on the right side of the engine firewall on a relay brackt. which one?
Heater blower relay if there is one... There are relays underneathe steering wheel but right next to driver door. And in engine compartment where shock is on drivers side.
In the engine compartment. Center of the firewall behind the engine.
If your standing in front of the car looking at the engine there is a fuse box on the fire wall on the passenger side and the relay is in that below the fuses when you remove cover. The blower motor resistor/power module is under that fuse box on the left hand side of it near the silver A/C tank.
it's the blower motor
The horn relay on a 1991 Oldsmobile Cutlass Cierra is located on the passenger side firewall inside the engine compartment. It is just to the left of the blower motor assembly.
it's bolted to a bracket in front of the motor, between the motor and the fans, slightly to the left.
Open the bonnet, remove the scuttle cover, wiper motor, and finally blower motor.
faulty blower module. Under hood not far from blower motor
You can find the 1991 Nissan starter motor relay switch in the fuse box. The starter motor relay switch will be in the third column, second from the bottom.
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.
The blower motor is located on the passenger side up under the glove box.
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.
fuse #5 on the relay panel on firewall left and above blower motor.
On the back side of the fuse box the relays next to the first 2 on the left are the a/c blower motor relay & a/c control relay. The one on the far right is the warning buzzer & a/c compressor relay
Behind the power steering pump on the passenger side.The pump will have to be removed in order to remove the blower motor.
Many are in the air duct near the blower motor.
Blown fuse, defective blower motor, defective wiring, defective blower motor resistor pack, or in rare instances a defective blower motor speed control.
Under the dash on the passengers side................Disconnect the negative battery cable.Remove the 4 retaining screws and remove the right side instrument panel sound insulator.Disconnect the blower motor electrical connector.Remove the right side hinge pillar trim finish panel by pulling it away from the front body hinge pillar.Remove the screw from the secondary ECM bracket and swing the ECM module and bracket aside to provide access to the blower motor.Remove the blower mounting screws, leaving the screw closest to the relay for last. Carefully lower the blower motor fan assembly and remove.
The blower resistor gets overheated and burns out usually because the blower motor is failing also.
look on firewall on passinger side
If an automatic window will fail to lower on a 1991 Honda Accord than the power winder motor or relay can be the problem. The easiest place to check is the relay. If the relay is fine than the motor is failing.
The blower is common to hot and cold air. If it is only cold air that is a problem, then the problem is not the blower motor. The blower motor is actually in the engine compartment, passenger side at the firewall.
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.
Replace your heater selector switch
