Under dash board on passenger side.
The 1991 Honda accord blower motor resistor is located on the firewall in the engine compartment. The blower motor resistor will be on the passenger side of the firewall.
Blown fuse, defective blower motor, defective wiring, defective blower motor resistor pack, or in rare instances a defective blower motor speed control.
The problem is either the blower motor resistor or the blower speed selector switch.
The blower resistor gets overheated and burns out usually because the blower motor is failing also.
toyotas have a resistor bank in line with heater motor each speed has a different value resistor. there is no resistor on high speed. it is located on passenger side in heater duct I thank it has two screws holding it on when you get it out you will see the resistors burned
Many are in the air duct near the blower motor.
It will be either defective fan switch, motor itself, blower motor resistor pack, blown fuse, or defective wiring. If the blower runs on high but no other speed, suspect the resistor pack.
The heater blower motor can be found beneath the passenger side dashboard. Remove the wiring harness from the back of the blower motor. Remove the blower motor retaining bolts. Reverse the process to install your new blower motor.
check the blower motor resistor located on fire wall behind washer fluid tank
blower motor resistor thermal limiter is blown. Replace the blower motor resistor.
In a 1991 Toyota Previa, the heater fan blower is located under the dashboard on the passenger side. You'll need to remove the lower dash panel to access it. The blower motor is typically mounted on the firewall, and you may need to disconnect electrical connections and possibly the blower motor housing to replace or service it.
Chances are that the blower resistor is blown. The resistor is located on the bottom of the blower, located in the passenger side footwell. If the problem is with the resistor them the blower will only work on high speed, other than that it might be a broken wire.
