Oldsmobile Cutlass Ciera

My right turn signal works fine the left turn signal wont. It makes all the lights flashers tag light dashboard lights even the radio flash like emergency flashers. I have replaced all bulbs, flasher fuse and the blinker assembly in the steering column and it still does the same thing please help.

This is not a common issue. There is a wire that is crossed. If there has been recent work done, start there first and recheck the work. Look at aftermarket installation of radio, remote starters, etc.  The next step would be to try a replacement multi-function switch(turn signal switch). There may be internal damage in the switch causing the issue. And this is a common failure component.

Turn Signal Switch Replacement

  1. Disconnect battery ground cable.
  2. Remove steering wheel as outlined under “Steering Wheel, Replace” procedure.
  3. Using a screwdriver, pry cover from housing.
  4. Using lock plate compressing tool No. J-23653, or equivalent, compress lock plate, and pry snap ring from groove on shaft, Fig. 1. Slowly release lock plate compressing tool, then remove tool and lock plate from shaft end.

  5. Slide canceling cam and upper bearing preload spring from end of shaft.
  6. Remove turn signal (multi-function) lever.
  7. Remove hazard warning knob retaining screw, button, spring and knob.
  8. Then Remove pivot arm.
  9. Wrap upper part of electrical connector with tape to prevent snagging of wires during switch removal.
  10. Remove switch retaining screws and pull switch up from column, guiding wire harness through column.

I have a 1988 Oldsmobile 88 with a burned out turn signal. I am trying to figure out how to reach the bulb to change it out. Can’t seem to reach it from the top. Do I pull the whole headlight assembly out? If so, how? Or is there an easier way? Maybe up on a ramp and get to it from underneath?

Turn Signal Bulb Replacement – 1988 Oldsmobile Delta 88

The replacement of all the light bulbs is straightforward. First look for the easiest way to access the connector. If you can reach under the car to the connector with your hand, then you won’t need to remove the lens assembly. When there is no way to reach the bulb or the connector, you must check for an access cover or see if the lens cover has screws. If the lens is secured by screws, removing the lens would be best access to the bulb. If the lens has no screws showing on the outside of the vehicle, then access is from the back side. Once you have access to the bulb, simply grasp the connector and turn counterclockwise to align the slots, then remove the bulb from the lens housing.

loud ratcheting noise while making turns, f, dissipates on acceleration, occasional pop when changing lanes or further acceleration. have replaced both cv half shafts and sway links. does make vehicle noticeably move when turning

If I had to guess, I would look closely at the front hub bearings. This would be the most common cause of noise while turning.

There is a vacuum connector that pulls air in but whatever line connected to it broke off and disappeared. No one can tell me where it’s supposed to connect to. Autozone employees are all saying it’s definitely affecting the engine.  Here are the images:

shows position on the front of the engine

Just a closer picture

Thanks. Driving us crazy.

Vacuum hose connector

It is my opinion that this hose goes to the MAP sensor. I am guessing the upper intake has been removed and when put back on the hoses were not set correctly. I am also going to guess if you extract the diagnostic trouble codes from the computer you will find a code indicating a MAP sensor issue. Use the diagram below to help assist in locating the MAP sensor. I think (3) is the end of the hose in the image you provided.

Transmission Problem

Will shift out of park but when shifted into any gear there is no response. I can hear the engine idle change when I shift but there is no feed back from the transmission.

  1. Check transmission fluid level – How to check fluid levels
  2. Check to make sure both axle shafts are present
  • If the fluid is burnt looking or low there may be internal damage. Top off level if low and test operation.
  • If the fluid level is good and the color of the fluid is clean and pinkish, the most likely cause for the issue would be a failed solenoid inside the transmission.

Starts then dies

Owned vehicle from 70,000 -166,000 current mileage. I have reset Passlock several times. But this time it starts then dies. I removed battery 30+mins cleaned terminals .replaced.left ignition on AAC for 10mins turn off pull key tried starting same as before starts and dies it recently had new ignition coils plugs wires module $1200 .the shift lever button popped off couple years ago( Hockey tape works great ) all fuses look good maybe ?auto shutdown relay? At same time car stopped so did door locks/trunk release..can hear fuel pump.

My first guess would be the ignition switch. I think these had an issue with the ignition switches. But when it will not start you should determine if it isn’t getting spark, fuel or both. Also check for fuel injector pulse. I do not see a relay involved according to the wiring diagrams.

Anti-Theft wiring diagram 2001 Oldsmobile Alero


Starter Circuit Description (LA1)

Moving the ignition switch to the START position sends a 12 V to the PCM Ignition Crank Voltage Sense. At the same time a 12 V signal is sent through the PNP switch then through the coil side of the STARTER relay. The PCM verifies that all parameter a met for starting. The PCM then grounds the control circuit of the START relay. When the START relay is energized it allows voltage to the starter solenoid S terminal.

