on my 95 I have a 30 Circuit breaker that controls power to the blower motor, so the first thing I'd check is power at the Dark Blue (atleast that's the coler on 95s) wire when the key is in the on position. If you do, then that rules out any issues between the battery and the motor it self. At that point I'd jumper a wire from the hot side of the motor to a 12v soruce, and cround out the other terminal, if the fan work then that rules out the motor.
All the would leave is the resistior pack (Does the blower work on any of the settings? such as high?) or the climate control panel or the wiring in between.
Lots of times the power connector on the blower motor will overheat and either burn the wires or connector to the point the blower will not work, but usually it will stop working 1 or 2 speeds at a time, not all at once. I've had to replace that connector on my dad's '94 Escort 3 times for that reason. Everytime he tells me the blower isn't working that's the first thing I check and so far that has been the problem everytime.
