August 24, 201214 yr comment_622895 hey my radiator fan runs full time if plugged in but was running properly up until my a/c compressor was pulled out any ideas?thanks Report
August 24, 201214 yr comment_622918 Did you pull the a/c out or was it a garage? Can you cheeck that the thermoswitch is wired in still and that it goes 'open circuit' when the motor is cold?? The switch might be faulty, or someone might have damaged it when removing the compressor & shorted it out... Report
August 24, 201214 yr comment_622932 This is normal, find the little blue plug for the air con and connect up the 2 pins, or just cut the plug off and solder the 2 wires together if you are never going to use the air con again. I had to do this, maybe just connect the two pins with a bit of wire first to see if it fixes your problem and if it does you can come up with a more permanent solution.

August 24, 201214 yr comment_622945 The temp sensor switch on thermo fans fail closed so the fan is always on. I would track down the temp switch and test it. Report

August 25, 201214 yr comment_623059 The temp sensor switch on thermo fans fail closed so the fan is always on. I would track down the temp switch and test it. I'm fairly sure corolla thermofan switches are normally closed, so for the switch to fail it would have to be stuck open. And I don't think it is the thermofan switch causing the problem. To the OP, when the aircon is removed, it leaves a little blue 2 pin plug unplugged and this plug is basically a second thermofan switch (it's wired in series on the same circuit as the thermofan switch), so by disconnecting this plug from the aircon, you are opening the switch circuit permanently and the thermofan will run until the switch circuit is closed when you turn the ignition off. Remove the blue 2 pin plug from the switch circuit by splicing the two wires that enter the plug together, the thermofan circuit will now be closed and the thermofan will no longer run constantly, but it will turn on when the thermofan switch opens when the engine gets hot. Edit: Just realised Trev already posted the solution, read that. Edited August 25, 201214 yr by rian Report
