Could be the blower motor resistor is burned out as they do that. It's located after the blower motor on the side of the ventilation tube with a connector on the end.

When i turn off my heater or AC the fan keeps blowing until I turn off the car


The fan blower will work independently of the ac switch but the ac will not work unless the blower fan is switched on. It is possible that you have been using the one switch to control both with out realising what is going on.

I turned on the ac and the light does not work, the vents are not blowing and the car is running hot. I have a saturn SL 1996


First check the 15 amp HVAC fuse located in the main fuse block inside the car on the passenger side of the center console, under a cover. If the fuse is good, then the problem may either be the HVAC blower switch (which is the fan blower selector switch), the fan blower motor resistor, or the fan blower motor. An auto repair manual will explain and illustrate for you the steps on how to check each of these components.

Even after pushing the ac light switch on, the fan blower selector switch has to be turned on as well (working) because it provides an electrical path to the positive side of the battery to complete the circuit and turn the ac light on. What the ac light switch does is provide the electrical path for the ac compressor clutch to come on through the ac control relay which is controlled by the car's PCM(computer) when you want ac, but the ac light switch still needs to run through the fan blower selector switch to receive its power. You can turn on the fan without the ac light switch because it gets its ground path(negative) from the blower motor. So the blower motor has to work in order to provide a ground path for the fan blower selector switch to be functional. You could have a faulty blower motor which is why no air blows through the vents. The fan blower motor is located inside the car on the passenger side underneath the dash at the bottom end of the glove compartment box. You'll see it. It's right above where a person rests their feet on the floor. Therefore, if your 15 amp HVAC fuse is good, check to see if you have voltage at the blower motor connector. Unclip the connector and with the ignition on and the fan blower switch moved to any one of the first 3 selections, check for voltage using a multimeter. The voltage will vary because there is a blower motor resistor. Voltage should be higher on setting 3 than 1. If you do have voltage at the blower motor connector, check for a faulty blower motor. The auto repair manual will tell you how to do it using jumper wires.

It's normal that your car is running hot because the radiator fan works in conjunction with your ac compressor. If the ac is on, the radiator fan will be on and therefore the engine coolant temperature will stay in it's normal operating range. If the ac is off, the radiator fan will stay off as well and the engine coolant temperature gauge will begin to rise and show pretty hot (especially at idle). It will do this up until a certain degree then the radiator fan should turn on thermostatically and stabilize the temperature. It's scary and I know what your saying because it does that to my car if my ac isn't on. Don't worry it won't overheat.

The AC fan in my car (volvo s40-99) does not work


If you are talking about the blower motor fan,inside the car,look for a blown fuse,or a bad fan relay.The blower motor relay could be mounted near the blower motor,or in the relay box,look for the lables to guide you to it.If the relay,and the fan are fine,then replace the blower motor.

Subject: 2004 isuzu rodeo...my ac/heater blower is not working


The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.
