The A/C is blowing cold air but why is the blower weak?


Check that you have the selector set to blow out the vents and not the defroster or the vents by the footwells. Does it sound loud like it should be blowing strong or is it weak? The selector 'doors' under the dash work off of engine vacuum lines. If they won't 'select' when you change the knobs, there may be a vacuum line leaking. Also, make sure the blower motor is not all clogged up with leaves and debris.

The blower motor resistor has to be changed. The part is in the wirng between the a/c control head and the blower motor.

Air flow weak when set to heat


check for dirty cab air inlet or "HVAC" filter, or heater core is plugged from debris and air is being restricted and wont blow through. it works like a radiator, air ducts can also be getting stuck.
