I finally replaced the Backlights, using a guide from a person at www.answerbag.com

(i've got an 04 limited. i just soldered in new bulbs for the lighting controls panel (5 #272-1092) and the digital HVAC panel (1 #272-1092 and 5 #272-1154). steering wheel control bulbs are next. )
Just buying a cheap Used one may be the best, if you are not good with dis-assembly and soldering small electric bulbs
Depending on the style you can get a Used One from an online junkyard for 25-50 USD

The most difficult part is getting the Climate Control Module out of the dash, to make the soldering new bulbs repair.
The wood-grain Bezel needs to come off, BE CAREFULL, its long and flexible and can crack easy if the wrong pressure is applied or its cold outside or cold in the car cab. Its held in the dash with GM friction clips ( pain in the %$#) and 2 Phillpis screws behing Glove Box door. I worked the pull- pressure from the A/C vent on Right, left-ward to the center, and from Steering Column right-ward toward the center.
Once the Bezel is removed, the Climate Control Module is seen, with 4 push-tabs on each corner. BE CAREFULL pushing in the tabs....I broke off one as in pushed too hard. Pry out Right side while pushing 2 right-side tabs gently together. Repeat for the Left Side, while pushing 2 left-side tabs together gently. The Climate Control Module should pop out.
Use a 3/8inch Nut Driver to remove the headless screws that hold the Climate Control Module PushButton plate to the box. This will expose the Printed Circuit Board for solder replacement of the Bulbs.
SOURCE: 2003 buick lesabre heated seats wont work
I had this problem, but only on the driver's side (with leather seats). Sometimes the switch would come on, but I could not get it to go back off (and the seat would not heat).
I ended up removing the drivers front seat cover (only the bottom part), folding it back from the driver's door to the middle of the car. You also have to unplug the wiring harness underneath the seat. I found a black spot burned in the foam. This is where a wire had broken. I carefully pulled the wire together, then soldered it. I put everything back together, and it has been working ever since (about 6 months - and getting lots of use in the middle of the winter).
I think the only way to replace the heated seat wires is to replace the whole seat cover. I was glad I could fix mine by soldering it.
