You can find a wiring diagram for a blower motor resistor in the owner's manual. You can also check with local supply stores.

Can't give you a diagram but the blower speed resistor is under the hood, on the passenger side firewall not far from the blower motor in plain sight.
Possibilities: blower motor, resistor, wiring, control in dash
Look under your glove box and locate the wiring coming out of of the blower motor. This wiring connects to more wiring coming out of the heater/ac ducting behind the glove box. That connecting wiring comes from the blower motor resistor. It is held in place by two screws, one on each side. Remove those screws and the resistor will slide out.
To repair the blower motor resistor on a 1989 Buick LeSabre, first disconnect the vehicle's battery to ensure safety. Locate the blower motor resistor, typically found near the blower motor under the dashboard on the passenger side. Remove the wiring connector and the screws securing the resistor, then replace it with a new unit. Finally, reattach the wiring connector, secure everything back in place, and reconnect the battery to test the blower motor.
To replace the blower motor resistor on a 2001 Hyundai XG300, first disconnect the negative battery terminal to ensure safety. Then, locate the blower motor resistor, which is typically found near the blower motor under the dashboard on the passenger side. Remove any necessary panels for access, disconnect the wiring harness, and unbolt the resistor from its mounting. Install the new resistor by reversing the steps, reconnect the wiring, and test the blower settings to ensure proper function.
Fuses and relays are not your problem. The Blower Motor Resistor Pack is defective and needs replacing.Fuses and relays are not your problem. The Blower Motor Resistor Pack is defective and needs replacing.
A malfunctioning blower motor resistor will cause the blower motor not to work. When the resistor is bad the blower motors will not turn on.
First check the fuse to see if it is blown. If the fuse is good, then it is either the blower motor switch, blower motor Resistor Pack, or the Blower Motor itself. It can also be bad wiring. Apply 12 volts directly to the blower motor to see if it is good. If it is good and the wiring it OK, then it is the switch or resistor pack. I would bet on the Resistor Pack being the culprit. The switch rarely goes bad..
Depends on the year. You could try the resistor first since it is the cheapest. If not that, then check the fuses, relays and wiring to the control head. Then lastly, change the motor.
