Ok on my truck 1985 c10 i just got, the power door lock button rolls down both windows with the key on or off. with the key on the power window button unlocks the door.

Has anyone else ran across an issue like this ?

Sounds like a PO didn't know how to wire up PWs or PDLs. I would guess to say the PO added PW/PDLs to the truck.

BTW, Welcome to the site.

Strange, almost as though the lock power is going to the windows.
Do the doors lock when you hit the window button?

Also, these trucks do not have relays unless they were added by the PO.
Relays are added to boost the power to the motors to increase the speed.

If that was the case they could have been wired incorrectly.

Yes the locks work with the window button only when the key is on the windows will roll down with the key off like the door locks should Im just assuming the PO wired the switches to the wrong motors

After looking at the wiring diagrams I noticed the unlock motor and the power window motors have the same plug so i swapped them on both doors and it works like it should now
