The relay for the blower motor might be stuck , or the switch is bad . I have a 1983 Oldsmobile 88. A few days ago the blower motor for the A/C, Vent, Heater kept running after I turned off the ignition and got out of the car. It is located under the front hood in the engine compartment against the firewall. I went into the store and when I returned it was still running. Later that day the A/C stopped working. Well it wasn't the AC it was the blower. It didn't work on AC, heater, or vent. The manual I got at the autoparts store indicated a couple of relays under the hood, under the dash on the right and left sides, and fuses also. I swapped all the relays to find out if it would start working and something else would stop but the blower still would not run. The next day I went outside to find the blower was running when I walked up to the car. I started the engine and the a/c worked fine. I disconnected the blower plug under the hood to prevent the battery from going dead. So I have two problems. The blower running with the engin off, then it not working at all for two days. If anyone has had a similar problem please comment. Also where specifically is the blower relay. I don't think I have found the correct one. Thank you, Mark
For the 1989 Dodge Ram, the heater blower motor resistor can be found on the passenger's side, on the bottom of the heater box. It is beside the blower motor.
Blower motor is located on the firewall behind the engine.
Under the hood to the left of the blower motor mounted in the housing on the firewall...
Only for the high speed. The lower speeds are controlled with the use of a blower motor speed resistor.
Either the blower motor fan switch is bad or the blower motor resistor pack is defective. It is more than likely the blower motor resistor pack.
The 1989 Honda Accord blower motor relay switch can be found on the firewall in the engine compartment. The blower motor relay switch will be on the passenger side of the firewall.
the blower motor is behind the glove box under the dash
Might be a bad heater control
Replace blower motor resistor usually located in the duct work or out in engine compartment in ductwork by heater motor.
under the hood on the passenger above the blower motor mounted to a bracket.
the blower moter is located just behind the battery in the black boxor on the black box
Could be, heater blower motor has failed. blower motor fuse is burned out. blower motor speed resistor is burned out. blower motor switch is bad. or, if the blower motor works but you have no heat it could be, cooling system is low on coolant. thermostat is stuck open. heater core is plugged. temp blend door actuator is faulty.
Inisde the dash, passenger side.
Check blower motor fuse Check to see if blower motor is getting power
Ifit has the c68 option (auto air) check the blower control module under the hood
it is next to the firewall near the heater coil
Answer 1. blown fuse 2. broken wire 3. broken heat sensor (on side of heater housing, inside car) 4. burnt wires 4. bad blower motor speed resistor 5. bad blower motor 6. bad blower motor switch
It is inside the HVAC housing behind the glove box.
Check for a blown fuse. If the fuse is good then apply 12 volts directly to the blower motor. If it runs then the Blower Motor Resistor Pack is defective. If it does not run the motor itself is defective.
The most common problems will be with either the power or the ground going to the the blower motor.................
It could be the relay
It is inside the HVAC housing, behind the glove box.
unplug the blower motor (electrical) Unbolt the blower moter Remove the alternator Remove the top powersteering bracket bolt Loosen the lower powersteering bolt Pry the powersteering pump towards the front of the car as much as possible Have a freind pry the engine towards the front of the car while you rotate and turn the blower motor out of the housing. Caution do not bend the fins on the blower motor. Its a tight fit but will come out with the right angle
On the right hand side of interior bulkhead under glove box.
under the coil packs which are located at the rear of the motor on top
