Thanks Howard for posting this diagram.

I've always had a "whistling" sound coming from under dash on my 49 when going down the road, and it started after a restoration on the engine compartment.

Checked your diagram to my hoses and sure enough, the hoses into heater control were reversed!

Thanks again.
