Well, I have a Glanza S/Ep91 and I got it with the fan wired to turn on as soon as the ignition key is 'ON'. This was done by jumping a wire directly into the fan feed wire. Now, I have removed that wire and would like the fan to be temperature controlled but that is where I have run into problems. (1) My thermostat housing has no hole for a thermostat fan switch. (Somehow the orientation of the image is flipped 180 degrees. It is upside down and pointing to the left instead of right). There are no threads in the opening and the hole is basically sealed with metal.
(2) There is no wire on the engine looms that seems to have been for a thermostat switch if the housing was changed. I have verified this by following the wires on the the Fan No.1 relay in the engine bay fusebox and the wires from both sides of the relay switch lead into the cabin. One is on the loom that enters the passenger side while the other is on the loom that enters from the middle.
The empty relay slot is where Fan No. 1 relay sits.
The white/blue wire at the top right enters the cabin from the middle slot in the engine bay. The other wire is light blue/red (not visible here) and is on the bottom loom in this image which enters the cabin on the passenger side.
Now my question is, do you suppose that the radiator fan is controlled by an ECU? Or am I missing something here? Maybe the thermostat housing was switched with one that does not have a provision for a thermostat switch? Or am I following the wrong relay? Though I can confirm that when the bottom relay pin is grounded (in the second image), the fan turns on. That is how I am running it for now by grounding that pin so that it still runs all the time when the ignition is 'ON'. I would like to try and run it up to temp without grounding it and see if the fan kicks in.
Anyone with a better idea or explanation, suggestion? Thanks in advance!
