Could the blower resistor on my 1989 Dodge Dakota cause the AC not to work?

Possibly. A bad blower motor resistor would cause the blower motor to either not function or function only on one speed (usually high speed). The air conditioning system is probably set up such that if the blower isn't functioning at all, the air conditioner won't function. Otherwise the air conditioner would overheat.

Why would our 97 lesabre blower work sometimes and sometimes not?

If the blower motor randomly and intermittenly quits and does not work, chances are good the blower motor itself is faulty, if the blower motor does not work on all fan speeds from low through high, it most likely needs a blower motor resistor.
