Why does the heater in my 1999 dodge 1500 go from floor to dash when I accelerate? It sounds like the fresh air door opens and then shuts when I let off the gas? I also noticed that my transmission doesn't shift up as fast since this started? I don't know where to start looking for a vacuum leak?
have the same problem?
