I got a 95 Maxima SE with a Manual climate controller. The problem is that for some reason both the A/C and the heater work perfectly well, in all positions and settings except for the 1-4 power dial. Basically when I turn from OFF to 1 then 2 then 3, nothing happens as though I didnt touch it at all, however, when I reach 4 it turns on FULL BLAST.

I'm happy that it works in someway period, but I need some help to get the thing to work in the other 3 settings.


THANKS FOR THE HELP

 

Change the switch

 

Had same problem! Replaced resistor (on passenger side of airbox) for less than $20... fan blows in all settings!!

 

Yeah its the resistor, there is a write up for this problem in the stickies

 

Thanks alot, ima gonna get on it asap, will be back with details

 

http://forums.maxima.org/showpost.ph...2&postcount=31 I read through the stickies last night and found this

There is a resistor assembly mounted on the air duct close to the blower motor. That part has failed. It is used to control fan speeds 1, 2, and 3. Speed 4 is the maximum blower motor speed, so no resistors are involved. Replacing the resistor assembly is something the home mechanic can do. The only tool needed is a Phillips screwdriver. The replacement part costs about US$25.

The blower motor is located just above the passenger's feet. Look at the wires leading away from the blower motor. Just inches away from the blower motor there is an electrical connector located on the air duct. That's the resistor assembly. It is easy to remove and replace.

Replacement is the usual remedy. However, if a spot of localized damage is seen it may be repaired with a soldering gun.

There is a good photo of the blower motor and resistor assembly in the Haynes repair manual, page 3-8. If you don't already have a copy of this book, please get one. It will be money well spent.

a) Move the front pass seat all the way back (for convenience)
b) Remove a harness connector (with 4 wires I think) running into the bottom of the blower motor.
c) Remove the 2 philips screws that hold the blower motor resistor in place.
d) Put new one in, reverse install.

Blower Motor Resistor Part Number: 27150-1E405

You can get it here:

Should be $28 at your local dealer. It's $28 delivered from discount Nissan parts sites.


Edit: If you are handy with a soldering iron, you can try to fix it yourself. See this thread.

 

bye bye resistor

 

if i had read this sooner I would never have bought the stupid switch and stopped screwing around with the blower fuses.

Thanks I finally know what to do.
