Does anyone know what blower motors fit a 1993 Civic EX? I am unsatisfied with the output and wonder if there is a bigger or one with more output that will fit the car. (Yes all 4 speeds work on the selector switch, I just feel there could be more oomph coming out of the vents)

 

You might have a bunch of leaves clogging the evaporator and/or heater cores. Removing the blower will let you see part of the evaporator.

Also make sure that full battery voltage is reaching the motor with the switch on high.

 

check the pollen filters behind the glove box also. they may be clogged up.

 

These older models don't have a pollen filter. The evaporator is your filter.
