hey, About a week ago i had some problems with my hvac controls. Primarily the problem is the fan speed control (off, 1, 2, 3, 4) the fan only works when i put it on 4 or the highest setting. I turned on the ac with the fan on 1 and my idle rpm went on and then turned it off and the idle backed down as normal. I guess the system recognizes that it is on but only actually blows in 4. Any advice would be a huge benefit. Lights work fine as well. Thank you. ---

Had the exact same problem. It was the resistor. If you look at the i guess wiring diagram in the dsm its easy to figure out. I think its like 9 bucks at nissan iirc. 5 min job. edit: pg HA-39 in DSM. Controls 1,2,3 all go to the resistor while 4 doesn’t. That how i figured it out. and im a n00b with wiring… but sometimes the simplest answer is the right one. ---

my sister’s 95 had that problem, and it was fixed with a new blower motor… take the blower motor out (behind the glove box) and rotate it 90 degrees, her shitty motor worked on all 4 settings when the motor was sidways but not upright, I took the motor apart and the copper winding was VERY deeply grooved… among other tell tail signs of an old/weak motor… ---

Nope wasn’t the motor, just the resistor, 36 buks from nissan but o well. Guy at nissan said fairly common problem with sentra’s and some 240’s. All good now and works fine, thanks. Please lock thread
