Heater blower went out


Normally when the blower motor goes out it has trouble a few days before and cuts in and out so I would check fuses first but I may be wrong and if the fuses are fine the I would change the motor

Location for blower motor/heater/fan fuse?


Before you rip, check the 30A HEATER CIRCUIT BREAKER in the instrument panel fuse panel. The input is hot with the engine running. CB output connects directly to the heater blower motor. A cluster of heater blower motor resistors determines blower speed as selected by the blower switch in the heater control assembly. The switch setting is sent to the powertrain control module (PCM) which acts to turn the blower motor on at the selected speed.

2000 buick regal blows high fan fuse as soon as it is put in with car offf


I would disconnect your blower motor resistor then try fuse again, if it does'nt blow then it is either blower motor or resistor,these resistors are common for going bad/and or blower motor. Good luck let me know if you need more info or if this didn't fix it, I will research it more for you

Heater fan not working


The three most common problems for heater fans are
  1. Burned-out blower motor resistor. This is usually located on the engine side of the firewall. Sometimes one section of the resistor is burned out but others are still good, so the blower only works on the highest speed settings. If you have a burned-out resistor, check the blower bearings to make sure they are not stiff and causing the motor to draw too much current.
  2. The blower is actually working, but either the intake vent is plugged (I've seen vehicles with the heater core completely blocked by dirt, leaves and insects that came in through the vent), or the heater door is stuck closed.
  3. The motor bearings have gone bad (see # 1). This can cause the fuse to blow, although the resistor usually fries first.
I'm not sure how your car's cabin environmental control system is fused. Check any fuse that might apply, such as Vent/AC, HTR, FAN, etc. Generally you can identify the state of a blade-type fuse by inspection without removing it. If you have a blown fuse, check the blower motor before wasting money on a new fuse that will probably blow. Like any fan, it's supposed to turn easily, and there should not be any roughness or side-slop in the bearings.

Heater fan works for a while then cuts off till it cools down




What can go wrong with a blower motor?
There are several things that may cause your blower motor to stop working. The simplest cause would be a blown fuse. If you replace the fuse and it quickly blows again, then you probably have an electrical short. Disconnected wires on the exterior of the blower motor can also cause it stop working, and if your blower motor gets dirty, it can get clogged or muddy which keeps the fan blades from spinning.

How do I test my blower motor?
When you are troubleshooting your blower motor, it is best to start by running the air conditioning or the heater to see if you can hear the sound of the fan. If you can hear the fan, it could be clogged or corroded with dirt. If you do not hear the fan, then you may have a bad resistor, blown fuse, or a loose wire. Next, you should replace any blown fuses in your car's fuse panel and try to start the blower motor again. If another fuse blows right away, you have an electrical short. If it doesn't blow out and the motor is still silent, then something else is wrong. In the case where the fuse lasts for a little while as the fan spins but then the fuse blows again, that usually means you need to replace the brushes on the motor. Finally, you can pull the motor out and visually inspect it for loose wires. If you don't see any and still want to test, try hooking it up to the battery to see if the motor will start. If all these tests still find you with a dead blower motor, it's definitely time to replace it.

How do I replace it?
Usually located under your vehicle's instrument panel, the blower motor can be removed and replaced. You'll need to disconnect the blower motor connector and remove the retaining screws holding it into place. Detach the fan retainer clip from the motor shaft that's located in the center of the blower wheel. You may need to save that piece if you are not replacing the whole motor. Inspect your new motor to ensure nothing is broken and the blades can properly spin. Re-attach the fan retainer clip, the retaining screws, and the connector so you can test your new blower motor out.

Fan is not working even i use air condition or heater no air coming out and i don't know which one to replace?


First check the fuse for the heater/ac fan. If the fuse is OK, you probably need a new blower motor. If the fuse is blown, replace it. If it blows again, you could have short in the heat/ac control computer, or the blower motor may still be bad. In this vehicle, the blower motor is probably less expensive to replace than the controller, and you can test the blower once it is disconnected by applying battery voltage to it (observe correct polarity). If it does not move when jumped directly to the battery, it is almost certainly bad.

Air stopped blowing on ac/heater


Check your fuses.If you have a test light, unplug the blower motor, start the car, turn the fan on, if you have power to the blower plug, the blower motor is bad. If no power, if it's not a fuse, check the blower motor resistor. Should be mounted right next to the blower motor. It is inserted into the evaporator box
