Radiator fan wiring. . . what would happen if . . .

So if you have a 2 speed fan but only the appropriate wiring to make it run on one speed (like me)

What would happen if you made a take off for the life and connected it to the unused connection on the fan motor??

I.E
Earth - Earth
Live 1 - high speed
Live 2 - low speed

Any ideas? I would test myself but its raining and I dont want to uncover the car

See photo below but with an additional live wire running to the middle contact

Well if the take if is connected to the Radiator switch (using a 3 speed switch on the radiator) then you would get low speed at first, then if your temp exceeds the low setting you get the high.

If you have a 2 speed switch on the radiator, then using the high setting makes more sense, as you don't want the thing to run low speed, if you are needing to "Cool it down now mode"

I mean I think the single speed fan was running at the "higher" speeds usually.

I wouldn't connect both to the same pin on the radiator switch as it won't run any faster really.

But then again I have never had a non-A/C equipped Golf/Rabbit/Cabriolet ever.

As far as the flakiness of the connection on the motor, that isn't uncommon about the pins…. I have one of my Cabriolets sockets on the Fan connection -Tie-Wrapped to the Fan shroud to ensure that the connections stay tight.

You did see my thread on how to make the Fan Shroud easier to get on and off with a few snips of a tin snip?

Ah I get you, so if I was to fit the appropriate thermoswitch at the rad I would get 2 speed but as it is dont bother.

I've already taken my fan off, the shroud came off in about 2mins.

Took longer to get the cover off the car

that would be perfectly fine, with uk climate the 2nd speed is never used anyway
