I just put a complete a/c system in my 76TA. I probably never noticed it before, but I can hear the fan blowing, but there isn't much air coming out of the vents. It's the same on defrost or heat, but it does blow to each of them as directed by the controls. I'm wondering if it's not getting enough air in, but where is the intake for the a/c system? and is there any easy way to determine if the door/flap from the evaporator is opening all the way? Or a good vent flow diagram. Thanks!
