2006 Buick LaCrosse ** Both Front Power Seats have PARTLY Stopped working. **

[Christoff]

Looking for Information - I will post post what I know & keep my fingers crossed that SomeOne can provide the Information I need.

I have a -
2006 Buick LaCrosse 4 Door Sedan with 170k miles.
** Both Front Power Seats have PARTLY Stopped working. **
BROKEN - UP/DOWN Positioning, witch is more at the Back of Both Front Seats.

Still Working...
✓ Power Forward & Back,
✓ Power Tilt at Front of Seats,
✓ Driver's Power Lumbar Support,
✓ Seat Back Adjustment is Manual & Works.

Hoping for a very specific "What / Where to Look" so I can Repair this specific Issue.

I am assuming it is an Electrical Issue at this point.
Where (Which) Fuse Panel & which # Fuse, am I looking for ?
Is there a Relay of some type in addition to a Fuse ?
Is there a Wiring Harness Connection Point that would affect UP & DOWN on Both Seats ?

Thanks in advance, ~Christoff
Ps,
I am a Mom & Grandmother that knows how to turn a wrench & change my own oil (when/if I have to).
I have no need to reinvent the wheel, when someone out there has the exact Information I need to Fit an Issue - So I ask Questions ! 👩🏼‍🦳

On the seats the module and harnesses connector is if you have other functions especially when both have the same issue. Other than checking the harness is in good condition, the connections are clean and secure not sure other than using a meter what else can be a DIY project.

Here's some photos and diagrams that may help.

@2007LucerneCXL Thank You !
You would not happen to know the Specific Fuse Box Location (the Car has at least 2) & a Fuse # ?

The last time I went Looking for Electrical Information on this Buick, it took forever & I found the Information was less then clear.
I was able to determine (eventually) that the Fuses & Electrical was good, but that the Cabin Fan was shot (dead), did not want to Disassemble the Dash myself so Hired a Mechanic to Replace the Part.
