SOURCE: location of blower resistor

The 96 LeSabre Custom and LeSabre Limited use an electronic module in place of a blower resistor.
It is under the hood on the firewall on top of the heater plenum, but below the relay rack.
They tend to short and run on high until the module burns out and then it quits.
The same part is used on many high-end GM cars from 92 to 96. The electronic module has two connectors on it. (If yours has only one plug it is a real resistor pack and not electronic.)

The resistor is located on the blower housing on the firewall under the hood under the relay center boxes.

There are actually two possibilities for your issue. First is the blower motor resistor as you stated as a possibility. The blower motor resistor is usually located inside the blower motor housing unless the blower motor is mounted horizontally and is accessible from the engine bay (which I do not believe is the case in your Buick) in which case the blower motor resistor is going to be located in close proximity to the motor.

The other possibility is that the ignition switch is going bad. Now, this may seem strange at first, but GM ran much of the power for the accessories through the ignition switch and as a result, carbon builds up on the contacts and starts to affect the operation of the accessories. However, I dont think this is the case in your issue as that is normally accompanied by issues with other accessories like the radio and such.

I think it is more likely that the blower motor resistor is bad in your case. I believe your blower motor is located on the passenger side, against the firewall close to the center console. If you contort yourself in a way where you can look at the bottom of the blower motor housing you may see a connector on the bottom, or a small access panel. If so, that is likely the blower motor resistor.

I believe it's behind the glove box. Once you remove the glove box it's easy to get to. Hope this helps.

94 Buick lesabre, new blower motor and new control module. Blower stays on even with key out of ignition. What could be the issue? Relay or control module?


The only way for the blower to still get power with the key off...means the resistor to the blower motor is bad...The resistor is located on the firewall...under the plastic shroud...this should fix your problem...nice Buick...:)

You need to replace the blower control module. Its near the blower motor, on the firewall. Follow the wires from the blower motor, it should lead you to it.

Blower motor will not shut off. 2005 Buick LaCrosse


There is a bulletin for this fix.The bulletin number is 05-01-39-001A.This pertains to the blower motor staying on after key is shut off.What you will have to do is replace the blower motor resistor module and install a capacitor in the wiring.Part number is 25073556 for the capacitor.The blower motor is on the right side under the dash.Just remove the insulator panel and you should be able to see it if you look up into the dash.Or turn it on and listen for the blower motor.Disconnect the connector to the blower motor control module.Find cavity a and c.Cavity a is negative and cavity c is positive.C is red and A is black.Splice the positive lead of the capacitor to the red wire and the negative to the black wire.You should use splice sleeves and solder the wire on.Hope this helps.Good luck.

2004 Lesabre Blower Control Module Replacement - help moving DIM


First their is a blower motor resistor near the blower motor it controls and regulates the power going to the blower motor. This needs to be changed with the blower motor. If it was me and you want to fix your self with out taking to a shop I would change the blower motor and resistor. If this doest fix the problem you can return the items to your part store.One thing you can do is locate the resistor you will see the wires large ground and large power wires along with reg wires check to make sure it has power going to it on I believe 2 wires large power and small power wires if it does have power check other wires as you turn the fan high to low and see if anything. if you have power going to the resistor change them both. If this doesnt work and you still want to fix the modual should have 4 torx or 4 small metric bolts like 5.5 or 7mm remove them lift mod off. Just replacing most people do not recalibrate. At like GM they can put it on a scanner and check the operation of each part and they also reclibrate with the "Tech 2 scanner" . but first check the resistor for power if it has power change the resistor and blower motor
