Aircon auxilliary cooling fan

Can't find any info on this. It squeals after starting the engine, sometimes continues throughout & sometimes stops. This is the fan that runs for a minute or two under the ac cover behind the fuse tray after the engine is stopped. very annoying.

Can anyone help on this one? I'm loathe to take it apart without some info. thanks

Re: Aircon auxilliary cooling fan

I think the fan you're taking about is called the ECU fan - a bit awkward to remove, but not impossible - they run on either nylon or brass bushes & dry out.
