Power from the key goes to the A/C relay that when switched on applies
power to the resistor block allowing #1 speed when the blower switch is
off. Power from the key travels directly from the switch to the resistor
block, to the motor. The spped is controlled by which wire grom the
switch provides power to which resistor stack to allow each of the
possible speeds. #4 speed is direst to the motor. It sounds like the
motor has gone belly up. Everything you need to gain access to is
enclosed in the heater box.
The goal when driving is to miss the maximum number of objects.
