1992 Toyota Corolla Radiator Fan

Could be the engine temperature gauge switch or the fan relay

Check that fan switch (located under distributor in coolant distribution block) is connected.

It is white and round, if connected, then as RAZ said, stuck relay or bad fan switch.

I located the fan switch and it is connected and I also located the relay, when I disconnect the relay the large main fan turns off (the one behind the rad) but the small one stays on same thing if I remove the main 30amp fuse for the fan large off small on. My question is How do I narrow down which it is the relay or the fan switch.

Help! and thank you!

I would replace the fan switch. It is designed to run all the time if disconnected or switch is faulty.

Thx Raz, I replaced the engine temperature gauge switch and the fan switch and both looked cruddy and needed to be replaced (corroded) but problem persist. I am about to pick up a relay and replaced that and we'll see what happens. Anyway, thanks for the advise.

If you have a local U PULL IT, go and find a 90-92 Corolla or Geo Prizm.

Remove the two fuse boxes to use as spares, (they just unplug).

They contain relays and fuseable links which are hard to find and VERY expensive it you have to get them from Toyota.
