The bumps are usually accompanied by redness and swelling. Allergic eczema is an allergic skin reaction that produces an itchy, red skin rash. The rash may consist of raised, red bumps that ooze, drain, or crust. Angiomas are common skin growths that can form on most areas of the body.
Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically, using a rotating lever, or electronically by the air conditioning system.
What is the Heater Blower Motor all about? The heater blower motor forces air through the vents. You are able to control the speed of the motor through switches, buttons, and dials on the dashboard. The motor contains a resistor which allows it to change the speed of the fan. Without this part you will not be able to change the speed of the airflow from the blower motor.
