Volvo 850 AC Damper Motor Control Testing

To resolve my damaged Volvo 850 vehicle's AC panel issue, I am opting for a replacement with an Arduino and 3D printed panel. Firstly, search for the Volvo 850 Auto AC Heater Systems manual to understand pin definition. Purchase essential parts such as L298N (x2), Arduino, and others. Utilizing Arduino, read damper motor position [0-5V] and control it using L298N (12V). Future enhancements include controlling AC compressor relay, five damper motors, and fan speed. Additionally, plan to integrate temperature sensors and voice recognition chips for commands like "warm," "cool," "more fan," and "lower fan." Eventually, I aim to eliminate the need for the original AC panel altogether.
