Driver side door lock button not working

My door lock button on the driver side stopped working. The unlock button on the same rocker switch still works normally. I can still lock all doors with the key fob, and the passenger side door lock button. So it seems to be isolated to the button. The button still feels normal, springs back when pressed, so no obvious damage. I pulled the bank of buttons out and took apart the plastic casing, and don't see any obvious damage there either.

Anyone experience this before? Anywhere else I should check before swapping out parts?

 

Damn electronic crap! Did you try throwing it up against a wall or something.

 

while out did you ohm the switch?

 

I didn't measure resistance but I did check continuity with the tone mode on a multimeter at the pins on the PCB. Beeps when I push the slider one way and stops when I push the other way, so seems to work. But I didn't check at the pins of the harness since I didn't know the pinouts.

 

I’m going with “It is the switch”

The switch grounds the Blue/White wire to the W/B wire.
The Blue/White goes the the Body ECU.
(See below for diagrams)

If you were to get creative, you could possibly ground the wire at different locations and see if it’s the Switch, Wiring or Body ECU. (IF YOU DO THIS AND BAD THINGS HAPPEN DON’T BLAME ME)

Or play it safe and unplug all the connections and test it with a DVOM. (DO THIS)

Here is a link that may help.

Instead of using a jumper wire to ground use a test light that way if you touch the wrong wire all that will happen is your test light will light but it will still be enough to to trigger the lock signal. If you touch the lock signal wire at the switch and your doors lock then you have a bad switch.
