Electric Radiator Fan - always running when engine is on

[tmurph05]

Hi,

I'm new to volvos and servicing them. I recently noticed my electric blower fan (right in front of the motor) is constantly running while I am driving. The a/c is off (at least the light is and the compressor doesn't seem to be engaging) and it is also winter here. What could be causing my electric fan to run all the time and how can I fix it? Thanks!

There should be a control wire that I'm thinking is pink connected to the fan. If you disconnect it and the fan still runs then the controller is bad and you need a new one.

I disconnected that wire, and the fan turned off. What does that mean?

Well, I disconnected the entire wire hub (red black and pink) are you suggesting I only remove the pink wire?

[ericjp]

Just the pink one, its the signal wire that tells the fan to turn on.

How do I remove it without damaging it?

You need to depress one side of the connector and pull it out.

Is this the pink wire you are talking about? It's hard to pull out.. I don't want to wreck it.. IMG_5530.jpeg

There should be another connector in that wire further to the passenger side. It should be clipped onto the fan shroud.

That wire terminates on the fan, and plugs in there. If I trace it backwards, it heads to the drivers side. Is there another wire?
