in all likelihood failure factor is the give up of the harness that connects to the cooling fan transfer (item 10) at or above the cooling fan switch receptacle, seeing that this receptacle is on the switch (object 10) that is at the motor and vibrates with the motor, that could fatigue the cord or the crimp connection at the receptacle. You can try cutting the receptacle off of every other vehicle as a ways up the harness as feasible (so that you have the cooling fan switch receptacle at the end of say, 1.Five feet of wire), doing the same to your car, and splicing in the "new one" (with both solder and electrical tape, for sure) at the point in which you narrow off the old one. Allow us to understand what happens!!!!.

Anyone ought to have wired you fan instantly to the battery so whilst the automobile is grew to become at the fan should come on. They could have finished this due to the fact perhaps the opposite fan is broken (my corolla has two fanatics). Also you do know that the plug that connects as much as there thermostat housing if not connected will flip your fan on all the time this is a protection degree just incase the thermostat locks closed.
