Hi! I'm new to the site and have the same problem with my "new" 99 Sentra GXE. Only the high setting works. Does anyone know what the Resistor values are if I wanted to replace the high power resistors myself ?

I don't think its possible if the unit looks like the one in Post #13. The resistors are built into the blade that sits inside the blower unit.
1994 Nissan Altima climate control only works on high...
Hey everyone, I just picked up a 1994 Altima and ran into the same issue with the fan for the heat and air, it works but only on high (#4). I guess my question is should I start with finding a new resistor, or a new climate control panel for the dash? A buddy said it is going to be one or the other as when it is on high, it blows like nobody's business, but thats it all or nothing. This is my first Nissan, so any suggestions would be great, also trying to keep the cost down as this is a back up car and I don't want to spend a fortune on it. Thanks in advance.

I'd try the resistor unit first .... 99% chance that it's the problem. It's also the cheapest. NAPA actually sells one for the Altima -- $42.
I replaced the resister because my fan only worked on #4 setting. I drove down the road and after only 20 minutes of operation on #2 fan motor setting, it went out again. Now the fan only works on the #4 setting. Did I get a bad fan resister, or is it a sign of a bigger problem. Is it possible that the motor over draws the fan resister, or I have a short somewhere in the dash. Should I just buy another resister and see what happens. At this rate I will have to buy them by the case.

From the sounds of it you certainly could have an electrical problem (higher current draw that over heats the fan resistor) causing the resistor to burn out. I'd try and investigate the circuit further before throwing another resistor unit in the car.
Check the connector that plugs into the resistor unit and make sure it's not corroded or dirty -- check the easy stuff first.
It seems that if you have manual A/C you will replace the blower motor resistor which looks like the photo posted in this thread. However, my 2005 Nissan Altima 2.5L has auto AC and according to the repair manual (which I downloaded off the internet), I needed to replace the blower motor amp (amplifier). This part is located in the same place as the motor resistor...on the passenger side behind the blower motor casing. It has a cable running to it and when you disconnect the cable it will reveal a silver cast metal shell with a clear plastic top that has 3 prongs that plug into the cable. I ran to my Nissan dealer and purchased what the parts department referred to as a Module Assembly Part# 27761-2Y000 (high-tech term for the blower motor amp) for $77.00. Probably could've found it elsewhere for cheaper but I wasn't willing to shop around. Anyway, I plugged the new part in, replaced the two screws and voila! Worked like a charm! Good luck to all of the other single mom's on a budget like myself who are willing to tackle this sooo simple job! Thanks to all of the others who posted on this thread. You gave me lots of guidance which lead me near the right direction.
