Nope, time to get a new one.
first off there isn't a fan belt on the 99' so if your fan isn't working its a burned up motor, or the fuse has been triped.
Examine the back of the switch for loose or melted connections. Then examine the resistor for burned spots. In most cases a burned resistor is the result of a failing blower motor. So if a new resistor burns out in a short time, replace the motor also.
My 1991 has blown 3 resistors on the fan so far. Check the wiring harness near the fan. The resistors are within the connection. But you'lll see burned plastic if that's the trouble.
It is the fan speed module located on the shelf where the windshield wipers are. You have to either disconnect the fan motor plug or lift one of the battery terminals. The fan motor draws appreciable current so with out the engine runn ing it will soon drain the battery.
the fan is work by the elactercity and current and it has motor so i have to switched on and off

You don't say what vehicle or what type of fan so: Viscous Fan, fluid leaked out of coupling. Electric Fan, Fan motor burned out or brushes worn out. Fan relay failure, Fan Fuse failure, Temperature switch, in the radiator? failure (very common). With the ignition on short out the switch connector socket and see if the fan starts. If it does it's a switch fault. If not, start with the fuse then check the fan relay before condemning the fan.
Send it off to Microsoft so they can fix.
Probably a bad fan motor. Luckily, that is one of the easiest and cheapest things to fix on these cars. Open the hood and look by the windshield on the passenger side and there it is. Remove the screws, disconnect the wire and vent hose, and lift it out. The fan is attached so you have to transfer it to the new motor. Last one I bought was only $30 or so. VBdenny
Get a wire tester and start at the window motor. If it has electricity going to the motor, then the motor is burned out. No electricity, follow the wire to the switch (and so on).
The blower motor speed resistor is burned out. Keep in mind that in many cases the speed resistor burns out because the blower motor is failing and drawing to many amps. So if the new resistor burns out soon, next time replace the blower motor also.
Blower fan? Cooling fan? Check fuses Check to see if you are getting power to fan motor If so --bad fan motor If not -- does it comes on when A/C /defrost is on? Coolant temperature sensor?
