AC not working, then worked after restart
Hi all, I live in sunny California and of course have to deal with heat and all that. Anyway I was on a 250 mile road trip today and it was 105F outside. I noticed the AC fan was getting less and less (but still sounded loud) and eventually over the span of about 15 minutes or so it dropped to zero. Like, I could hear in the dash that a fan was running, but no air was coming out of the vents. I tried cycling through the different vent modes like feet, windshield area, etc and it didn't work for any.
I stopped at a gas station, turned off the car and popped the hood to see if I could see if maybe a hose popped off or... idk. Didn't see anything out of place. Started the car again and the ac started working, blew cold, and worked great for the rest of the trip. Any ideas why that might happen??

Same thing happened the other day in my F30. Turned off the AC for 5 min then turned it back on and all was normal. So strange.

Glad to know I'm not the only one... Current plan is to just drop by the dealer and have them look at it, in case anything is in their system about the issue.

There's a BMW service bulletin about it: TSB 64 06 13 https://static.nhtsa.gov/odi/tsbs/20...47927-9999.pdf If the evaporator is freezing up, it will block airflow through the system. A quick fix is to just to turn off the AC, but leave the fan on. The evap will unfreeze after a little and once it does AC should start flowing again. According to my google research, If you go to the dealer for a more permanent fix they will either install a spacer for the temp sensor or reprogram the car to raise the evap temp by 1 or 2 degrees to stop it from freezing. |
