2004 Lesabre Blower Control Module Replacement - help moving DIM

The blower motor on my 2004 Buick Lesabre Limited stopped functioning yesterday, with no particular warning or notice. It simply no longer blows air, regardless of setting. My car has the electronic integrated a/c control system, and the display indicates that it believes it is telling the fan to blow at appropriate speeds based on the temperature I set

I replaced the fuse for the blower, although it did not appear to have been blown. When I restarted the car, after a few seconds, the blower worked, and worked after perhaps two or three restarts, then stopped again. I didn't then (and still don't) believe the fuse it the issue.

I believe the problem is either the blower itself or the Blower Control Module, and the research I've done has led me to some manual pages that go through the steps of the replacement. The last step, however, has me wondering - "Recalibrate Actuators." The system is entirely electronic, with no manual switches, so I'm not entirely sure if I can accomplish this step.

At this point in the repair, I have already removed the blower, and the cage appears to be spinning freely with no resistance or what I would interpret as such. It has three prongs, so I'm not sure which two I would use to apply voltage to test the blower motor itself. I am almost at the point of removing the blower control module, but am stuck at a removing the Dash Integration Module off of its mounting bracket. I can't tell how the DIM is affixed to the bracket, and I'm very concerned about accidentally damaging it. At this point, I blame either the blower motor or the control module.

So, in a nutshell, I have three questions: 1. How do I remove the DIM from its host bracket, and 2. Is my interpretation of the info on the blower correct in that it expects 14V across two of its three pins? If so, which two? 3. How do I "recalibrate" the actuators on an *electronically* controlled system?

Many thanks in advance.

    seans46, the problem with replacing the resistor pack that it appears to price out at something on the order ot $200-$250 depending upon source, and as an electrical component most part shops don't take back (or impose a heavy restock fee) on electrical parts. I'd like to avoid that expense if at all possible.

  • soonerdew May 25, 2009

    Thanks, seans46. BTW, I have also read that replacing the resistor pack with the blower is recommended for blower motors on *pre-2000* Lesabres; do you think that still applies to a 2004 model?



    Also, any thoughts on removing that DIM off that bracket? I'm almost to the point where I think I could reach the only screw that holds the module to the blower housing without moving that bracket...but there's gotta be a trick to how that module is mounted to the bracket...

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

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...:)

The a/c blower motor is not working


the blower motor or the blower speed control module is bad. turn the a/c on and rap on the blower motor a few times, if it doesnt work check for power at the blower motor, if it has power the motor most likely bad, if NO POWER then the module is bad.

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