It can. Could also be the fuse or the motor itself, the switch, relay.
Blown fuse. Burned out blower speed resistor. Faulty blower switch. Bad blower motor.
The Blower resistor should be tested which is located near the blower motor, the resistor is probably faulty.
faulty blower motor resistor
Assuming you're talking about the blower motor, because the blower motor resistor is faulty, and needs to be replaced. On the high setting, it doesn't go through the resistor - on the other settings, it does.
To test the blower motor resistor, unplug the resistor connector. Each blower motor switch input terminal on the resistor must have continuity to the resistor output terminal, which is connected to the circuit going to the blower motor. If the blower motor resistor continuity does not check OK, replace the faulty resistor.You need a multimeter to test the resistor block and there should be continuity between all terminals.
The issue may be caused by a faulty blower motor resistor.
It could be due to a faulty resistor in the blower motor circuit. The resistor regulates the speed of the blower motor, and if it malfunctions, the high speed setting may not work properly. It would be best to have a mechanic inspect and replace the resistor if necessary.
That is a typical sign that the blower resistor has gone faulty
You can determine if your blower resistor is faulty by checking for inconsistent fan speeds or if the blower motor only works on certain settings (usually high speed). Additionally, if the blower motor doesn't operate at all or if there’s a burning smell, it could indicate a bad resistor. Testing the resistor with a multimeter for continuity can also confirm whether it’s functioning properly. If these signs are present, replacing the blower resistor is often necessary.
The control switch is probably faulty (or faulty wiring to the switch and/or motor). the resistor unit must be open cicuit that is mounted in the air duct near the blower usually
If the AC blower on a 1999 Ford Contour only operates on high, it's likely due to a faulty blower motor resistor. The resistor controls the speed of the blower motor at different settings, and when it fails, the blower may default to just the highest speed. Another possibility could be a malfunctioning blower motor switch or wiring issue. Checking and replacing the resistor is often the first step in troubleshooting this problem.
On a 2007 Nissan Frontier, the blower motor resistor is typically located under the dashboard on the passenger side, near the blower motor itself. It is usually mounted to the HVAC housing. If the blower only works on high, the resistor may be faulty, as it controls the different blower speeds. To access it, you may need to remove a few panels or the glove compartment for better visibility.
