Driver's Front Electric Window Problem

[MK Radical]

Hi,

I have an O5 plate Subaru Impreza WRX and I have been having issues with the driver’s side front electric window.  There is a clicking noise every so often coming from inside the door.  When it clicks and you try to open the window there is a 5-10 second delay before the window actually opens.  I have had the motor and regulator replaced, which cost a fortune, but I am still getting the clicking sound and delay.  Could it be a relay problem, because of the clicking?  I feel it is a deeper issue to do with the electrics.  Can anyone help please?

Thanks.

Michael
