E70 LCI folding mirror help pls

[HarryWare]

Morning all, new here and looking for some advice. I've always found answers over the last 20 years on forums using the search function etc. But I'm stumped this time. I have recently acquired an E70 LCI with memory seats and camera in wing mirrors. The mirrors tilt, but the passenger mirror won't fold when pressing the button inside the vehicle. The drivers side does. My question is, where the heck is the motor for it? I can't hear any motor sound when the button is pressed. I've taken it somewhat apart. Is it in the arm of the mirror? And can it even be replaced? Any advice would be greats, Cheers all

Pretty sure it's in the arm.

Cheers for the reply buddy. I had checked Realoem pictures but didn't really confirm it. But logic is telling me it has to be in the arm due to where it folds....just hoping I can try and replace the motor only...fingers crossed. Cheers again
