Introduction

I noticed that the high setting on my climate controlled seats was not actually running on high unless I turned up the AC and selected that the air be dispursed in the vents facing my head. I personally did not like this and wanted to have my seat cooled at max blower speed, even if I did not have the AC running at full blast. This would enable conversation easier and minimize my back sweating and ultimately make it more comfortable for me during long car rides, like my current commute to the work office of over just over 2 hours.

Currently, I have taken the car seat connectors apart. I have found which power drives the seat blower. I have found the seat blower is driven with a PWM line from the seat controller ECU. I have figured out a way to control the seat blower by driving a mosfet set up to run the PWM signal's connection to ground with an Adafruit Board. - 4/15/2025

Next is to find out if I can read the OEM PWM signal with a GPIO or if I need to read in through a Low Pass Filter and read an averaged out voltage with an analog GPIO. Also need to figure out what kind of connector crimp terminals are on the connector. **Stay tunes to find out more**

Reading through wiring diagram to see how wiring is set up and see what connectors to tap into

Reading to see how OEM setup works

This is a read from the slowest seat blower setting.

This is a read from the highest seat blower setting, with the cars HVAC blowing at high and the vents facing the head.
