To reset the blend door actuator, turn off your engine and disconnect the negative battery cable for approximately 10 minutes before reconnecting it.

This should reset how your blend door actuator operates and hopefully resolve any issues with your car’s temperature setting.

2. Remove The Door Panel:

If you’re having trouble controlling the temperature in your car, it may be time to remove the door panel and reset the blend door actuator.

This can be tricky at first if you’re unfamiliar with how to do it, but luckily it’s pretty straightforward.

You’ll need to start by removing the inside door handle and removing all of the screws or plastic retainers from around the edges of the door panel.

After completing the initial steps, gently remove any clips from the back of the panel and disconnect all wiring.

Then, slide out the door panel to access and reset your actuator for further inspection.

3. Disconnect The Wires:

Disconnecting the wires that are connecting your vehicle components can seem intimidating.

For example, resetting a blend door actuator requires removing the negative cable and the performance chip to gain access to the build door actuator.

To begin, identify the negative cable by looking for signs of corrosion on the connectors near both ends of the cable.

Once you’ve found it, loosen any screws securing it before lifting off the terminal clamp from its anchor point and prying apart the negative cable from its connector.

Next, withdraw the performance chip from its cradle and disconnect it from any remaining cables or termination clips so that you can safely access the blend door actuator.

Knowing how to disconnect wires can save hours of labor if repairs need to be done around your car or truck!
