Introduction to wiper rubber replacement.<\/p>\n
Wiper principle: the wiper on the motor.<\/p>\n
It is driven by a worm wheel on an armature and the output shaft operates the output arm that connects the wiper bar.<\/p>\n
When the motor turns, the output arm and the connecting rod are driven forward and backwards.<\/p>\n
A resistor on the control switch is connected to the armature winding of the motor to control the speed of the motor<\/p>\n
The driver can toggle the switch as required to allow current to flow into the motor’s input circuit.<\/p>\n
Above you have described when to replace the wiper rubber.<\/p>\n
You must be aware of the time and interval for replacing the wiper blades and Ensure safety.<\/p>\n
