There could be several reasons why the blower only works some of the time. It could be a faulty blower motor, a problem with the blower motor resistor, a malfunctioning switch or control module, or an issue with the electrical connections or wiring. It's best to have a professional diagnose and fix the problem to ensure the blower works consistently.
What else can I help you with?
Why does the heat blower only work on low and medium but not on high?
It could be due to a faulty resistor in the blower motor circuit. The resistor regulates the speed of the blower motor, and if it malfunctions, the high speed setting may not work properly. It would be best to have a mechanic inspect and replace the resistor if necessary.
Why does the blower fan only work on high speed?
The blower motor resistor module is ruined and need replacement. It can be found from below and behind the glove box. Tt may be hard to see, follow the wires to connection that is mounted to the blower unit by two small hex-head screws. I removed the glove box so I could access it easier than trying to go from the bottom in a confined position.
What formula relates work and power?
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
Is work done every time forces are exerted on an object?
No, work is only done if the force causes the object to move in the direction of the force. If the force is exerted but the object does not move, no work is done. Work is calculated as force multiplied by the distance the object moves in the direction of the force.
How do you calculate work with power and time?
Work can be calculated by multiplying power by time. The formula is: Work = power × time. This equation is derived from the definition of power, which is the rate at which work is done over time.
What is the problem when the blower fans only work some of the time on a 1999 Alero?
Just had the same problem. First my blower motor would onlywork on "high", and then it started to change speeds and shut off by itself. Replace the resistor mounted in front of the blower motor.It costs about 40.00 at a dealer.
Why does only the HIGH blower work on my 1997 Nissan maxima?
Your blower switch sensor is out. Replace it!Then all the speeds will work
94 jeep Cherokee heater motor only worked on high and now does not work at all?
Probably the blower motor resistor, check blower motor at the same time
Why does the acheater blower only work on high speed?
either the blower control switch or the blower motoer needs replacing
Why does the heater blower only work on 3 or 4?
You most likely will have a bad blower resister........
Why your 1999fordrangerheateronlyonhigh?
truck blower only work on high
Why does the blower only work on high and no daytime running lights?
A blower motor that only works on high is normally caused by a defective Blower Motor Resistor Pack. DRL, do not have a clue.
Why does the heater blower only work on high?
from what i have read it is the blower motor resistor it goes bad and only lets the fan run on high google blower motor resistor and read on
Why does the blower fan only work on high in a 2006 Chrysler Sebring?
blower motor resistor needs to be replaced
Why does the blower motor only work on high even when the ignition is off?
it's a problem with the blower motor resistor,
Why do your ac blower only work on high on your 1996 Chevy impala SS?
faulty blower motor resistor
Why would the fan blower not work in a 1994 Silverado?
AnswerIf none of the speeds work check fuses and the power at the blower motor. Since blower motors work most of the time, the blower motors do burn out. If it works on high speed only, then the blower resistor behind the glove box is possibly bad. MarkCheck the ground to the motor. Best thing to do is ground the motor and see if it works. I have seen this problem before and putting a different ground on it fixed it.
