Blower motor works on speed 4 but not on speed 1 or 2 or speed 3?

Need to replace the blower motor resistor which is located just under the passenger side dash. 2 bolts on either side will remove it. Cost of replacement resistor is about $20.

What causes the heater blower motor in a 2003 Trailblazer to not work in speeds 1-3 but works in speeds 4 and 5?
Probably the blower motor speed resistor is partially burned out.
2002 gran prix blower fan works on high only?
Low speed (1-4) relay bad Switch bad Low speed motor winding bad
99 sunfire heater only works on full speed?
1) Check the blower motor, make sure it is not making any weird noises.2) Check the blower motor resistor, its located next to the motor. It is what controls the lower speeds of the motor. You can try to find one at the junkyard.
Why does blower on 2003 Chevrolet Trailblazer work on 5 but not 1-4?
The blower motor speed resistor is burned out.
The blower in my jeep wrangler stopped working while it was on could this be a fuse problem?
It could be a blown fuse but more likely it is either the blower motor resistor or the blower switch itself. TJ's are prone to overheating and melting blower motor switches because of high current flowing through them. To test the switch, check all four fan speeds to determine which of them is inoperable. The blower motor resistor regulates the blower speed on positions 1 through 3. If the blower doesn't work on any position 1 through 3 but it works on full speed (Position 4), the blower motor resistor is bad and needs to be replaced. If the blower doesn't operate at full speed (position 4) the blower motor swithch is bad and you need to replace switch assembly, After that, check the lower fan speeds to make sure they work. If any of them doesn't work, replace the blower motor resistor also.
Why doesn't fan blower speed 1 2 3 work and speeds 4 and 5 do?
the blower motor resistor is broken, get a replacement.
2001 ford focus blower works on 1 and 2 not 3 and 4 replaced resistor no help?
Next guess is motor. Blower motor that is. maybe a switch? Probably the motor itself, if it isn't the switch.
How do you repair an air conditioner on a 2004 Chrysler Sebring that only works on level 4 and nothing happens on levels 1 2 and 3 you already tried replacing the switch?
If you are talking about the blower motor speed settings, and it only works on the high 4 setting, then the Blower Motor Resistor Pack is bad. Replace it. It is located under the dash on the passenger side.
Where is the front Blower Motor and blower motor resistor board located on a 2000 Mercury Villager?
Open the glove box door and remove the glove box. You should now be able to look directly at the motor and the resistor. >In 1999, they changed from the coil type resister to a printed circuit board. The coil type is about 2 1/5" long by 1 1/2" wide with kid of a square 4 wire connector. > The 2000 printed circuit type is about 4" long by 1/2" wide with a 4 wire connector with all the wires in one row. It's right up against the fire wall and partially hidden by the carpet. It's there, you just have to look. The tube you see is a cooler tube for the blower motor. It takes air out of the plenum case and directs it though the tube and into the motor housing. > > By the way, if the resister has the internal fuse burned, you probably have a blower motor starting to fail and it's drawing too much current at times. It will get worse. > You need a blower motor from a 99-02 Villager/Quest. >In doing some research on my own problem, which is the same as yours, I came across an answer for both of us. From March 2006 there was an answer that said that the control module was bad. He said that this used to be called a resistor pack. It's located behind the glove box. He said you open the glove box compartment and make it swing all the way down by squeezing in on the sides. You'll see the module attached to plenum with two plugs connected. Unscrew the two screws to get the module out. New part number from dealer is 5179985AA. The original part number has been discontinued. He said (in 2006) that the dealer cost for the module was $56.00 and you can replace it yourself in about 10 minutes. Blower Motor Control - Manual Control System The position of the blower motor control knob determines the speed at which the blower motor (18527) operates. Each position of the blower motor control knob is detented for positive engagement. The blower motor control works in conjunction with the blower motor resistor to control the four-speed operation of the blower motor. The blower motor control switch can be replaced separately from the manual control assembly. Blower Motor Control - Electronic Control System The rotation of the blower motor control determines the speed of the blower motor. The blower motor control works in conjunction with the A/C blower motor speed control (19E624) to control the 12-speed operation of the blower motor. Blower Motor The blower motor (18527) is mounted within the A/C evaporator/blower motor assembly, and contains the following: blower motor and blower motor wheel (18504) blower motor resistor (with manual control option) A/C blower motor speed control (19E624) (with electronic control option) A/C air inlet door (19A813) A/C air inlet door actuator motor A/C evaporator core (19860) (if equipped) Blower Motor Resistor If you have EATC, Electronic Automatic Temperature Control for your heater/a/c system, you WON'T have a blower motor resister. Instead, you will have a blower motor speed controller in that location. If you have an electronic digital temp control system with a digital display. If so, you have a blower motor speed controller instead of a resister. The controller is a 3" x 3" box with fins on it for cooling. It is located under the dash by the blower motor, just to the left. It has a white aspirator hose routed over it. 2 screws and one connector. It is fairly expensive so be sure it is the bad part. I have one I salvaged a while ago for a spare just in case someone needed it. The aspirator hose takes air from the resister location and feeds it to the temp sensor that controls blower speed, etc. So, your problem could be the motor, the speed controller, the digital control head, the sensor, wiring etc.
The low speed and second speed blowers doesn't work for the blower motor?
the reason blower does not work on all speeds, is the fan blower motor resistor. The resistor is a 4-5 step series circuit, 1 resistor is added for each reduction in speed. If one burns out then so will all speeds below it. The "high" circuit usually has a separate fuse and bypasses the resistor altogether.
Why wont a 1995 Chevy Tahoe blower motor work?
First check your fuse 25 amp #12 on the drivers side fuse compartment then if it only works on high speed you have a bad resistor board (speed control ) this regulates the speed but is bypassed on HIGH.... next pry back the plastic cover and give the motor a rap with a screwdriver or hammer with the key on and blower switch on of course. if it starts you have a bad blower motor.. there are two types 1 wire and 2 wire so get the right one and good luck getting that plastic cover off...
