I have a 1999 toyota corolla and once i flip the ignition turn on the motor fan activates with out the engine being on. The engine is bloodless and the whole lot. I have researched and discovered out which relay switches are for each fan and changed them, i've replaced the engine coolant sensor next to the thermostat, and i've replaced the laptop. Granted all substitute parts had been used. Relays had been taken from a junk yard however had 6 general relays of the equal numbers, and 2 sensors. I am gambling off of the chances that there is no way that every one relays and sensors are awful, and the pc i ordered was used as properly. I do not believe its the laptop but wanted to attempt. The auto does no longer overheat or have some other malfunctions. My simplest challenge is that the fan may additionally finally burn out from constantly strolling, and that its something that i need to know what is incorrect with it. Do you've got  any idea what it can be?.

My 2003 toyota corolla with one hundred seventy five,000 miles turned into displaying the take a look at engine light. My buddy ran a test and the code p0770 got here up, that is shift solenoid 'e' malfunction. While i'm at the parkway, i do.

This is extra than probable what they did it is where it's immediately to the fuse box beneath the hood to a hot plug to a warm twine so as quickly as you switch your ignition and it'll begin as soon as you switch it off it will flip off i've executed this too many. If the cooling fan switch seems to be caught in the off position, but then you definately degree a brief circuit (0-10 ohms) between the cooling fan switch terminal and the engine block (indicating the cooling fan switch is closed), then there could be a fault (open) within the wiring harness. With the ignition off, degree the resistance among the cooling fan switch receptacle on the harness (you will ought to unplug it to achieve this) and the cooling fan relay coil socket. One of the coil socket receptacle contacts should be linked immediately to the cooling fan switch receptacle at the harness. Do away with the cooling fan relay, then degree among touch 2 on item eight in the drawing and cord l or cord l/b on object 10. (Need to be zero-ten ohms). If now not, the wiring harness has an open among those factors. Seeing that you've got already swapped relays and switches, that is probably the case. The maximum possibly failure factor is the give up of the harness that connects to the cooling fan transfer (item 10) at or above the cooling fan transfer receptacle, in view that this receptacle is on the transfer (object 10) which is on the motor and vibrates with the motor, that may fatigue the wire or the crimp connection at the receptacle. You may strive cutting the receptacle off of some other automobile as a ways up the harness as feasible (so that you have the cooling fan transfer receptacle at the give up of say, 1.5 feet of wire), doing the equal to your car, and splicing inside the "new one" (with each solder and electrical tape, for certain) on the point where you narrow off the vintage one. Allow us to recognize what takes place!!!!.
