Top Toyota Mark X Electrical Wiring Diagram Collections - Someone may want to have stressed out you fan straight to the battery so when the car is became on the fan should come on. They may have accomplished this because perhaps the opposite fan is broken (my corolla has two fanatics). Also you do understand that the plug that connects up to there thermostat housing if no longer linked will flip your fan on all of the time that is a safety degree just incase the thermostat locks closed.
If the cooling fan transfer seems to be stuck in the off position, however then you definitely measure a short circuit (zero-10 ohms) between the cooling fan switch terminal and the engine block (indicating the cooling fan transfer is closed), then there might be a fault (open) inside the wiring harness. With the ignition off, measure the resistance among the cooling fan transfer receptacle at the harness (you will have to unplug it to achieve this) and the cooling fan relay coil socket. One of the coil socket receptacle contacts need to be related at once to the cooling fan transfer receptacle at the harness. Put off the cooling fan relay, then degree between contact 2 on object eight in the drawing and twine l or wire l/b on item 10. (Need to be 0-ten ohms). If now not, the wiring harness has an open between the ones factors. Because you've got already swapped relays and switches, this is probably the case. The most likely failure factor is the stop of the harness that connects to the cooling fan transfer (object 10) at or above the cooling fan transfer receptacle, on account that this receptacle is on the transfer (object 10) that's at the motor and vibrates with the motor, that can fatigue the twine or the crimp connection at the receptacle. You can try cutting the receptacle off of any other vehicle as far up the harness as viable (so that you have the cooling fan switch receptacle on the end of say, 1.5 ft of wire), doing the identical for your vehicle, and splicing in the "new one" (with each solder and electrical tape, for certain) on the factor where you cut off the antique one. Allow us to understand what takes place!!!!.
