Probably not. First, check the blower resistor assembly. It's usually in the
blower box. At the low fan speeds it has to dissipate a lot of heat so they put
in the path of the air flow. Eventually those power resistor elements
deteriorate and open up. That's what causes the loss of some fan speeds.

The blower resistor on my '88 Prelude has one electrical connector on it and is
held in the blower box with two screws. Yours, like mine, probably has three
resistor elements.
