Blower Motor Resistors
System stress shortens blower motor resistor life. Common failures of blower motor resistors are due to thin trace widths on the printed circuit board – usually caused by stress on the system due to increased current flow. The thin trade widths are not capable of carrying a large amount of current for long periods of time, so the traces burn out, causing a loss of one or more blower speeds.
Airtex engineers designed its blower motor resistors to have thicker trace widths for longer product life.* *Airtex Innovation applies to 3A1319, 3A1297, 3A1271, 3A1179, 3A1154, 3A1151, 3A1312, 4P1492, 4P1650, 3A1029, 4P1338, 3A1026 and 3A1282
Repair tips • Visually inspect the entire blower motor electrical circuit – including the blower motor, blower motor resistor, switch, connectors and wiring – before replacing any component in the blower motor system. • Clogged cabin filters and air vents shorten blower motor and blower motor resistor life. When replacing the blower motor or blower motor resistor, clear vents and check or replace cabin filters.
• Ceramic-coated, steel-printed circuit board design for durability and longevity • Thermal fuse equipped • Thicker trace widths than OE • Mounting and connector identical to OE
• Larger traces prevent premature burnout • Longer blower motor resistor life • Ceramic-printed circuit board for heat dissipation • Direct OE replacement • Thermal fuse prevents overheating of blower motor and damage to other vehicle components
