Can you Disable the auto door lock on 2008 Yukon the owners manual only allows to change from lock at transmission in gear or at speed I do not want it to lock unless I push the lock switch?

Answer 1

I wanted to do the same with my 2005 f-150, but couldn't find any real answers from anybody at a garage or dealership. I got lucky with my f-150, only because the signal wire from the ECM to the driver's door lock was a separate wire from the rest of the bunch. So I took apart my drivers door, jammed a test light in each and every wire terminal on the harness at the window controls, and drove around. Unlock the doors at a stop, then put the trans in gear and start rolling. They should lock around 5 or 10 mph. When they lock, your test light will light up when you are on the right terminal, showing you the signal wire. When I did that, I just cut the wire. Problem solved. But your vehicle might be different. Try it out and see. Your signal wire might be the same as another wire, so cutting it might effect some other window function all together. GOOD LUCK.
