How to troubleshoot an A/C Switch on Toyota Corolla?

The first step of control assembly service and repair requires pulling heat control knobs out while using a screwdriver to remove the heater control name plate after releasing 4 screws. You should start by removing the A/C switch through the removal of its 4 screws located on the heater control name plate. The blower speed control switch requires users to start by removing the 2 bulbs then disconnecting the 2 bulb holders and thereafter removing its 2 screws. A screwdriver helps to open cable clamp claws which enable disconnecting the outer cables of the heater controls. Secure the screwdriver tip with tape before proceeding to remove inner cables from the A/C control assembly. The A/C control assembly receives the inner cables during reinstallation followed by the connection of outer cables. Reinstall the blower speed control switch with 2 screws while connecting 2 bulb holders followed by properly inserting the 2 bulbs. The installation process requires the A/C switch to be placed onto the heater control name plate along with the heater control name plate and completion with pushing in both heater control knobs.
