Whenever i engage my 4x4, the 4x4 light flashes. It didn't used to do this. Its annoying watching it flash. Any ideas what could be causing it to flash?
Your 4x4 system uses air/vacuum power to engage the 4x4 system. The flashing 4x4 light indicates a leak has been detected in the system. Depending on the severity of the leak, the 4x4 system might not be fully functional and wheels may intermittently slip, or not lock at all.
There is a pump located behind the front bumper that maintains pressure in the system. The flashing light could be caused by anything from a bad pump to a small leak in an air/vacuum hose.
