Driver power mirror mind of its own

[Payton34]

Last week My driver mirror started tilting down on its own right after I would start the truck. I turned off the auto reverse mirror tilt function but it will either turn in or down after I back up then put in drive. I tried disconnecting battery to reset computer. But it still does it’s own thing.  Then today after got home and turned truck off the mirror started title up. 
 

any ideas is there a module to replace for mirrors?
