Re: AC Fan Motor Goes Off and On
There is a wire connector repair kit available at your local dealer. You may also need to replace the resistor module due to the connector being melted in the cavity. The heat is a result of a loose connection (high resistance) that eventually melts the connector to the module. Hope this helps.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

The rotary control switch on the dash controls the blower motor for the A/C. The A/C will not turn on unless the blower motor is functioning properly. The passenger-side radiator fan will not turn on until the A/C begins running. BUT the driver's side radiator fan should always work. Ergo, check the function of the blower motor (located underneath the dash behind the glove box). Usually when it goes bad, it's because of the blower motor RESISTOR (mounted inside the blower motor housing). When the resistor goes bad, the blower motor shorts out, causing it to fail. The switch rarely ever fails. The radiator fan relays are located next to & on both ends of the radiator. Check them too. In the link, the blower motor RESISTOR is #5.

Check to see if the connector that goes to that fan motor is tight, and that the connector prongs are not burnt. It may be the fan motor is shot! Next check the fan relay switch. They usually hide these near the wheel well.
It has a blower motor speed control resistor or module, it is located right next to the blower motor under the dash in most cars and one end of the resistor goes into the air ducting for cooling and the other has the electrical connector on it.
Sounds like your heater/bower motor has an issue. Behind the glove box door is your heater motor, and mounted to it is a heater motor resistor. It will have a wire harness plugged into it. These go bad, and you will loose low speeds.
The blower motor fan is controlled by the blower motor resistor.Its the resistor which controls the fan on respective speed which you select.But if the resistor goes faulty,then it will not be able to set the required speed which you set for fan,so it works on high speed only.
In this case you will have to replace the blower motor resistor.
Check fog for the location of blower motor resistor location:--- see part number 8 in the diagram below.
The blower motor resistor is located next to blower motor under the dash.Its fitted with 2 screws and a wiring connector.You have to remove the screws and wiring connector and take the resistor out and place the new resistor in same position and connect the connector as well as screws.
this should help.Thanks.Helpmech.
if you are talking about the engine electric cooling fan..it will run after car is turned off until temp goes down then it shut off..unless you're talking about the heater blower motor..then i would look in the engine compartment passenger side firewall for the heater box ..on the box there is speed control resistor for the heater fan speed..that might be shorted.if not fan switch on dash..give more info next time..it makes it easier answer with more info
that sounds like the blower motor resistor. on high it bypasses the resistor for maximum speed. but on low or medium speeds, the resistor slows down the blower motor. when the resistor goes out, the blower motor will only work on high. it is an inexpensive part and easy to replace. it should be located on the black box under the dash on the passenger side. there might be a plastic cover over it, but it will have a 3 or 4 wire connector plugged into it
The blower motor resister is located next to the fan under the passenger side dash. You will have to remove the glove box and plastic cover under the dash to expose the blower motor. the resister is next to the blower motor.
