AnswerTHE BLOWER RELAY IS BEHIND YOUR GLOVE BOX. REMOVE THE BOX AND IT WILL BE TO THE LEFT SIDE OF THE BLOWER MOTOR ASSEMBLY. LOOKS LIKE A CONNECTOR. HOWEVER, YOUR RELAY MAY NOT BE BAD EVEN THOUGH IT CLICKS. 9 OUT OF 10 ITS YOUR BLOWER MOTOR...

If you are talking about the blower relay for the fan motor because fan motor does not work, and you find out this is not the problem, I have a 1999 silverado where the fan motor stop working. Replaced the dash switch, did not fix the problem. Figured fan motor was bad. While attemping to remove the fan motor under the dash, there was a plastic cover attached to the motor which I removed and found a small circuit board that was showing a burnt spot. Replaced this circuit board first before going futher. This fixed my problem. Cost for the board from the dealer at the time (2005) was $30. Had I known about this board, could have save myself $165 replacing the dashboard switch.

The 1998 Dodge Neon does not have a relay. It does have a blower motor resistor that could be bad.

The high-speed relay is part of the blower resistor board, mounted in the air duct behind the coolant/washer bottles. Follow the wires from the blower motor, they lead to the resistor connector block that the blower resistor board is plugged into.

check for voltage at the blower motor on all settings. if no voltage check the blower motor resistor or relay. if it has a resistor it will be right beside the blower motor, if it has a relay it will be the relay on the firewall under the hood.it will probably have a purple,orange,blue,and black wires.

A 1998 Cadillac Deville does not have a blower relay. The system has a fuse and a controller to feed power to the blower motor.

The blower motor resistor is generally located close to the blower motor.

The 1998 Rav 4 blower motor relay switch is located in the engine compartment on the firewall. The blower motor relay switch will be on the passenger side of the firewall.

The resistor is to the left of the blower, it is very hard to get to. You'll have to almost stand on your head to change it.

Blower resistor is under the glove box. It is diamond shaped with 2 screws holding it in.

the resistor is gonna be right off the blower motor attached to the blower motor by a wire harness should be by the heater core

Well you got ten years out of it. Put in a new one. Fuse??? Take a test light and see if there is power to the blower. Had this problem on my 1998 silverado with blower working on only high speed. Replaced the resistor, relay, and motor. Didn't help. Finally decided to use a test light to check for power. Started at connection supplying power to the blower motor switch then checked for power at each blower switch speed connector. Bingo! Bad switch. www.napaonline.com/masterpages/NOLMaster.aspx?PageId=470&LineCode=ECH&PartNumber=HC1...

The blower motor resistor is located under the passenger side glove box by the foot rest, easily accessible with a standard ratchet.

The blower motor resistor is located on the lower right side of the HVAC unit housing inside the the vehicle under the dash on the passengers side........

The Blower Resistor is on the Passenger side of the car. Look under the glovebox to the right. There is a cap for the blower held on by 3(?) Screws. Pull this off. You will see wires going to the Resistor. Two screws hold in the blower resistor. See picture here. its #6 http://www.kiausaparts.com/catalog/results.asp?section=6150A&uid=610413&formname=sectionform

You have a bad blower resistor. it is located directly behind the blower motor on the passenger side of the vehicle. You must first disconnect blower motor from bad resistor. Lower and remove blower. It won't be easy but remove the screws holding the resistor, disconnect the resistor and remove it. Cost is approximately $40 for a new one.

Either it's the switch on the dash (unlikely) or the blower motor resistor pack (very likely). The resistor pack is usually easy to replace.

On the passenger side, bend under the dach, disconnect the coupler, remove the screw of the small hexgonal part and remove the blower motor resistor!

UNDER THE DASH ON THE PASSENGER SIDE. LOCATED ON THE BLOWER ASSEMBLY. LOOK UP TOWARD THE TOP OF THE BLOWER MOTOR. GIVEN BY STARBABYMAMA.

the blower resistor is located on the evaporator housing it is secured by two screws and has a 4 wire harness plug on it easily accessible you will see it as soon as you open the hood