Overheating 2000 Oldsmobile Alero 2.4 GLS

Now it’s overheating

Car was running fine until I changed the radiator hose that was leaking. Now it’s overheating and I’ve replaced, thermostat, reservoir, flushed the system, checked radiator, I’m at a loss. Someone suggested water pump but if it was the water pump why would the car not overheat with a leaking hose but once fixed it began to overheat? It has to have something to do with some type of ventilation the hole in the hose was giving the system. I have also “burped” the system several times.


Make certain all leaks are fixed. Make sure coolant level is full with 50/50 mix. Straight water or coolant will cause the engine to overheat. No thermostat or stuck thermostat will cause an engine to overheat. Something to consider is one of the caps is bad since it does not overheat with a leak. Replace radiator cap and or overflow cap.

Cooling System Refilling Procedure


When adding coolant, it is important that you use GM Goodwrench DEX-COOL™ coolant. If coolant other than DEX-COOL™ is added to the system, the engine coolant will require change sooner: at 50 000 km (30,000 miles) or 24 months.
•Close the radiator drain cock.
•If previously removed, install the engine block drain plugs.

When installing the drain plugs, use pipe sealer GM P/N 12346004.


On vehicles equipped with the 3.4L engine, open the coolant air bleed valve. The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.
•Fill the surge tank to the base of the filler neck.
•Start the engine with the pressure cap off. Run the engine until the upper radiator hose starts to get hot.
•If the coolant level in the surge tank is low, add the proper mix of coolant until the level reaches the full cold line.


After servicing the cooling system, and if the vehicle is equipped with an intermittent low coolant light, an occasional low coolant light may be encountered during some extreme driving maneuvers. This complaint should be eliminated by removing the surge tank cap and adding coolant to a level just at or above the full cold line when the system is cold.
•Install the cap onto the tank with hand tight pressure.

1998 Oldsmobile 88Driving down the road engine just shuts off. Sometimes it starts right back and sometimes not. All electric still functions. No check engine light comes on.
Problem is sporadic. Possible coil pack? Plugs and wires have been changed. Seems to be more electronic than a fuel system problem.


Engine shuts off

Sounds more electrical to me as well. Difficult to pin point the cause on these intermittent problems. When it won’t restart is when you can perform some tests. Since it doesn’t happen all the time it is difficult to diagnose. My GUESS would be a failing ignition control module or crank sensor/wiring harness. The ignition control module is directly underneath the coils.

Ignition Control Module Replacement

Removal Procedure

•Disconnect the 14-way connector from the ignition control module.
•Disconnect the spark plug wires from the coil assemblies.

ignition module 1998 Olds 88•Remove 6 screws (1) securing the coil assemblies to the ignition control module.
•Remove the coils (2) from the ignition control module (3).
•Take off the ignition control module.

Installation Procedure

•Attach the coils to the ignition control module. Refer to Ignition Coil(s) Replacement .

Caution! Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. 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. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
•Install 6 ignition coil attaching screws

Tighten the screws to 4-5 N·m (40 lb in).
•Install the nuts and washers securing the ignition control module assembly to the mounting bracket.

Tighten the nuts to 8 N·m (70 lb in).
•Connect the spark plug wires.
•Connect the 14-way connector to module.

Jumping the car doesn’t work 2002 Oldsmobile Intrigue

2002 Oldsmobile IntrigueI have a 2002 Oldsmobile Intrigue that started with the heater blower not working and now it won’t start. Found a blown fuse for the high blower and replaced it. I even replaced the starter that looked old. The headlights are bright and the radio/dash seem to be strong as well. I have tested all of the other fuses with a test light and all seem fine. Seems to be electrical but can’t pin point the problem. Also, jumping the car doesn’t work either.


Jumping the car doesn’t work

Jumping a car rarely works after a battery has been run completely flat. Your vehicle had a short in the system and is why the fuse was blown and may have also run the battery flat. The most common reason for a no start is the battery. Either bad connections or the battery itself. If the battery is close to being 4 years old, replace it anyway. It takes very little amperage to operate the radio(5 amps) or the lights(7 amps) as compared to the 250 amps needed to turn the starter motor. You can check for battery voltage at the “S” terminal at the starter when someone holds the key in the “START” position to check the circuit.

Still Won’t Start

There is the possibility of an electrical issue in the starting circuit. Start with a fully charged battery. Check for battery voltage at the involved fuses. Check for output voltage at the starter relay. Look for voltage going to and from the neutral switch. Repair the wiring in between if any loss of voltage is indicated. Use the starting system wiring diagram for reference.
