For 1990-2009 cars only
Functional Test
| • | The operation of the air conditioning (A/C) blower at all speeds in any position except the OFF position and the engagement of the A/C compressor clutch will indicate that the electrical circuits are functioning properly. |
| • | The same "hand-felt" temperature of the A/C evaporator inlet pipe and the A/C receiver/dryer or the dehydrator surface of an operating system will indicate a properly charged system. |
| • | The operation of the A/C control head will indicate proper functioning in order to distribute the air from the designed outlets. |
