It's probably a heat shield, to protect the passenger compartment floor or fuel tank (or whatever is near the muffler) from excessive heat from the muffler. You could remove it, but why bother?
Where is the IAT sensor on 93 buick lesabre?
The IAT sensor is located on the intake manifold air cleaning housing or air duct.
How do you replace the rear turn signal lamp on a 2001 Buick Lesabre?
This is also documented in the owners manual. Open the trunk and remove the side-carpet retainer clips, these push-on, but need to be unscrewed to be removed. Once the clips have been removed, pull the side-carpet away, this will reveal the bolts holding the light housing. The nuts are 10mm, remove them and then push on the studs/bolts to push the light housing free. You can now access the light bulbs. Experience has shown that if one goes bad the others will follow shortly, so replace the bigger lamps and the smaller ones at the same time.
Where is the PCV valve for a 1990 LeSabre?
The elusive PCV valve does not leap out at you on the '90 LaSabre. Since, if your engine and it's spark plug wiring wiring is configured the same as mine, and hopefully it is for the sake of this answer, the PCV valve is hidden beneath those wires and, mostly, is further camouflaged by oil. Anyway, here's how you find the little sucker: As you stand next to your left tire, looking into the engine compartment, follow the 3 rear spark wires, from rear to front, ABOUT 3 inches PAST the REAR rocker arm cover. Pull the wires aside and look down a bit. There, at what might be called the south-west cornor of the rectangle engine block, if you consider the way you are facing to be "north", is the PCV valve. It's real close to the engine block. It fits stright down into its gromet with the hose the conects to the top/plactic part of the valve being only an inch long.
Can the starter solenoid drain the battery in a 1989 buick lesabre?
This can absolutely cause the drain. If the solenoid happens to be stuck in an energized position the battery will slowly drain.
A Good Way To Test++++Get A Light 12 Volt, Or A Voltage Tester From Parts House==Looks Like A Screwdriver, With A Wire Running Out Thr Top & Sharp Pointed On The Other End. Remove Your Ground Cable Connect Tester To Ground Cable, Then Connect Other End To Neg. Terminal ( This Will Be Between Ground Cable And Battery, Leave Hot Cable Connected. DO NOT TEST THROUGH IT. THE POSITIVE CABLE IS NOT REQUIRED FOR THIS TEST. IF YOU HAVE A VOLTAGE LEAK THE LIGHT WILL COME ON !!! IF IT DOES CHECK DIFFERENT ITEMS< WHEN THE LIGHT GOES OUT> YOU GOT IT.
I'd check the fuel filter first.
Why doesn't drivers window go up down?
Because it does go up and down I am 6 and even I know that all windows go up and they go down
might be the rain sensor
It's been an awfully long time since I've seen this, but I incline to a bad voltage regulator.
you'll need both a Philips head and a flat head screw driver. there will be 3 screws that you need to remove and several clip type fastenners (sorry don't know the exact name). one Philips screw is located near the door lock mechanism, on the part of the door that is hidden when the door is closed. with the door open you'll see it right away. another Philips screw will be near the door hinge at the lower part of the door trim. it is covered by a plastic cup that is the same color as the door trim. just flip the cup out and it will expose the screw head. the 3rd Philips screw is a bit tricky. it is behind the door handle (that thing you pull to open the door from the inside). pull the door handle and you'll see the screw. after you have removed the 3 screws carefully lift out the trim from the rest of the door. you will find several clips holding the trim to the door. use a flat screw driver to detach the clips one by one, taking care not to break the clips (they're made of plastic) or scratch the paint. putting it back, just position the trim over the door, and then push or snap the clips back by giving it a punch with your open palm. then install back the 3 screws.
suggestion: while you've got the trim out, it will be a good idea to squirt some wd40 on the locking mechanism and the window mechanism. or if you're up to it, remove the plastic that waterproofs the door, taking care not to tear it. them remove the old grease from both locking and window mechanisms, and apply new grease. then install the plastic waterproofing back. the plastic has an asphalt-like adhesive that glues it to the door, you can just tap it back.
I had the same problem with my 92 voyager when I bought it. For me it turned out to be the upper spring plates on the front struts. Had them replaced and it's been quiet ever since. NOTE: You might have to do an alignment if this is you situation as well.

Where is the sensor for the outside thermometor readout located on a 2002 Buick LeSabre?
It's called "ambient temperature sensor" and is located between the front grill and the radiator. It is slightly to the left of center of the hood latch.
Where exactly is the crankshaft sensor located on a '92 Buick Lesabre?
The dual Crankshaft Position (CKP) sensor is mounted to the front of the engine, attached to an aluminum bracket mounted to the left side of the engine at the timing chain cover. A 4-wire connector plugs into the sensor, connecting it to the ignition control module.
AnswerThe crankshaft senser is located under the dampener pulley. Remove the serpentine belt. Remove right front wheel. Remove plastic access cover that's behind that wheel. With an impact wrench remove dampener pulley bolt. With an Dampener pulley puller remove pulley. There is a plastic cover that snaps in place over the senser, remove it, and you will have access to the senser.EricWhere do you find a fuel filter on a buick lesabre?
Most GM fuel filters are under the vehicle, behind the driver.
How do you replace the headlight bulb located on a 1990 Buick LeSabre?
The bulbs come out of the rear. If you can't get to the back of the lights ytou have to remove them.
there are about 8 plastic wing nuts on each side behind the trunk carpet remove them and the whole assy will come out the rear
Edited: The flasher for the turn signals is usually located on or near the column under the dash. Unscrew the three screws holding the cover on. The flasher unit is that 1" cylindrical unit with two posts plugged in to a wire. To replace, unplug, and plug in a new one.
The hazard flasher is a separate system.
Unedited: Look at the hazzard flasher; usually in fuse box round 1" or square 1") to get an idea of what it looks like and pull it out; then when you think you have found the turn signal unit, plug it in to see if that fixes it.
How do you let air out of the struts on a 1994 Buick Roadmaster?
SIMPLE. Pull the rubber boot/air connector off the side of the Shock. The problem with the system is a small solenoid valve on the compressor. Easiest thing to do .................... JUNK YARD replacement
P0300 Diagnostic Code - Random Misfire
Symptoms.
Engine may stumble or miss
Engine may be hard to start
you may notice no issues
Cause
Failing spark plugs or spark plug wires
Bad coil or coil pack
Failing oxygen sensor(s)
Bad fuel injector or more than one
Stuck exhaust valve
Bad catalytic converter
EGR valve or valve passage clogging
Bad camshaft position sensor
Bad PCM or ECM
The Fix
Best first action is a tune up, new plugs, wires, inspect all hoses and wire connections then reset the code. If it returns you will need to narrow it down to a system, coils and coil packs should be tested, catalytic converters for function ( do you smell rotten eggs?). A misfire that jumps cylinders could indicate a lean condition, do you have any other codes along with the 300? this will help clue you in to the source, check valve function to make sure they are opening and closing fully.
This is probably pone of the most difficult codes to troubleshoot, so start with the basics and work your way into the more expensive options, in many cases a good old tune up solves the problem, back it up with a fuel system cleaning and see where you stand.
