Hello Guys,

My best friend having some problem with the AC. I told him to come to me for ISTA scan. I did it and I got 2 error according to the AC Compressor :

There was test plan but I could not find any solution or I did not get what exactly saying.

I would like to share the symptom maybe you guys can help me out.

TITLE : Functional check, noise, smell
ABL : Heating and Air conditioning functions : Refrigerant circuit check, noise, smell
Detail : 80436E compressor clutch : Break in wiring or short circuit to B+

System Check : B7F8B8 Connection between headunit and Bluetooth aerial foot : open circuit

Car is 76k miles on odometer.

I will appreciate any help. Thank you!

Similar problem on 2012 F30 335i with 75k
A/C doesn't work.
Looking for solutions, mechanic suggested replacing a/c compressor or HVAC head unit/controller.

Ive got a 2013 F30 328xi same code 80436E.
I installed a new head unit and i am thinking that is either causing the issue or i pinched/damaged a wire at some point.

voltage at compressor electrical connection is reading 10-12V but clutch wont engage.

I have a 2015 320i and I was driving the other day and noticed the AC wasn't blowing cold. I checked 134a levels was good and I checked all fuses, does anyone know how I can test the clutch or anything else I can do to fix this issue. please help. thank you

If your ac doesnt blow cold air, compressor doesnt kick in probably or you are low in freon. How did you read the freon level? With pro tool?
