Sorry I haven't been here in a while but since I have no real expertise and haven't been having any problems... Anyway, Now I have a problem. By the way, I keep trying to make a donation but it keeps failing.

So, my issue is that my power door locks will not lock. Not with the fob, not with the button, not when it's put into gear, nothing. However, it unlocks as advertised, i.e., with fob, when put into park, and with the passenger unlock button, not the driver's. So, I replaced both driver's and passenger's switches (located on each respective door arm rest). Has anyone had any experience with this issue? Thanks for any help you can give.

Here is a start for you. Lets get looking at the wiring and see if the signal are sent correctly.

 

Great, thanks. My cheap manual didn't have a schematic for this system. I'll have to break out the multimeter and shoot some wires.
