Intermittent Silverado Four Wheel Drive Selector Buttons
Here's what looks to be a common problem on these trucks.
MODEL
SYMPTOMS
- Intermittent operation of 4WD
- Gets stuck in 4WD, then switches out after some random delay
The Silverado 4x4 Dash with Pushbutton Module
PROCEDURE
- Carefully pull off the bezel ring. It just unclips. Don't break it.
- Remove the 4WD push button assembly and unplug from wiring harness.
- Look closely at the solder joints on the back of the connector where the wire harness plugs into the push button module.
If the solder joints are cracked (you may need magnification to see the cracks), then resolder. This is the source of your intermittent problem.
- After repairing solder connections, reassemble in reverse order.
- OFF ROAD TESTING TIME.
