There are several signs that you can look for to tell if your blower motor might be on its way out—for instance, if your HVAC blower does not operate at different speed settings or doesn't work at all, that could be a sign the motor is on its way out. That's all it took for for mine to start working again. To diagnose why the air conditioning in your car isn't working, start by turning your car on and setting the AC to full blast. It stopped working on a very cold day, my hands were freezing. the blower motor is below the glove compartment. In fact, even the diagnosis of a failed blower motor resistance is actually simple and requires no special skills or even basic knowledge, as the resistor serves only one purpose – to limit the blower to different speed settings. Let me know if this helps. If blower motor is good then with blower switch on high, test light on negitive battery terminal, check at the connector next to the blower motor. I would have to agree with the rest of these fellas, blower motor resistor. The 2000 Chevrolet Malibu has 31 problems reported for blower fan doesn't work on all settings. We used the word "fan" in the problem description because it's a more familiar term. Since it works on one setting, I assume the blower and everything is mechanically sound, which implies there's some sort of electronic issue: is this likely something simple like a burned fuse or the knob not … Using a test light or a multimeter set on volts, unplug the blower motor. Not the 3rd setting doesn't work, only the last/highest. The blower motor relay supplies power to this motor when you turn the switch to "on" that can sometimes fail. It’s dead. The only air that I get now is when I drive my car and the fresh air button is pressed on and it’s cold then but if your not driving it is really hot in the car if you’re not driving. Canadian 450 VIN Database US G&K 450 VIN Database Members Calendar Site Activity All Activity Search More .

A proper diagnosis is highly recommended if you are uncertain of the issue. The mechanic … The 1999 Chevrolet Cavalier has 8 problems reported for fan does not work on all settings. Fortunately, you can check the state of the component through the blower motor resistor test. This will cause the blower motor to operate incorrectly or not at all in one or more settings. The first thing I would check is the blower motor resistor. Once the resistor is disconnected, it is often possible to determine whether the resistor has blown or not based on its condition. Have 1999 Plymouth Voyager- My heating/AC front blower motor stopped working on all but high speed (everything all at once) and also the A/C and recirculate goes out when try to switch to any other speed except high. A failed blower motor resistor will usually cause symptoms that can be easily identified. This device will usually be located near the blower motor under the dash, and will have an electrical connector with 4 to 5 wires coming out of it. Initially it was suspected that it was just a faulty pack so they fitted another free of charge. If you desire testing, and replacement, as needed, please request a blower motor/resistor block diagnostic and the responding certified mechanic will get this taken care of for you. Well your blower motor is fed via a Fuse (fuse 23 (which is 40amp) then two relays (relay 1 and relay 2). 2. If I shut the car off it will not come on for 3-5 minutes. It is very likely that the blower motor switch will no longer work. This electrical component is used to control the air conditioning system of a vehicle. Another common symptom of a faulty blower motor resistor is a a blower motor that does not function on certain settings. Most blower motors ground through the case of the motor when it is screwed into place or by a small ground strap from the case to the body of the car. If the resistor fails, generally, the blower will only work on select speed settings. If fuse is good make sure you have 12 volts to fuse 25 when the car is running. A proper diagnosis is highly recommended if you are uncertain of the issue. This article applies to the Chevrolet Silverado GMT800 (1999-2006). Vehicles affected include the Corsa D (2006 onwards).

Owners may experience an intermittent heater blower fan, on one or more of the speed settings, or the fan may not work all, or will only work on full power, or may be stuck on full power. Much appreciated. There are also some instances where the blower motor may not work at all. (The resistive power drop is a really cheap way for Ford to control the current, and hence the speed of the fan).The reason the fan works on setting 4 and not on the other 3 settings is that the full speed setting 4 bypasses the resistors and the thermal fuse. Again a few weeks later this second replacement failed. If you notice smoke or a burnt smell from your air vents, this could possibly be due to the blower motor resistor overheating, which may have burned some wires inside the dashboard.

My car's heater (and AC) have 4 different blower settings. This occurs because the faulty blower motor resistor is not able to control the current flow. As part of our comfort and luxury, the blower speed is one of the most adjusted settings in a car, and so the resistance of the blower motor is constantly being put under stress, which can eventually lead to motor failure; too much humidity in the atmosphere can lead to an increase in resistance. Check the fuse with a multimeter. Got in the car this morning and the blower isnt working at all. Well, I don’t think it’s the fuse (otherwise the fan wouldn’t come on at all,) it’s probably not the blower motor resistor either.

What about the coolant level? There are also some instances where the blower motor may not work at all. Some cars have blowers that have 4 to 5 fixed speed settings that can be selected, but in this case, the speed of the blower motor is controlled by a blower motor resistor. My car's heater (and AC) have 4 different blower settings. Check for power at the motor itself. When the resistor is working, it reduces the amount of voltage going to the lower fan speeds, so the fan runs slower. The fan blower for your ac/heater is located under the glovebox. The resistor is responsible for making the blower motor run at slower speeds than high or (4). Another symptom of a faulty blower motor resistor is that the blower motor cannot operate in some settings. To determine the cause of a blower fan failure, isolate the motor, and perform some basic electrical tests. The estimate does not include taxes and fees. Autoblog is part of Verizon Media.
