Pwr Door locks lock by themselves even when door already locked

[tinner105]

My friend has a 01 f150 screw. His power door locks were locking when the truck was put in drive like normal. But now it does that and then randomly locks all the doors again even when they are already locked. Does that throughout the day randomly.
I found the page on disabling the auto locking feature
Thank You
I disabled the auto door locking feature and it doesn't seem to be doing it anymore, but i would like to figure out whats wrong and fix it.

Wanted to add this info as well.. he has a problem with the window controls on every door except the drivers. you can only open the windows from the master/drivers switch. The window unlocking switch on the master controls is not working. he replaced it with a new and fried it almost immediately. At $100 buck too.. OUCH

I searched and went through 19 pages of door lock probs and didn't find a similar problem.
But I did find out why his gauges would all max out and then drop to "0" when he started it up. A bad battery.... i did notice it was cranking a little slowly, but i would have never guessed it would have been the cause of the gage problem.
He had a IAC problem as well, but i knew that one.

thanks for the great resource for Ford truck repairing and maintenance.

Also i cant remember if it was here or not but somebody had a link to get into the OHIO library system and access to repair and tech info for our trucks.
Does that ring a bell with anybody?

Thanks
Tony

My friend told me today that the autolock feature is back. So I don't know why it would activate again.
