Welcome to 2CarPros. If it blinks while switching from 2WD into 4WD then stays solid once into 4WD it is normal. If however you switch it into 4WD and it still blinks constantly there is a problem. The blinking light also means there is a code stored that can show you what the issue may be. The first step would be to scan it and get the code. Then test the parts as needed.
