As it's an older car maybe the fan motor brushes are worn out, otherwise could be a coolant sensor internal fault or wiring fault somewhere. You need a wiring diagram so you can understand how power feeds fan and what switches it on/off, then you can look for a solution.

Intermittent charging


Sounds as if the voltage regulator is going bad. Most are now located on or inside the alternator itself. Passing the test with the problem being intermittent makes a case for the regulator. I suggest getting a regulator, or replace the alternator with a friends if you have one whose model will fit.

A good day to you..i had this problem abot 5 days now.i had 95 nissan sentra the aircon is working fine but the fan goes on and off .i had suspected that a small board which connected to the fan speed...


Its called the blower motor resistor!! This controls all circuits to the blower motor (a/c fan) and regulates speed according to the switch/fan selector. Some issues caused from a faulty resistor may include: some or all fan speeds don't work, fan cuts out, no power or intermittent power to the fan motor.

Seems like a faulty voltage regulator, or that the wiring between regulator and alternator output is working intermittently. Before fiddling with the voltage regulator, clean the alternator plug, located on the opposite end of the pulley/belt. After cleaning, plug and unplug a few times, to insure a clean, solid contact.

Check and see if you have power to the blower motor regulator. It is located behind the glove box.

I have a 2003 Jeep Liberty. The radiator cooling fan stopped working and the car almost overheated. I replaced the relay with the new style with the cooling pins and the fan now comes on, though...


no but there are a couple of cooling fan switches that could be causing your problem both are mounted on the motor one near the thermostat housing the other will be in the block one near the thermostat usually controls the fans.
