Does it happen when you adjust any of the 4 mirrors segments?

Yes it does.

Yes it does.

Assuming that the fise survives when mirror adjustment is not attempted, that would suggest that there is a problem with the common control lever,
Possibly the fuse will blow when horizontal or vertical movement is attempted but not both.

Thanks, I will try replacing the controller and see. It could be as you said that it blows when I do certain movements.

I suggest checking that the fuse only blows when particular movements are attempted.

Another possibility is that the connection that is common to 8 motors has an earth fault. This would cause the fuse to blow when one direction only, of movement for all 8 motors. Earth faults can occur when the door loom rubs against the body, and movement occurs when the door is opened or closed.

To save fuses when checking, I would be tempted to connect a 21W bulb in place of the fuse. However that is easier said than done.

@Communicator just checked, I can move in all directions except the bottom mirror on my left hand side. Then the fuse blow immediately.

any help?

Problem solved; one of the connecting pins under the window switch panel was bent and touched the one next to it causing a weak turn signal in the mirror as well as a fuse kept blowing when adjusting.
