LFA Blower Motor Issue

Experiencing a strange issue with my 2011 Lexus LFA, gasoline engine, with 117663 km. The blower motor isn't working. I suspect it's an AUC sensor fault, possibly a defective cable or plug connection? Anyone else run into this?

Summary of the thread

A 2011 Lexus LFA owner is experiencing an issue with the blower motor not working and suspects a fault with the AUC sensor, possibly due to a defective cable or plug connection. Another person suggests checking the wiring harness for the air quality sensor, which is typically located behind the glove box. After inspecting the harness, the owner decides to take the car to a workshop, where a defective cable is diagnosed and repaired.

Hey, I had something similar happen on my Lexus IS. The auto recirculation wasn't working, and it turned out to be a faulty cabin air sensor. Have you checked the wiring harness for the air quality sensor? I would start there.

Thanks for the tip! Where exactly is the air quality sensor located? And how involved is checking the wiring harness?

On my IS it was behind the glove box, but its a Lexus, so it might be the same. Really easy to get to. Checking the harness involves just visually inspecting it for any obvious damage, loose connections, or corrosion. But honestly, if you're not comfortable with that, I'd just take it to a workshop. Could save you a headache in the long run.

Appreciate the advice. I'll give the harness a look, but probably best to play it safe and take it to a workshop. They diagnosed it as a defective cable. Fixed for 95€. Thanks again!
