A/C Check
A/C CHECKFor A/CON output, blower must be basically operated. When blower speed 1 is selected, blower relay is turned ON and voltage is supplied to point "A".
When the supplied voltage at point "A" is entered into control connector C15 and at this moment when A/C ON switch is turned ON, voltage is supplied to connector C5 at 9 V or more.
