Car Forum / Nissan / Nissan Cars / March 2006Blower Motor Problem
I own a 1997 Pathfinder XE. My blower motor works intermittently. Some days it does not run at all. Other days it works fine. Sometimes, it doesn't work when I start up the truck but after driving a few miles the blower will turn on. I took out the blower motor resistor and it was rusty and really worn. I ordered a new resistor and relay. Any other ideas? cried out > I own a 1997 Pathfinder XE. My blower motor works intermittently. > Some days it does not run at all.

Any other ideas? those are the first two things i would have checked, the relays and the resistor that is, next I would check the control sitch From what i know of Super Chargers (blowers) A roots type supercharger is commonly called a blower Roots superchargers are usually large and sit on top of the engine. They are popular in muscle cars and hot rods because they stick out of the hood of the car. However, they are the least efficient supercharger for two reasons: They add more weight to the vehicle and they move air in discrete bursts instead of in a smooth and continuous flow. So if it's working intermeittently or seemingly It eaither has a broke gear or it's not broke at all. > From what i know of Super Chargers (blowers) A roots type >supercharger is commonly called a blower Roots superchargers are [quoted text clipped - 5 lines] >intermeittently or seemingly It eaither has a broke gear or it's not >broke at all. WTF does a supercharger (Roots, lysholm/twin screw and/or centrifugal) have to do with the BLOWER MOTOR for the OP's ventilation system??? I took off the glove box today and unscrewed the blower motor. I can find the blower motor resistor but where is the blower motor relay? cried out > I took off the glove box today and unscrewed the blower motor.

One of the fuse boxes, either under the hood or under the dash, refer to your owners manual if possible to find the exact relay number I took off the glove box today and unscrewed the blower motor. I can find the blower motor resistor but where is the blower motor relay? >I took off the glove box today and unscrewed the blower motor. I can >find the blower motor resistor but where is the blower motor relay? While it's off take the cover off the bottom, undo the screws that hold the motor end cover on and remove the end cover. Check the brushes and commutator. If you have a pollen filter you won't have this problem. http://www.imagestation.com/picture/sraid203/paa345c93d17cb0e5add723d6470b51b9/e fac005c.jpg Rotor at top is scrap as commutator worn past recovery. Brushes are on RHS, worn very short. It's end cap and the whole brush space was choked full of chaff. Replacement secondhand fan's rotor at bottom, it's brushes at LHS and chaff in this one's end cap in centre. Caught it just in time. Nissan fitted a hose between outlet duct and commutator end of motor. It's to allow the fan to suck cool air though the motor but drags finely chopped chaff into the commutator. -- Peter Hill Spamtrap reply domain as per NNTP-Posting-Host in header Can of worms - what every fisherman wants.
