There is a hollow screw with a spring that fastens the side mirror to the mount. There are grooves on the inside of this screw looking from the mount (I removed the side mirror and mount from the door). Is there a special tool to fasten this screw especially when there are 5 wires going through the hole? I removed the door panel already. Thanks guys,

Problem solved, went to the automotive store and bought a large flat screwdriver, this did the trick. It's always amazing what proper tools will do for you,

Yes there is a special too. I mention this even though you have managed to separate the mirror because getting it back together sux even with the tool cause you have to over come the spring. If you do not torque tight the hollow bolt you will be having mirror off the car again soon when the bolt backs off from vibration and folding the mirror.

 

Yep, that's exactly what happened, was folding the mirror regularly and eventually it became loose and then so loose I was afraid of losing it.
