Where is the blower motor located on a 1986 buick century?
Under (and inside) dash on passenger side.
From what I have read online, it should be near the actual blower motor under the dash. They say it is easy to replace, but hard to get to. I plan on replacing mine as soon as I get paid. It is behind the blower motor... http://wiki.answers.com/Q/How_do_you_replace_the_resistor_on_the_blower_motor_of_a_2002_Buick_Century_The_fan_works_are_on_higher_speeds_only_Does_not_work_on_low_speeds
I think you must be referring to a blower motor relay located most likely on the firewall toward the passenger side. But, i don't know exactly which relay is the blower motor relay, as there are several relays closely located together. your resister is located below your relays on firewall.follow the wiring from blower to firewall.left side of blower motor.2 screws hold the resister down,and 2 wire harness.hope this helps
