Hi, I ran into a similar problem with my 08 Xterra X 2008. The AC blower doesn't turn on at all, no matter what the blower speed setting is. The AC light on the dashboard turns on when the speed setting is at 1,2 and 3 and turns off when the speed setting is at 4. I hear a click sound under the hood when the fan speed is turned from 4 to 3 or from off to 1.
Do you think it is a resistor problem? If this was the resistor problem, i think the fan shld have worked at some speed setting, right? Any help would be appreciated. Thank you, |

Start by inspecting or changing the Blower Motor Relay. If the relay is OK, then you may have to bad blower motor. Usually when the blower motor doesn't work at all or at time, the problem is the blower motor itself.

Does it have auto climate control? If so, you probably have a bad fan blower control amp. When the fail, the default to constant "on" and at the highest speed.

Now I'm confused on what to actually look for. I know the blower motor and blower relay. Is there a difference in a VBC (variable blower control) and a blower resistor?

So looks like there is no power supply to the relay. Checked the fuses in the fuse boxes with a multimeter and they are all fine. There are 2 fuses for Front blower and exchanged them with other 15 AMP fuses in same box, but no luck. Do you think it could be the wiring thats gone bad? I couldn't find the electrical diagram for the Xterra AC system. What do you think could have gone bad? |

I replaced the resistor and put it all back together and it still worked intermittently. I returned the resistor and replaced the motor and that worked for the rest of the time I owned the truck. I think the motor worked on the bench because I was holding it sideways. When it was mounted vertically under the dashboard it didn't work so I think it was the brushes just made contact at the right angle.
