Yup.. Nakatago ung putol na wire sa may firewall eh saka thats the last thing on my mind. Additional learning for me.

BUT my point is, dont blame the tech. Some times, they just cant attend the needed seminar/lessons for new car aircon system and wala silang expensive diagnostic tools para makita ang AC sensor performance. Karamihan ng ac tech sa banawe is basic acu lang kaya at di na updated sa changes in new car acu software.

I salute them for being honest at least at I refer ka nila sa casa. In some techs, mag trial error yan at kung anu anu ang ipapapalit sa yo like compressor, etc, kahit they dont have a clue na yun talaga problem.
