Question about 2000 Buick LeSabre
It's so easy to solve this!
My stepfather gave me his 2000 Buick LeSabre and told me that the light switch was stuck. For weeks, I was driving around, frustrated because the battery would die if a valet attendant or parking lot attendant would inadvertently push the button in.
I thought it would be prohibitively expensive to fix the light switch. I was wrong.
I went online and searched for a new part, finding the switch for around $80. Once it arrived in mail, I was going to bring it to the shop to have a mechanic put it in. I then realized that when you open the driver side door, you can simply pull the decorative panel to the left of the steering column, from the left edge towards you, and it simply pops open. No screws, just pull.
Once you've done that, simply unscrew the part from the panel. Then pull the plug from the part and voila, you can simply replace it with the new one. Screw it back onto the panel, push the panel in and you're on your way.
$85 plus shipping later and you've solved one of life's great mysteries!

This is a very easy fix. No need to go to the dealer. I found the switch at Autozone for $70. Just like djtonyz said, slide the trim panel to the left, pop it off and remove one screw and replace the switch. Less than 15 minutes to change. Thanks for the great help.

The switch is poorly designed. I disassembled the switch assembly and removed the pushbuttons that actually activate the switches. You can then press the switches directly with your finger. However, you lose the symbols that identify the switches and you will see the greenish lights that backlight the pushbutton symbols. I made some stick-on labels for the dashboard and didn't have to get a new switch assembly. Since the headlights are activated automatically by the dashboard sensor, I rarely use the switch anyway.

First I found a backup plan... I found a replacement switch available at my local AZ store for about $85. Not bad compared to dealership and easily replaced if you remove the dash piece with care.
Now knowing I had a way out I disassembled the existing switch module and discovered the exterior switch face is attached to a hard plastic tube that slides over a hard plastic shaft inside the switch. I cut approx. 1/2" off of the outer tube which seemed to bind no matter how much I cleaned and lubricated it. Because of the way the switch face is held in the assembly it remains in position even with most of the shaft removed. Then I carefully reassembled the switch. I had broken one of the tabs during dis-assembly so I put a drop of glue on that. Reinstalled the switch and it has been working fine for 6 months now.

After reading these posts I went out and fixed my 02 lesabre. I VERY carefully dissasembled the switch. The problem is the clearence for the buttons. I removed the buttons and filed the Female part with a rat tail file. then smoothed the the rest with a fine wire brush. put it all back together. PROBLEM SOLVED. DIDN'T SPEND A NICKLE!

In warm weather (where the inside of the car gets hot), the switch will easily move in and out. If in cold weather, use a hairdryer to heat it up.

I had the same problem.
I figured out the solution to the problem.
If you look at the disassembled switch very carefully, you will notice wear marks on the sides of one or both switches.
You will also find, that when trying to slide the outer switch over the inner switch, that either one or both may stick. (even when unassembled. )
I first used a razor knife to trim off excess material on the inner switch to prevent sticking. Apparently - with age and heat, the inner switch post becomes slightly deformed - not round - and causes the outer switch to stick.
I then used compressed air to completly clean everything up.
Then, I sprayed a light coating of silicon over everything.
I also checked the fit of the switch into the outer bezel. I had to slightly enlarge the bezal to prevent sticking as well.
Again, I used compressed air, to blow away any silicon residue.
I reinstalled the switch and it works like new.
I expect that with the enlarged clearances, the switch will remain operational for a very long time.
