Sorry to bring up an old topic but my 77 does the exact same thing and I didn't see an answer in this thread.


The fan switch does nothing, there is a constant light flow of air from the vents until you switch it to a/c (max) and it blows hard. However, it only comes from the dash vents, no floor or defrost.
