It might be your resistor, does it work on 4 but not on 1,2,3? If so, you need a new blower motor resistor.
One can replace blower motor resistor on 2003 Nissan altima by removing the old using spanners and replacing it with a new one.
I actually have a brand new blower motor for a 2002 Nissan maxima. Its brand new, I bought it from Sandy Sansing Nissan in Pensacola, Florida thinking I needed to replace it, but it was actually my fan control amplifier that needed replacing. So if you need a new blower motor, I can ship you a new one for a bargain. I paid 219.00 for it, I'll let it go for 100.00. Email me at ebonysailor@yahoo.com
The car is to new to have it done yourself, you must take it to your nearest Nissan dealer.
To change the blower motor resistor in a 2002 Nissan Maxima, locate the blower motor resistor under the glove compartment on the passenger side of the vehicle. There is a clip that is depressed and then the resistor will slide out. Remove both ends of the resistor and then replace with the new resistor.
* Disconnect the negative battery cable * Remove the glove compartment and lower dash trim to gain access to the heater case and blower motor * Detach the blower motor cover and disconnect the electrical connector from the blower motor * Remove the blower motor mounting screws and pull the blower motor carefully out of the housing * If you are replacing the motor detach the fan and transfer it to the new motor
you need a new blower motor resistor
If the blower motor in your 2000 Nissan Maxima only works on the high setting, the issue is likely a faulty blower motor resistor. To fix it, you should first disconnect the battery, then locate the blower motor resistor, usually found near the blower motor under the dashboard. Remove the resistor and inspect it for damage or burned connections; replace it if necessary. After installing the new resistor, reconnect the battery and test the blower motor to ensure it operates on all settings.
To replace the blower motor resistor on a 2007 Nissan Quest, first, disconnect the negative battery cable to ensure safety. Then, locate the blower motor resistor, which is typically found under the dashboard on the passenger side, near the blower motor. Remove the electrical connector and the screws securing the resistor in place, then replace it with the new unit and reassemble everything. Finally, reconnect the battery and test the blower motor to ensure it operates correctly.
Locate the resistor under the dash attached on the blower motor housing. Disconnect the wire harness connector. Remove the resistor and install a new one.
To replace the blower motor resistor in a 2008 Nissan Sentra, first disconnect the negative battery terminal to ensure safety. Locate the blower motor resistor, which is typically found under the passenger side dashboard near the blower motor. Remove the electrical connector and unscrew the resistor from its mounting. Install the new resistor by reversing the removal process, reconnecting the electrical connector, and then reconnecting the battery.
I do not know what vehicle you are referring to but I just replaced one on a 1996 Nissan Sentra because the only speed that was working on the blower motor was 'high'. Underneath the glove box was a couple of screws that came out and the new resistor was put in. Two screws and done......... Most blower motor resistors are located close to the blower motor.
To replace the blower motor in a 2005 Nissan Quest, first disconnect the negative battery cable to ensure safety. Remove the dashboard trim panel and the glove compartment to access the blower motor assembly, typically located behind the dash on the passenger side. Disconnect the electrical connector and remove the screws or bolts holding the blower motor in place, then carefully take out the old motor. Install the new blower motor by reversing the removal steps, ensuring all connections are secure before reassembling the dashboard and reconnecting the battery.
