Check to see if their is power and ground at blower motor with test light. It is located under glove box area.you can make a test light with a tail light bulb and two wires. If no power the fan resister, fan switch, fuse or wiring is bad.

Hi i bought 2002 nissan sentra ..previous owner replaced head gasket ,water pump.thermostat ...car was running good for a week then sudeny no hot air inside(blows but cold) and 10 minutes later...


Thermostat is the wrong temperature range for the vehicle or it is installed backwards. It is opening too soon and not allowing the vehicle engine to come up to operating temperature soon enough. Have system checked, replace thermostat with correct temperature for vehicle

Previous owner installed a tempurature contol are


Your heater door cable is maladjusted.I would start be removing the heater control and follow the cable to the door it controls. See which end is adjustable - it will have a small screw and a holder.

I would push the lever to full cold and then loosen the cable and let it slide until the lever maxes out in the cold spot on the controller and then tighten again. Test its operation a few times before reinstalling everything.

1996 Sentra wont start. Replaced the battery. Turns over strong. Smells like it has fuel. Previous owner just replaced spark plug wires and distributor. Any suggestions?


If you smell fuel, there is a chance that the engine is 'flooded' and fuel has wet the plugs. You can dry it out to some extent by pushing the accelerator slowly to the floor and holding it there while you crank the engine. If it still won't start (or at least fire a couple of times) then you may not have any spark to drown. If it does sputter a little, continue holding the pedal down and continue cranking to see if the other cylinders will follow. It's time to pull a plug wire, place it on the block or other grounded surface and have someone crank it to see if there is any spark at all. If not, there are too many things that could prevent it so you may have to have the computer scanned to see what might have failed.
