My fan would not turn off...it constanty blows in high mode. I know it is the resistor for the blower motor but I cannot find it! It is kind of embarassing considering that about 5 years ago I worked in a Nissan Dealership as a service tech...I just never performed this maintenance on this vehice.I cannot find where it is to replace it. Hopefuy someone can expain where to find it.Any help is appreciated.

It's a fan control amplifier (a power FET), not a resistor. It appears to be on top of the fan plenum just to the left of the fan. Yours must be shorted (the power FET). Zapped or something - perhaps heat damaged it. It's right behind the upper left of the glove box.
 
Have fun. ">

I developed the exact same problem this morning. Is this Fan Contol Amplifier the same part listed as the Blower Motor Resistor elsewhere ($35-ish) or is this going to be a dealer-only part ($100++++)? Thanks-

I have the "ESM" (Electronic Service Manual) - a CD. It doesn't show a blower motor resistor, either in the pictorials or the schematics. It shows the Fan Control Amplifier (which is drawn as a power FET). The Fan Control Amplifier is shown in the spot you would expect a resistor in older designs (from fan motor to ground). It is controlled by the climate control chip.

While you have provided me with the answer to my question, It's not what I wanted to hear... oh, well I guess the wallet is going to be a little bit lighter now. Thanks for the info.

My fan just started doing the same thing, I can't shut it off and it's on high. I have a 2002 Pathfinder, I just got a quote for the Fan Amp, it's $261! It's a dealer only part... you know it costs them about $1 to make it in China. Aparently this is a common problem with the Pathfinders... Hope that helps.

Jimmy-
Check the salvage yards... mine was purchased for about $25 and then I traded the Pathfinder in on an '07 Frontier CC LB, which is what I wanted to begin with... good luck.

Was wondering, if my fan runs but it is surging and/or makes a "whooshing" noise could this be the same problem? Any help would be appreciated.

#9 of 34 2001 Pathfinder blower works only on High by tammi2

Doesn't matter where I want it to blow, but the heat/clim control only comes on when the blower's on the highest setting. Help! What's wrong, and how do I fix it?

#10 of 34 Pathfinder blower won't shut off by rtjr

I have a 2001 Pathfinder and the fan doesn't stop blowing even when the ac is off. It does go to different speeds when the ac is on, but when I cut the ac off, it still is blowing, but not as fast. Any suggestions?
