My question is that the compressor keeps running and doesn't turn .

More than likely this is a leak. It could be in the lines, or the bellows (springs for air ride suspension types). If you don't hear air hissing under the car after the system is charged, test the output of the compressor.

Most the time it is probably a leak from air springs or lines. We usually use a smoke tester to find leaks in the system. Then check compressor output.
