Do you have a hi speed blower motor?
I have no hi speed blower motor. I have replaced the fan switch, the blower relay,and still have ni High speed, on a/c or vent or anything. Anyone else had this problem?
What causes a blower motor to stop working?
In a situation where the motor doesn’t work on any speed, the most likely causes are: a blown power supply fuse, a bad motor ground connection, bad motor speed control module or a failed motor. On all systems, a failed blower motor is least likely. Blower motors generally don’t fail out of the clear blue.
Why is the resistor not working on my blower?
Hi There, The resistor is what controls the speed of the blower motor, not the relay. The blower motor relay supplies power to this motor when you turn the switch to “on” that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all.
Why does my heater not work on high speed?
Heater blower motor will not work on high speed? I have replaced the black bosch relay behind the glovebox, the blower resistor and the blower motor and still cannot get the blower to work on high. I remember in older model years of gmc’s and chevys that their was a high speed blower relay that caused this issue.
Why does blower only work on high only?
A bad blower motor resistor can cause your blower works on high speed only. Older style blower motor resistor with exposed resistor elements. The blower motor resistor is what’s responsible for giving you three blower speeds. The resistor block contains three different high resistance coils.
Why does the blower fan only work on high speed?
The fan only working on high is normally due to a defective resistor pack. The resistor pack is used for all speeds except for the fan’s highest speed where the resistor pack is bypassed.
Is my blower motor bad?
No air from the vents. No air flow from the vents when the heater or air conditioning is activated is another symptom of a bad blower motor. If the heater blower motor burns out or short circuits, it will not function, and therefore will not be able to produce any airflow for the system. The blower motor will usually have to be replaced in order…
Is there a way to test a blower motor?
Blower Motor Resistor Testing Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. Move the lead from terminal 2 to terminal 3 and check this reading against specifications. Move the lead from terminal 3 to terminal 4 and check this reading against specifications.
Why is my high speed fan not working?
Sometimes my high fan speed starts working if I pound my fist on the dash, but it usually stops the next time I go over a bump. Oh, well. Samething here eyeofthetiger. It comes on at odd times and not when you wan it to come on, im thinking its a bad ground or short in the wire. Myabe a factory issue? You know I had a similar issue.
What does it mean if your blower motor is not working?
Average rating from 849 customers who received a AC is not working Inspection. The blower motor resistor is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed.
