I'm not sure if this is a common problem or something unusual with this car. The car is a 92 525I.
The AC/Heater blower fan works fine on all speeds since i can hear it. But get very little air through any of the vents, no way for it to keep me cool in 80F+ weather.
Is this an easy fix? I read somewhere that the AC/Heater filter needs to be changed annualy for the air to pass through the vents correctly, that true?
If so, where is this filter and is it easy to get to?
The person i bought this from seemed highly unlikely to have changed this, but please let me know if there could be any other causes for this.
