Recently (several weeks) found an Executive door mirror in a local breaker after searching for many months, huzzah!
Was so chuffed to have the ext. thermometer back and a working passenger-side door mirror.
All was working fine until I changed the battery yesterday

On the way home the drivers window went haywire, must have lost the end points for the one-touch up and down.
Several attempts at lowering and raising the window seemed to have fixed that.
Then later in the day I parked up and folded the mirrors, because I could

The adjusting joystick still moves both mirror glasses but not much use as I can only see me in the mirrors

I disconnected the battery cables and held them together for thirty seconds to reset and discharge all capacitors as recommended by a mechanic friend of mine - no change unfortunately

Any ideas on diagnosing or even a fix please?
