Guys, I need some help with the colling system wiring of my 1993 Mirage. Basically yesterday while I was driving back the temperature shot up and boiled. I discovered the issue was that the radiator fan was not working. While I was investigating the problem I realised that the wiring of the fan was a bit of a mess. And because the fan was changed (possibly a couple of times but I changed it 6 months ago due to broken fins) and the wiring was modified (possibly by the AC guy a couple of years ago) I was at a loss to figure out how the damn thing should work. From what I can figure the thermosistor switch in this car is in the radiator in the bottom. It has two wires but only one is connected to anything, the other was blanked out using insulation tape. Something is not right there. I haven't figured out whether the termosistor switch works anymore or not. The fan connector (no gurantee this is original but could be) seems to have three wires coming out of it. The fan sees to need only two but of course this is not the original fan. The thermosistor switch has a 2 wire connector. When I found the circuit the thermosistor switch had one wire joined up with the ground of the fan directly though there was nothing connected to the other end of the thermosistor switch. The positive wire was connected to one of the wires in the fan connector and one wire of the fan connector is not linked to anything. A neighbour helped me a bit and he figured that there were two ground wires and one positive in the fan connector (at least now, remember wiring could have been altered at the other end) and if the fan is connected to one (coloured) ground wire and the other positive wire (this wasn't how I found the circuit but this is what we figured) connecting the battery negative to big ground wire on the fan connector seems to start the fan. Now this could be the wire the thermosistor switch is supposed to connect to but as I said before it had only one wire connected to anything. But the radiator fan should also come on when the AC is on with the condenser fan. That does not happen. I have found one positive wire that was lying around again not connected to anything that comes on when the AC circuit is on, so this could be the missing link, but I am not sure where its supposed to connect to. From what I understand the radiator fan should work in the following way. If the water temperature is above 85C the themosistor switch will complete the circuit and turn the fan on. When the AC is turned on another relay also triggers the radiator fan on. I have found this circuit diagram for an older Mitsubishi but assume it could be similar in my car as well. There are 3 relayes in my setup as well (on the far side near the front headlamp). http://manual.pajero4x4.ru/?wpfb_dl=3571 Could somebody confirm that the setup is the same in later Mitsubishis (1993) and could someone please explain connections going into the radiator fan motor, just to confirm what I've assumed. Thank you!
