First, does anyone know of an alternative PN for a resistor other than the $$$ LR version?
Second, airflow.... This is an NAS 110 style dash with the blower vents, not the fresh air vent doors. The bulkhead already had the larger opening in it. On the engine side, I have a standard (non-A/C) box and blower set up. This saves room, is much cheaper, and there just isn't any need to have all that in the engine bay if you don't have A/C.
So picture this: The air comes through the bulkhead. It enters the lower dash, it is pushed through the dash and up into the center dash where the louvers point it at the peoples in the vehicle. Along the way, some of that air is directed either up or down--just like in normal Defenders. So, if you think about it, something like 1/2 of the air flow is ALWAYS going up or down, while 1/2 is always going out the vents. And what is really strange is that no matter what, the air temp coming out of the front vents is always 10-15 degrees warmer than the air coming out of the footwell vents, or defrost vents! What? It's all the same air coming out of the same box, through the same hole in the bulkhead!
Now, I'm sure the designers of this high tech system thought they would be generating laminar flow within the dark recesses of the lower dash body, but somehow I doubt that their design dreams are fully realized.
So the question is, other than a better fan, is there any way to increase flow through and around the obstacles and eddy current generators within the ducting system? And does anyone have any idea on how I might equalize the temps coming out of the vents?
