1995 Buick Century

Electrical Problem

Had to drive in snowstorm other night, before snowplows were out for about 1/2 hour and about 2 blocks before I got home just driving down the road normally my headlights went out. Then I noticed because I continued on the hazards didn’t work. Looking behind I could tell tail lights were out and brake lights to. So started checking other things. Car was running fine and I got home and out of habit put on the turn signal to turn in driveway and it worked. So tried other side and it worked.

What Doesn’t Work

OK, now here’s everything electrical that went out. All I’ve mentioned so far plus rear defroster, power door locks, dome light and interior lights, gauge lights, horn, and it has a light under hood when you open it that was out(power windows still worked). Also I have 2 little blue led lights plugged into cigar lighter they were out. Everything else worked, Like the wipers, heater, windshield defroster Turn signals and like I said, car was running fine and normal and still is. Fuses all good! Now for even stranger part I come outside about an hour later and noticed those little blue led lights plugged in cigar lighter were back on. So I’m thinking alright, everything’s back on. So jump in and hit the headlights, hear a click and they did not come on. Little blue lights went out again and everything that didn’t before was back to not working again. Checked fuses and again were all fine. This is strangest electrical problem I’ve ever had! What it there something shorting out before going through fuse box or maybe headlight switch or, Oh and why do do turn signals work but not hazards??

Maybe I need a priest? Please help, I hate driving only when the sun is out…thank you.


RESPONSE

I would look at a loose or corroded connection at the battery. Quite common for an older vehicle such as this. No short or the fuses would be blown. You are loosing a connection that provides power to a lot of things. So either the negative or positive battery cable connections or cables are dirty/corroded or loose.

2005 Buick LesabreMy car suddenly made a high pitched squealing noise while moving. It felt like it was coming from steering wheel area But eventually grew to metal grinding noise sort of metal on metal then grinding gear like fly wheelish… Car has had lots of work, transmission is warranted – not labor, crv?

Don’t know need some ideas so I can take it to warranty place or ignore it, brakes have 13k on it and no chirping ever heard or. Felt


RESPONSE

Metal Grinding Noise

The first place to look for a metal on metal noise would be the brakes. This is the most common place for a metal on metal noise. It is normal for brakes to make a squealing noise before it turns into a metal grinding noise when there is a brake related issue. It is possible that you have a sticking brake caliper that has caused premature wear of the brake pads.

1998 Buick CenturyHow do I re-install the pulley on the harmonic balancer?


RESPONSE

First of all on this engine the pulley is part of the balancer. They are meant to be one unit. There is a rubber insert between the pulley and the outside of the balancer. As a result there is no way to re-install the outside pulley once it comes apart as it is a balanced unit. In conclusion a new replacement should be used if damage is found on the harmonic balancer.

Replace Harmonic Balancer

Removal

 The inertial weight section of the crankshaft balancer is assembled to the hub with a rubber type material. Therefore the correct installation procedures (with the proper tool) must be followed or movement of the inertial weight section of the hub will destroy the tuning of the crankshaft balancer.

  • Remove the drive belt.
  • Raise and suitably support the vehicle.
  • Remove the right front tire and wheel.
  • Take off the right engine splash shield.
  • Remove the crankshaft balancer bolt and the washer.
  • Remove the crankshaft balancer. Use a Balancer Puller.

Installation

    1. Apply sealant to the keyway of the balancer, this is especially relevant. Use sealant GM P/N 12345739 or equivalent.
    2. Install the crankshaft balancer. Use the J 29113/66515 .

    1. Remove the J 29112/66515.

harmonic balancer installation 1998 Buick CenturyCaution!First of all use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. In addition the fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener too. Most of all use the correct tightening sequence and specifications while installing fasteners in order to avoid damage to parts and systems.

  • Install the crankshaft balancer washer and the bolt.

Tighten
Tighten the crankshaft balancer bolt to 103 N·m (76 lb ft).

  • Install the right engine splash shield.
  • Install the right front tire and wheel.
  • Lower the vehicle.
  • Install the drive belt. Refer to Drive Belt Replacement.

1988 Buick Park AvenueI was looking at this car to buy it. When I went to drive the car, it was sitting in park at idle and I noticed a large amount of shaking. So I drove it up the road and the shaking stayed. I never drove over 35 mph. But I’d like to know whats causing the shaking before I consider buying it.


RESPONSE

Most likely there is a misfire in the engine causing the shaking. May be as simple as just needing a good tune up or could a burnt valve. Hard to say without doing some diagnosing.

Buick RegalI have a 1996 Buick Regal. Until recently, it’s ran fine. And then, this past Sunday (as of the time of this post), the RPMs began to shoot up to 5 and 6 and the car lost acceleration. I thought it needed more transmission fluid, but today I found out that I had put too much in it. So my dad and I drained the pan and refilled it, but the car refused to go into gear. Let me rephrase — it would go into gear, but it wouldn’t go anywhere. I found several posts on various sites about how it might be a transmission pump or a transmission lockup solenoid, but the results upon testing them were still the same — no acceleration at all. Does anyone know how this can be fixed without the need for a mechanic?


RESPONSE

If the fluid was burnt looking it will need rebuilt. If you hear a whining noise it is the pump.  If the fluid was pretty new looking then it is most likely an electronic solenoid sticking. This will generally set a code. The check engine light will not illuminate as it has to do with the transmission and not the engine. You will need a scan tool in order to pull the transmission codes. The codes will help point you in the right direction. Not much to do without the codes. Feel free to post them below if you have further questions related to this issue.

1997 Buick Park AvenueI have a 1997 Buick Park Avenue and when I flip the switch to turn my high beams on, they don’t come on. And my dash lights and side marker lights go off also. I have replaced the switch with a new one and it didn’t fix it.


RESPONSE

Looking at the wiring diagram it would appear as the only thing in common with both the high beam switch and the dash lights would be the Lamp Control Module other than the switch.
