Blower resistor is defective. Price depends on type of climate or temperature control, automatic or manual.?
Auto: NAPA Part BR539 = $77.00.......Manual: NAPA Part BR266 = $18.49. Buy the resistor and install it yorself.!
Be sure to check the wire connector for signs of melting plastic and replace if needed, also avail @ NAPA. See youtube for install video, easy diy repair! If not equipped, have it installed!
