The resister module is behind the blower motor right against the firewall. It is held in place by three 7/32 inch screws. The back two screws are very difficult to remove because of the insulation on the firewall. I have found it a little easier to slit the insulation on both sides of and just under the module and pull it down out of the way. Also it makes installation a little easier if you don't completely remove the two back screws. Take them out about half way, enough to pull the module down about 1/3 inch and slide the module forward and then down.
where is the switch resistor on 2003 buick
i have a 1998 buick century and my blower motor is under the passenger side front wall inside.I found out that the blower motor resister was the problem.if it works on high speed only,replace the resistor first.it's cheaper but harder to get at.
Defective Blower Motor Resistor Pack.
The blower motor resister is located just below the blower motor to the left attached to the housing.........
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...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
where is the blower motor resistor located on 97 buick skylark
where is the blower motor located in a 98 Buick century custom?
blower resistor is behind fusesand realays under hood bolted into air duct
Either than switch, the resistor, or the relay is bad. On my 1999 Buick Century, the blower motor quit working on the three lower speeds, and then went out completely. When the resistor goes bad, the lower speeds quit working. My blower motor was squealing, also. After I replaced the blower motor and the resistor, I tested it and found the blower worked great on every speed but high. It turned out that there is a separate circuit for high speed, and the fuse was blown. I replaced the fuse for the high speed, and the blower now works on all 5 speeds. Replacing the blower and resistor was difficult, but not as bad as expected, thanks to help from this site.
You may have to vmove them to get at it
I believe that it is under the dash on the pasenger side up towards the fan motor
You probbably have controler problems but the resistor is on the evaporator case.
