Does the system have power? If the A/C controls in your 2005 Toyota Sequoia are not working, there are a few potential causes for this issue. Here are some troubleshooting steps you can follow:
Check the A/C fuses: Start by checking the fuses related to the A/C system. The fuse box is usually located under the dashboard or in the engine compartment. Refer to your vehicle's owner's manual for the exact location of the fuse box and the A/C-related fuses. Inspect the fuses and replace any that are blown.
Test the A/C control panel: The A/C control panel itself could be faulty. Check if any of the buttons or knobs are unresponsive or stuck. Try pressing each button and turning each knob to see if there is any response. If the control panel is unresponsive, it may need to be replaced.
Check the A/C blower motor: The blower motor is responsible for blowing air into the cabin. If the blower motor is not working, it can give the impression that the A/C controls are not functioning. Turn on the A/C system and listen for the sound of the blower motor. If you don't hear anything, it could indicate a problem with the motor or its electrical connections. The blower motor may need to be replaced.
Inspect the A/C compressor: The A/C compressor is responsible for compressing and circulating the refrigerant. If the compressor is not functioning, it can affect the performance of the A/C system. Check if the A/C compressor engages when you turn on the A/C. If it does not, it could indicate a problem with the compressor itself or its electrical connections. A professional mechanic can further diagnose and repair any issues with the A/C compressor.
