Where is the blower resistor on a 2001 Nissan Sentra?

Its actually not that bad to change. If you open the glove box and remove the screws then the screws along the bottom of the glove box at the bottom of the dash the box will slide out. Remember to disconnect the light if it has one. Now you will be able to see the underside of the dash. You can see a large black box that has wires and vacuum lines all over. You need to locate a small flat plate with two screws and a plug in the middle. Disconnect the plug and remove the screws. The resistor will come straight out. The back side will look like small coiled up springs of different sizes. Install in reverse.Hope this helps. Good luck. Please re-post with updates. Thanks cj2176.

Try removing the glove box door it may expose the resistor or get on your back to remove an access panel under the glove box some cars you don't need to remove anything just lay on your back and look up under the dash around where the heater box is and use a 1'4 inch drive rachet with perhaps a swivel end to reach screws
