How to Replace Door Lock Switch in '07-'10 Silverados

Postby In2Trux [OP] » Oct 21 2010, 3:37pm

Remove and replace door locks in 2007-2010 Silverado.
List of Things You'll Need
  • Wide blade slotted screwdriver
  • 2 small slotted screwdrivers
  • 10mm 1/4 drive socket
  • Replacement switch from dealer

Goal: Evaluate for a faulty Door Lock Switch in a 2007.5 - 2010 Silverado; replace as needed

Requirements:
• Skill Level: Average
• Time: 1-2 Hours
• Special Tools: None

Isolate the problem and make sure it's definitely the switch and not a fuse, wiring, or an actuator:

• Driver's side doesn't work but the passenger side does.
• Driver's side doesn’t work under any condition.
. .o with door open or closed
. .o with key on or off.
• It must be a faulty switch – replace the switch.

Step-by-Step Description:
Step 1: Here is the door panel where the repair will be done

Pry the door grab-handle cover off with a wide blade slotted screwdriver.
With some upward force, begin to gently twist the screwdriver to pry the cover off.

Here is what the cover looks like. Take extra care to ensure you don’t break off the mounting tab.

Step 2: With the door handle cover off you can remove the top and bottom bolts with the 10mm socket

Step 3: With door handle gone. Now you can pry the door console up to gain access to the wiring harnesses.

With the cover off, the wiring is exposed

Step 4. I compared the switch from the dealership with the one in my truck. Top side

And bottom, just to be sure it is the correct part. Even the numbers matched!

Step 5: Unlatch the wiring harness plug, and lift the plug from the switch.

Step 6: Before installing the switch... Test it by plugging the harness into the new switch.

Step 7: Using your sharpest and thinnest flat blade screwdrivers, spread the sides to allow clearance for the switch to come out. Very important Note the tabs on the side of the switch that latch it into position – they must be released from the slots.

Do not pry it out, insert the screwdrivers then lift the switch out of its home.

Step 8: Then snap it into its home.

Step 9: YOU ARE DONE. Reassemble the door grab-handle and trim

Evaluation:
The door locks now work as they should.
Conclusion:
It was really a lot easier than I thought, and I am glad to share this ‘how-to’ with the group.

Could the problem be something besides the switch, if the switch on each door works for the lock on the door on which it is mounted, but will not lock nor unlock the opposite door. Also, the electronic key will not unlock or lock either door.

It's been a long time since this repair. And it's still working perfectly. And in that time I don't remember the part number.
Which is just as well... Your gonna go to GM to pick the part up. You might as well give them your truck info so you get the part specific to your truck.
Let us know how it turns out for you
