2002 BMW M3: HAL in the HVAC
June 30, 2008
Here's an observation I had in our long-term 2002 BMW M3 over the weekend.
The fan delivers air to the cabin with a peculiar whooOOSH.... whooOOOSH... whooshwhooshwhoosh... . whooOOSH sound that is especially prominent in the first 5 mins after the car is started.
Anecdotally, the climate control system in my old E36 M3 did this exact same thing before it had a massive freak-out and stopped working entirely.
Sign of impending demise, or "it's normal, they all do that"? Stay tuned.
