If that unit detects an error it will not engage the A/C compressor to avoid it getting damaged. One other reason why the A/C compressor does not engage is the fact that the system may be low on R134 refrigerant. Typically older cars may have very slow leaks that may require top off with refrigerant every couple of years.
