Heater Blower Output
Replaced blower motor and refurbished the heater box. All vent and defroster controls work fine but even on high the amout of air doesn't match a new car. Is that customary with these older cars?

Well, I get 3 speeds. I replaced the switch, blower motor, and resistor. Just don't get a lot of air thru the defroster or vents. I cleaned out and refurbished everything. Maybe I'll put the old resistor back in and see if that makes any difference.

I think the plenum is the black piece that the hoses connect to that go to the defroster? If I'm right it's made of plastic and appears to be fairly new. Still had the price tag on it. If I connect one of the wires coming from the blower in the engine bay to battery (-) and the other wire to battery (+) to see if motor speed is affected, does it matter which wire goes to (+)?
