I just recently bought a '92 525i - everything on it is sweet. Can't believe all the little features - but BMW left out a simple cup holder; seems like a no brainer to add.
However, aside from that; my heater is not pushing out enough heated air. The fan sounds like its working and gets louder as you turn up the fan knob, but the expected air output is minimal if not very low. There is heat but not much of it is coming out. What should I be checking for, or adjusting or cleaning on this baby?
I do have the Bentley service manual, but it dosn't give me troubleshooting tips on heating. My AC seems to work fine.
Colder and colder in Seattle,
