What problems can be caused by Overlubricating a blower motor?
Loss of lubricant through leaks or other means can result in overheating and failure of the bearings and gears. Over-filling the oil sumps can also result in failure due to excessive foaming. The failure pattern of the gears is very similar to that of no oil.
Can wheel bearings be over greased?
Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.
How do you lubricate a needle bearing?
Needle bearings are usually lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications. Many light-duty bearings never require relubrication, but high loads or speeds demand it.
What to do if your power window is not working?
Each car door with a power window has a window regulator to move it. If the regulator goes bad, then pushing the up or down button will not make the window move. You will need to have the window regulator replaced. Every power window requires a window motor to supply the electrical energy.
How does a power window work in a car?
Every power window requires a window motor to supply the electrical energy. There is a gear at the end of the power window motor which connects with the window regulator. When you press the up or down button on your door, it activates the window motor which then allows the window regulator to move the window.
Do you need a crank handle to open a power window?
It is very convenient to operate a power window because you just need to push a button on your door to open and close it. You don’t need to go through the hassle of rotating a crank handle with your hand.
Is there a problem with the GM blower motor?
If you have a General Motors car or truck from 2002 through 2008 you’ll probably have a blower motor issue at some point. In many cases it’s a problem with the GM blower motor module. The most common complaint when this part fails is the motor will not turn on at all.
How can I tell if my blower motor is working?
If the blower motor works it’s time to check some voltages at the module. There’s a power wire that comes from the control panel. On most models it’s either red or purple. This power in wire should turn on a test light with the ignition on and maximum speed selected. The black wire should indicate a strong ground.
When do you need to replace a blower motor?
If you don’t feel any airflow coming out of the vents, it may mean that a problem with the blower motor has developed to the point where the component is entirely inoperable. In this case, you’ll have to replace it with a new motor.
What does Black Wire mean on GM blower?
The black wire should indicate a strong ground. If you have a good ground and verified power into the module, yet have no electricity flowing to the fan you probably have a bad module.In many cases when I find the problem with the GM blower control module I also find signs of moisture in the heater case that contains the motor and module.
