Update: My son'* finally about ready to take care of the issue. I had the car running to cycle the steering back & forth a few times after adding fluid. Turned on the headlights, and the hi beams don't come on. In fact, the whole assembly seems to move, I believe it'* just supposed to click, and I don't think the rest of the plastic piece on the column is supposed to move. I tried Amazon, ebay, and Autozone, could only find the stalk, or the turn signal switch inside the column.

Also, there are a few early 2000'* LeSabres at Pull a part, I don't suppose they use the same part?

When you pull back on the turn signal lever, it is supposed to click, then you release and it should return to the position where it started. This would activate the high beams.

Then same lever behavior again should return it to low beams.

I believe the correct part number for this is GM part number 1995967.

I believe I found them for sale at Rockauto: https://www.rockauto.com/en/catalog/...al+switch,4832

If it were me, and if my 1998 Bonneville had Electronic control and push buttons, I'd probably buy Standard Motor Products TW26

No, they don't. It'* a whole different "modern" new design.

Ok, I got the TW 26, and looks like I'll be installing it over the weekend. Main concern is the air bag, I was looking at the service pages posted earlier, they talk about pulling the fuse. I thought pulling the negative off the battery was typical. I also watched the youtube clip on another thread, the guy'* replacing the ignition switch on a '79 T/A, just to remind myself of the process. I tried to see if the local shop would do it, they had a conversation about what'* involved. When they said the steering wheel has to come off, one said "nah, he wouldn't even touch it!" Other guy said what a PITA of a job it was, and HE wouldn't want to do it! There'* the other shop up in town, that replaced the timing chain on the LaCrosse, they'd probably do it, but I don't think I wanna know what they'd charge!!

It'* not a big deal, just be patient and pay attention to how all of it comes apart.

Not sure why any shop would turn that job away. It'* fairly quick work for okay money.

For the airbag, disconnect the battery. When I did it, I disconnected the battery while the headlights were turned on to make super sure that any excess power got sucked out of the system.

Then disconnect the big yellow plugs under the dash.

Then get into it.

Don't reconnect anything until the airbag is completely back in and you're finished messing with it. I made sure to stay completely clear of the airbags while I reconnected the yellow connectors, just to be super safe. Reconnect the battery last.

When I fixed my turn signal switch on my 1997 LeSabre a couple of years ago, I was in and out in about 90 minutes.

Well, it'* a Mr. Tire, so they pass on any really "involved" jobs. But, it'* the closest shop, and they've served us well over the years.

Well, bought a puller kit at Autozone, got the wheel off. Then, there'* an air bag module, with one of those infernal snap rings, w/the little holes. Picked up a pliers kit with interchangeable noses. Even with the smallest one, still hard to get a grip on the damn thing! But, finally got it, and then, there'* that steel ring, w/the locking pawls. I set aside a steel bracket I had, for potentially making a tool to press that ring, but lacking a shop vise or a drill press, went back to the 'zone, which was out of stock. Thankfully, there'* an O'reilly'* next door, they had the tool. Then, I couldn't get the snap ring off! Couldn't get a decent bite with any of the screwdrivers on hand, and even a utility knife. It just wants to spin around. I may try to pick up a couple of those little jeweler'* screwdrivers tomorrow, I've had many, but they get lost so easily! Looking at the new part, I can tell the hi beam switch isn't part of it. I looked online, and, considering previous recommendations, ordered the standard auto part from Rock Auto, should arrive Wed. Hopefully I'll get that snap ring off by then!

Sounds like an adventure!

When you get used to it, it goes more easily. I suggest adding a set of picks to your tool kit. The kind that has little and big and several angles.

Like for that snap ring, you can use a big pick to keep the ring from spinning and use a little tiny pick to get under it next to a groove in the shaft.

Either way, it sounds like you're able, determined, and still have a good attitude about it! That'* 95% of what'* needed!
