Buick LeSabre Electrical/Lighting
I own a 1998 Buick Le Sabre. Today I experienced problems with turn signal. The turn signal lights are on but the flasher doesn't work on the left side (front and back) What could be the possible problem?
Thanks

I'm a frequent poster on Edmunds, but have never had one as crazy as this. My '97 LeSabre's check engine light came on a few days ago. The car ran well enough with it on for a few days. The light even went off briefly. However, this morning, the light had returned, and the car refused to shift out of first gear. Additionally, the input to the pedal did not directly correlate with the motor's reaction. Strangest was my fuel gauge, which now randomly meanders between 1/2 tank and empty and settles for awhile before wandering again (I have a little bit less than a half tank remaining). I took it to a local auto parts store where they ran the trouble codes. TPS was listed as one of the codes, and so I replaced it. The car now idles well enough, but still refuses to shift out of first, and the TPS trouble code refuses to be erased when clearing codes with the OBD II. The clearing of the codes appears to have settled my idle, and replacing the TPS has made my pedal input better correlate with the motor's reaction. Additionally, the fuel gauge problem appears to have righted itself, but the car still won't shift out of first.
My friend suspects the problem lies in my Electronic Control Module, but he admits he doesn't know GMs all that well. I have the following questions:
- Does anyone else think this is the likely culprit?
- Would a repair shop be able to use their Snap-On Diagnostics to better pinpoint the problem?
- Is there any sort of traceable relay that might be fouled between the computer and the transmission?
- How likely is it that the problem resides in the transmission (I had it flushed a little more than a year ago)?
I appreciate any thoughts on what's ailing my car. Thanks.
You might post a question in the above discussion. Alcan or others may know something to check. There is a fuse panel above the passenger's right kick panel--someone said it can be reached without taking off the hush panel, but I believe the hush panel has a list of the fuses there. A fuse there may be related.
A connector next to the driver's left foot for the grounds sometimes causes problems with corrosions or moisture. There is another ground beside the driver's seat under the carpet between it and the door and one on the passenger side. Grounds at the instrument panel next to the emergency brake could be gas gauge problem or connector going to the back to the tank.
A first thing to check is the connections on the battery. Take the ground off. Take off the two positives and clean everything and check cables the contacts connect to in order to make sure they aren't eaten away by battery acid. Is your battery good? After you clean and replace the cables, check voltmeter for the battery operation.

So please don't post in the discussion imidizol97 suggested. I'm sure he didn't realize you'd already posted so many times. The people who read the discussions you've already found also read the one he suggested, so you'll reach the right people.
I hope we can help you with this.
If the VATS system reads the wrong resistance it locks up the starter after 3 turns of the key for 5 minutes or less. Then you can try again.
If you find that it is the wires or contacts in the cylinder and you choose to bypass see the link:

You have to find the two wires at a connector down by the base of the steering column. The two wires may be inside a small orange wire which is really a tube.

ps thanks for the info! if you have more let me know or if you have more ideas!

My thoughts are fuel pressure regulator and maybe a coil or wires. Everything looks original from plugs to wires etc.
Any ideas?

Put those on. That sounds like it could be spark scatter where the spark is not able to fire across the thin mixture under light load at speed. you feel it most when the torque convert has locked up at 45-50 in 3rd or 4th and you are accelerating slightly to hold speed up a slight slope.
Second would be fuel filter. You can replace that yourself with jackstands. It will on fuel lines under right side of the car either in front of the rear wheel or under the passenger's feet. That last location requires good safety knowledge using the jackstands; rear location can be done without them.

Update to follow tomorrow.

It also acts up more when hot than cold - another sign of an electrical problem/weak wires.
If this does not work, then off to coil packs. I know how to test an old fashioned coil. Any idea how to test a coil pack?
I suspect you'll fix your problem with new plugs and wires. Good luck getting the back plugs out easily...
2014 Malibu 2LT, 2015 Cruze 2LT,
I replaced the plugs and wires and 95% of the problem is gone. I also changed the oil and fuel filter.
Looks like I got off cheap.
You'll notice a difference in a few miles.
Since the car has high years but low mileage, I suggest trying that.
You've been busy changing all that in one day. Report back.

What is the damage if I keep running it for a while? (0% of my driving is on the highway above 60mph.

did they check the sending unit at the connections back by the tank to see if the sender was working correctly? Or did they just throw a part at it again since they had a boat payment due?
The problem sounds like it is connections or dash gauge problems. I'd have to check service manuals to see the full circuits.

weeks ago. I took it to the closest dealer earlier this week, and
they told me I needed about $3000 in repairs on the car,
ranging from a new transmission to brakes, and other various
things. I asked what would turn the light off, and they said to
replace a soleniod, which was stuck open. So i had them do it,
and about 20 miles later, the light came on.
So I went today to a mechanic recommended by a friend and
they ran diagnostics for me. It came back with a P0741 trouble
code (torque converter clutch circuit performance or stuck off),
and they told me to drive it until the light came back on and
then call them and bring it back in. Well, driving home from
work tonight, again after about 20 miles, the light is back on.
What kind of repairs should i expect to fix this problem? Will the
transmission need rebuilt, as the dealer initially suggested?
You didn't say how many miles you have on the car. Let us know.
2014 Malibu 2LT, 2015 Cruze 2LT,
The car has 77k miles on it.
Perhaps I'm getting overly-sensitive about it, but the car seemed sluggish as it drove.
The check gets run, on my car, when the motor is slightly warmed up but not fully hot, and the motor is restarted. E.g., my temp gauge was just part way up to normal and I stopped for coffee. Came out and when I restarted the check was done and the light went out.
The temp is for example between 130 and 170 degrees. I'd have to look through my service manual to find the reference again.
If the light didn't come on right after a restart like that, it may not be a pollution check light; it may be from other causes.

I have just had my second incident with my car and its headlights. They are supposed to illuminate when the car is turned on to either the DRL's or the Low Beam Headlights, which ever the car's sensor determines (so I'm told).
The first time this occurred (about 3 weeks ago), I took the car to my local service center (not G.M. or Buick) thinking that one of the bulbs was burned out but when the mechanic took out the driver's side bulb, the passenger side illuminated. He then put the driver's side bulb back in its space and it also illuminated. He thought that there might be a shorted or nicked wire but could not get the problem to re-occur.
Tonight, I went to use the car and once again, the Low Beam lights did not illuminate. The amber "parking lights" worked, the rear lights worked, and the High Beam lights worked. I'm thinking that maybe there is in fact a wiring problem, but would like to know if any of you have experienced this issue or if you can advise me as to what to have checked before a dealer's service dept. rapes me to do a general electrical check.
Thanks for your help,
Bill

the tire ripped apart the wiring harness and whatever mounted to the small bracket.
