The light bulbs appear to be a special bulb that used to be available aftermarket. But the problem is the switch and bulb are wired together. Replacement meant soldering. Also The switch is tricky to remove but can be by using paper clips and working the entire swtich up and out The leads are very short. I've read this in a Pontiac group.
 
I've not been able to be certain the bulbs are available nor have I had the nerve to try inching the switch out myself.

oil pressure gauge by rlrufus

I have a 1995 Lesabre with 202,000 miles. The car runs fine but I've noticed that after about an hour of driving the oil pressure gauge pegs itself. If I let off the gas it will come back to normal untill I have to touch the gas peddle the it pegs the gauge again. Can anyone help me.

It is most likely the sending unit. The oil pressure needs to be checked with a gauge that's screwed in to replace the sending unit. These do fail. Don't buy the cheap one; some of those are poorly made.

Steering Problem? by dave1081

Greetings - Last week I bought a very well preserved 1992 LeSabre with 116K. It looks great and drives beautifully. One thing I noticed is that at very low speed when making an "all the way" hard right (parking, etc.) I briefly (1/2 second or less) get a power steering hum and what feels like in the steering wheel, a slight jiggle. Happens pretty consistently especially on a bumpy surface but only at very very low speed and never during road driving. Anything to be concerned about??
 
I love this car!

This is getting a little weird... Today it did the little hum and jiggle thing and this time it made the steering wheel a little "off" i.e. I had to keep the wheel more than slightly to the left to go straight - even in a flat parking lot. When I did a hard right again and it did the hum & jiggle thing again, the steering wheel went back to normal. Now it rolls straight again when the steering wheel is centered. Any idea what this could be?? Tie rods? Something loose in the power steering mechanism? Will my wheels fall off? Doesn't seem to be any play in the steering... Help!

I am not an expert, but for my own diagnosis I'd get it up on a rack or jack up both wheels with jackstands. Move the car wheels to see if they are free to turn back and forth.-- no binding ball joints or tie rod ends. Take a close look at everything.
 
I'd suspect a steering rack problem. But it also could be a rubber bearing mount for the struts at the top that's not right. I had a fairly new leSabre that had one replaced under warranty> It would give a thump when it let go when it had bound up some> you could turn the steeering wheels with the motor running with the car on the ground on gravel or grass where the tires turn easier and feel the binding let go by holding your fingers on the coil spring>
 
You also could have a slipping belt on the power steering if it"s really worn> or you could have a power steering pump problem> have you checked the fluid level?

Thanks for the insight. I've had the car 1 week now. PS fluid level is fine with no evidence of leaking. I now notice a faint rocky-rumbling sound that is more pronounced when idling - similar to the sound I heard in the weeks before the water pump blew on my old Pontiac 6000. Water pump and alternator were recently replaced on this car so it might be the power steering pump starting to go?
 
Never drove a Buick before. Now I know what the "Buick Ride" is all about. Would like to think I'm too young for this car but I love it anyway.

You can use a long socket wrench and move the idler pulley enough to remove the serpentine belt. Then spin, push, pull, twist, the pulleys for all of the accessories just to see.
 
At 16 years without knowing what climate the car is in (extra hot?), my wild guess from reading forums and people's problems and what they turned out to be would be the harmonic balancer on the end of the crankshaft at the bottom of the motor. The thing is two parts with rubber between them. The rubber deteriorates and the two parts eventually can knock against each other, metal to metal, giving a knock most prominent at idle when the motor is going slow when the speed up and down with piston pulses are most obvious.
 
While you have the belt off, you might check to see if there's play between the inner and outer parts of the harmonic balancer
