Begin A/C Switch replacement by removing the accessory trim plate and the screws attaching the A/C Switch. The A/C Switch must be extracted from the instrument panel to access vacuum and electrical and temperature cable connections. The vacuum harness connector requires removal alongside several electrical connectors which include a/c mode switch and a/c control illumination and a/c blower switch and rear defogger. Four components include a/c mode switch, a/c control illumination, a/c blower switch, and rear defogger. To take off the temperature control cable from the A/C Switch, users should employ a small screwdriver to unclip the control cable connectors. Begin installation by attaching the temperature control cable connector to the A/C Switch and then proceeding with connecting the electrical connectors: rear defogger, a/c blower switch, a/c control illumination, and a/c mode switch. The system consists of rear defogger and a/c blower switch and a/c control illumination as well as a/c mode switch. The A/C Switch requires installation along with connection of the vacuum harness connector. Tighten all screws to 2.2 n.m (19 lb in) according to fastener notice specifications. You need to reinstall the accessory trim plate as the last step.
