Could be a bad switch or a ground fault. Unclip the wires(or terminal) from the switch and inspect the plug for a short. Replace the fuse and turn the ignition on with the switch unplugged. If the fuse still pops there is a ground fault somewhere else in the wiring.

Did you check all fuses after replacing everything? If you did not disconnect battery while replacement you may have blown fuse.
Good luck.

SOURCE: Replacing heater blower motor

this is not a problem with thw switch or motor. There is a resistor that is mounted inside the dash on the pasenger side that controls the speed of the blwer..these have a tendency to burn up after 10 years or so... replace the resistor, and you will be fine!  http://cgi.ebay.com/ebaymotors/Toyota-Truck-A-C-Heater-Fan-Resistor_W0QQcmdZViewItemQQcategoryZ33548QQihZ016QQitemZ260344846266QQrdZ1QQsspagenameZWDVW#ht_500wt_1230

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.

Heater fan has sto pped working. The car still lets heat in the cabin when control is turned up. Blower is not wotking. 2008 VW Rabbit.


First look to see if you have a fuse for the blower motor...then you will want to disconnect power to the fan an jump 12 volts to the fan motor to see if it works...if ok, then there is a speed control resistor that sometimes goes bad located on the heater assembly...It is usually right past the fan so the fan can keep it cool and has 4 or more wires on it. if all else ok then last would be the switch inside car

2000 Ford Taurus - A/C fan only works on high; cool air is "available" but not blown as fan won't run, except in "high" position. Any suggestions?


The low speeds(all of them) are distributed threw the fan speed switch to the blower motor resister.The resister is the problem.It is located very near the blower motor.It has two screws mounting it to the blower box.It has a plug in with about 5 to 7 wires.Unplug this plug to the resister.Remove the screws.Pull the resister toward you,it mounts and rest inside of the blower case,this is how it is cooled.Now when you replace the resister,replace the blower motor.Even if the bower motor is running fine, it is pulling to many amps for the resister.It will happen again soon,if you don`t replace the blower motor.If I can help you any more,please let me know.

most likely you have a very bad ignition switch, the only other pathway for switched acc. to operate when key is off is if someone has had the wires feeding the fuse box crossed. so unless you had recent wiring done by an amature, you need and ignition switch. after replaceing you may still need to replace some fuses or bulbs that didn't like being powered at the wrong time.

Fan motor keeps running on Audi A4 2004


fan motor has a thermal switch which turns on the fan as soon as the engine heats up. what happened there is that the switch is stuck on the closed position which keeps the fan on all the time. you should go to a garrage and have the part changed.

94 tracer problem


not sure about the popping thing, but about the fan, try hot wiring the fan motor to the battery to make sure the motor is not burnt out. could also be a relay or a fuse link. I'm working on a 95 and having trouble locating the fuse links. I replaced my radiator fan motor, thermostat was busted, dropped new fuses in and a relay. Still no fan action. Mine must be a fuse link. If you are lucky it will be something quick to diagnos. Good luck.
