Few people know less about this than I do, so here goes... I have a '40 Chevy 2 door sedan that came with a Vintage Air Heater/Air Conditioner when I purchased it about 8 years ago. I recently had the car painted so it had to be disassembled. Not sure if the a/c unit was removed or not. I do know the heater worked great before I had the car painted but when I took it home from the painter I noticed the heater would blow hot air just fine for about 10 seconds then the air coming from the ducts would slow to almost nothing. If I turned the fan off then turned it back on again it would do the same thing...blow hot air for 5-10 seconds then gradually slow to just a trickle. Is this a vacuum issue? Or is there maybe a door that's closing? I don't even know if this unit is a vacuum operated one? I visited the trouble shooting section of the Vintage Air website but it didn't address this issue. Anyone have any suggestions? Thanks in advance.
