#1 of 24 2002 Pathfinder blower motor resistor broke by romad293 Mar 15, 2007 (3:48 pm)
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.

Replying to: romad293 (Mar 15, 2007 3:48 pm) 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.

Replying to: pathstar1 (Mar 16, 2007 12:28 pm) 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++++)?

Replying to: nate240z (Mar 18, 2007 7:28 pm) 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. Replies to this message: nate240z (Mar 19, 2007 4:01 pm) jimmy76 (Jun 27, 2007 8:02 am) nate240z (Jun 27, 2007 1:09 pm)

Replying to: pathstar1 (Mar 19, 2007 7:02 am) 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. Replies to this message: jimmy76 (Jun 27, 2007 8:02 am) nate240z (Jun 27, 2007 1:09 pm)

Replying to: nate240z (Mar 19, 2007 4:01 pm) 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.

Replying to: jimmy76 (Jun 27, 2007 8:02 am) 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 24 2001 Pathfinder blower works only on High by tammi2 Dec 06, 2007 (10:36 am)
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 24 Pathfinder blower won't shut off by rtjr Jul 17, 2008 (6:03 pm)
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?
