I have the memory mirror problem where the memory mirrors wander from
the programed presets when the vehicle is unlocked using the keyfobs.
Some things I have noticed:

The problem seems less frequent in warmer climates.
Most of the mirror wander aims it downward, but it does move sideways
too.
It affects both mirrors and varies day-to-day.

I've searched and read several postings about the problem but haven't
seen a solution. Does anyone have any experience with either fixing
the problem or disabling the memory feature?

Thanks in advance for any help! My ZJ is at 130K and running great!
In fact, it's gone 9000 miles in December and January so far. :)
