My drivers side window auto drops as normal when I pull the handle to open the door but immediately upon releasing the handle it pops back up to full closed position with the door open.

It makes no difference if you open the door from the inside or the outside. Drivers side only. No battery issues. No work has ever been done in this area. All other window functions are perfectly normal. All lock and unlock procedures working normally. 

I'm leaning towards replacing auto drop micro switch assy. but I thought I'd present the issue to the forum first.

Thanks much, Paul

Sometimes it helps to go through the window "relearning" process.  If that doesn't change anything, then probably is the microswitch.  Roll window all the way down and hold the button for 10-15 seconds.  Roll window all the way up and continue to hold button for 10-15 seconds.
