Q and A..."Ambulance fan" and lights...

We bought a P21 new in 1974 that came standard with the fresh air fans. The noise was acceptable then and while the mists of time may have clouded my memory somewhat, the ones in my 79 do not seem to be any noisier.

I have driven air cooled vw's continuously since the late 60's. They all are noisy in one way or another compared to most any other vehicle.

Oh and we still have the first new one we ever bought and the fresh air fan in it is not exactly quiet either. The trade off is acceptable for me. So be it.

Where can you find the riveted brass nylon spacers with the ground tabs. I need to repair my heater controls but can't find any parts places that carry these.

Thanks!

If I am not mistaken the round cylinder on the early ones is metal. On the later ones it was plastic. I would imagine the difference in noise between the two would be signifagant. Adding a couple small pieces of sound deadener in that tube should greatly diffuse the nasty vibration resonance that most are experiencing. I don't know if they have sealed bearings but cleaning them and lubing them would also greatly help matters. Most are probably full of crud coming through the ducts.

So, has anyone looked into a modern replacement fan, that might be more efficient (with 40+ years of possible design improvements? )

I suppose that we'd need the OD of the unit, it's depth, and the current draw.
