The splice locks should be pushed in all the way with a crimp tool or at the very least with a pair of good pliers, they wont work unless you do this.
Its even better to solder the connections.
Some cars seem to have the mirror switch wired the other way to mine (Unless its mine which is wrong)
Just change around the two wires to the mirror switch and this will fix the backwards fold/unfold operation.
You should be checking it works before putting the door card back on and then immediately afterwards to ensure you haven't dislodged anything whilst putting it back.
All I can suggest is check everything and also the fuse in the live wire to the unit.
If you cant get it to work pm me with your number and ill call you to see if I can help,
