Mirrors out of sync

[Demusman]

I just replaced my side view mirrors, both were suffering the clicking when folding but I took one out with a fence pole so figured I do them both.
Everything working fine except now they are out of sync!
ie when drivers is out, passengers is folded in and vice versa.
Tried extending the drivers side, then disconnecting power to it and extending the passenger side, once I return power, the driver side would fold.
Tried disconnecting battery for a half hour, no change.

Anyone know a way to resync them??
I have alfaOBD if it helps.

I'm spitballing here, but sounds like the motor polarity is reversed on one of them.
I don't know if you can determine which mirror is out of sync, but if you can figure which it is, you might try swapping polarity if it is a two wire hookup.
If it is three wire, two positive and one negative, you'd swap the two positive lead positions on the plug.

Yup, that did it.
Took the old one apart and found the wires.
2 wire, just swapped them and it's perfect.
