Auto A/C HVAC Fan only work on speed 4
I have a problem with my 2003 pathy that is listed in the bulletins. (Auto A/C HVAC fan only works on speed 4). I have 3 questions if someone can help me. First, if a bulletin is listed does the dealer cut you any discounts on repair costs? or Can I fix this myself if I'm somewhat handy? If I have to do it myself where could I find instructions?
Thanks |

Hello
1. Remove glove box. (See figure 1 for pin locations) 2. Remove the dash finisher and dash lower cover (See Figures 2,3,4,5 for clip locations) 3. With the lower cover removed, remove the 2 screws holding the the amp and replaced with new one. (See figure 6) |
Nissan Tech,
I replaced the control amp. You were right it only took a few minutes, unfortunately it didn't solve the problem. The fan still runs on high when in Auto or Econ modes. I notice that the temperature of the air is affected by the theromstat setting but it will only run full speed. Any other possiblities? |

Since I am using your instructions, I thought I should say thanks, also, I put the instructions into a PDF as I wanted to print it so it is in a one file. Can be found here, or in attachment. |
I have removed the glove box...
I am able to identify the area which correlates most to the diagram displayed above, and also the Relay itself...
However, it seems as though the resistor is made of a hard plastic which is fused onto the hard black plastic fan box... How does one remove this? Is that a cover, which I must remove first? I have already completely removed the glove box, and glove box assembly. Thanks |
I have a 1998 Pathfinder and my fan stopped blowing. IS it possible that leaves could make down to the fan assembly and impede the blade?
Thank you! |

Fan amp control follow up
just a follow-up. i replaced the module and everytrhing worked fine. :clap: One of the main causes of this module failure is failure to replace the IN CABIN AIR FILTER. Nissan originally stated to replace this filter every 30,000 miles or 1 year. However they changed the service procedure to 15,000 miles or 1 year. I didnt even know this car had one. :confused: I removed the filter and it was VERY dirty. :nono: I found evidense it had been changed 30 months ago, or 50,000 mikes ago.
