2004 GMC Sierra V8 Four Wheel Drive Automatic 76000 miles
The other day I cut my truck off, keys out and I heard something running. I found out that its the motor for the anti-lock braking system underneath the driver's door. It will not stop running - looking for some advice. If I leave it like it is it will run down the battery. Someone told me that all of the brake lights are tied into this device - is this true? What would make it continue to run and how do I troubleshoot?
