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.
The speed of the pulley, driven by a fan belt, is the speed of the fan; when the engine runs faster, the fan runs faster. When set up correctly, it pulls enough air across the radiator to keep the engine cool (and the air conditioner working, if the carâs equipped).
