II. Troubleshooting Steps
Before seeking professional assistance or considering a complete replacement of the AC control unit, you can try troubleshooting the issue yourself. Here are some steps you can take to diagnose and resolve the problems with your ’99 Honda Accord’s AC controls.
A. Checking the Basics
Start by checking the basics to ensure the AC system is receiving power and that there are no simple issues causing the malfunction.
1. Verifying Power Supply
Check if the AC system is receiving power by:
- Checking the AC system’s fuse
- Verifying that the AC compressor is engaged
- Ensuring the AC system is properly connected to the car’s electrical system
If you notice any issues with the power supply, address them first before proceeding with further troubleshooting.
2. Checking the Fuse Box
Inspect the fuse box to see if any fuses related to the AC system are blown. If you find any blown fuses, replace them with the appropriate ones according to your vehicle’s manual.
B. Inspecting the Control Panel
If the AC system is receiving power and the fuses are intact, the next step is to inspect the control panel itself. There may be an issue with the control knobs, loose connections, or visible damage.
1. Removing the Control Panel
Start by carefully removing the control panel from the dashboard. Refer to your vehicle’s manual for specific instructions on how to safely remove the control panel.
2. Examining the Control Knobs
Inspect the control knobs for any signs of damage, such as cracks or wear. If you notice any issues, consider replacing the control knobs to see if it resolves the problem.
3. Checking for Loose Connections
While the control panel is removed, check for any loose connections between the AC controls and the wiring harness. Ensure that all connections are secure and properly fastened.
C. Testing the AC Control Unit
If the control panel appears to be in good condition and the connections are secure, the issue may lie with the AC control unit itself. Testing the AC control unit can help identify any underlying problems.
1. Accessing the AC Control Unit
To access the AC control unit, you may need to remove additional components or panels. Follow the instructions provided in your vehicle’s manual to safely access the AC control unit.
2. Inspecting for Visible Damage
Inspect the AC control unit for any visible damage, such as burnt components or loose wires. If you notice any damage, it may indicate a need for replacement.

Using a multimeter, test the electrical continuity of the AC control unit. Follow the instructions provided in your vehicle’s manual to perform the testing accurately. Compare the results to the specifications outlined in the manual to determine if the AC control unit is functioning properly.
If the AC control unit fails any of these tests or exhibits signs of damage, it may be necessary to replace it.
III. Replacing the AC Control Unit
If troubleshooting and testing reveal that the AC control unit is faulty, replacing it is often the most effective solution. Here are the steps involved in replacing the AC control unit in your ’99 Honda Accord.
A. Gathering Necessary Tools and Materials
Before starting the replacement process, gather the necessary tools and materials. This may include a screwdriver, a trim removal tool, and a replacement AC control unit.

As a precautionary measure, disconnect the negative terminal of the battery to disable the electrical system during the replacement process. This will help prevent any short circuits or electrical shock.
C. Removing the Old Control Unit
Follow the instructions provided in your vehicle’s manual to remove the old AC control unit. This typically involves removing any panels or components obstructing access to the control unit and disconnecting the wiring harness.
D. Installing the New Control Unit
Once the old control unit is removed, carefully install the new AC control unit in its place. Ensure that all connections are secure and properly fastened.
E. Reconnecting the Battery
After the new control unit is installed, reconnect the negative terminal of the battery to restore electrical power to the system.
IV. Calibrating the AC Controls
After replacing the AC control unit, it may be necessary to calibrate the AC controls to ensure proper functionality. Calibration helps the controls accurately interpret user input and adjust the AC system accordingly. Here’s how you can calibrate the AC controls in your ’99 Honda Accord.

Once in the calibration mode, follow the on-screen instructions or prompts to complete the calibration process. This may involve adjusting the temperature settings, fan speed, and control knob positions.
Upon completion, the AC controls should be properly calibrated and ready for use.
