Disconnect the battery negative cable, carefully remove the door panel, make sure you remove all the visible hold down screws holding the arm rest and other things in place, be careful and observant, don't force anything. If you don't have the standard door panel removal tools, use a stiff putty knife or a wide screwdriver to remove the door panel, you will have to get the power window control switch and the lock control rods out of the way, take notes so you know how they go back together, Remove the plastic weather protection shield out of the way, try not to tear it because you will want to replace it using a good contact adhesive. Getting the motor and the lift mechanism out is the biggest challenge, There are two big rivets holding the motor and regulator assembly to the door, there are two more rivets closer to the rear of the door that holds the track and window guide in place. the rivets are difficult to drill out because it's not easy to center punch them. I used my 4 inch grinder to remove the rivet heads, be careful not to injure yourself or grind through the door metal. knock the rivets out. Remove the power supply wire from the motor. Use a 10 MM socket to untighten the two cap screws that hold the lift bracket to the bottom glass channel. Don't take the cap screws all the way out. Use a piece of wire to hold the window in the closed position. Loop the wire over one of the hold down cap screws and fasten the other end through one of the convenient holes near the top of the door. Now comes the good part. the motor and lift mechanism is all in one near rigid piece. The seat belt anchor blocks the door panel opening that would make it relatively easy to remove. Don't give up, the unit will come out with some thoughtful manipulation, the V shaped track guide will tolerate a small amount of flexing, don't overdo it. I finally got the assembly out by moving it as far to the back of the the door cavity as possible, use the angles of the assembly to your advantage to free it from the door. Once free, use a black marker to ensure you align your new motor in the correct postition. If you are replacing a complete assembly that looks the same a the part you removed, install by reversing the above directions. If you are replacing only the motor, drill out the two rivets that hold the motor to the lift assembly. this will be asy to do. fit your new motor in the exact same position, referring to the previous marks you made. If you are reusing the old lift mechanism, you should pull the perforated tape out of the guide, clean, inspect it, the guide and the tape, relubricate it, I used white grease, there is probably a better grease available. The motor assembly I received from an internet supplier came with rivets and machine screws to install the assembly, I used 1/2 quarter twenty nuts and bolts to replace the big rivets, I don't have a big enough rivet gun. If you go the quarter twenty way, use thread lock, install with bolt heads on the inside the door and flat washers and nuts to the car interior. Be observant, I left the plastic bracket that attaches the drive tape to the window bottom in an unsecure place, one of my dogs used it as a chew toy,so it was off to the junkyard one more time. Be sure to secure the tape properly at both ends. If it worn or frayed, several suppliers including rockauto supply them at reasonable cost. good luck.

Sounds like it could be the fuel pump or injectors.

SOURCE: The windows in the 95 oldsmobile cutlass ciera won't work at all

maybe the wire is severed where the door (drver dr) pivots. thats what was wrong with mine. there is a rubber boot with crinkles in it that hold all the wires together. you can also try replacing the switch board that controls the wndws on the drvr dr. hope that helps.

What is the best oil for a 1989 Cutlass Ciera


If you have no oil leaks.. I would use a synthetic or synthetic blend in the 5w 30 range. Look for oils made for high mileage engines, but that is not essential. 120k is not that high.

1989 Oldsmobile Cutlass Ciera leaks oil on back side of motor. Where are the possible locations of this leak?


that all depends on how high the leak comes from, it could be from the intake manifold gasket if its high up on the motor,, a little lower would be around the bearing seals , and lower yet could be the pan gaskets ,, keep in mind that a lot of wind is generated when the motor is running at high speed, and a leak from the front of the motor could be blown to the back very easily.

89 Cutlass Ciera stalls when stopped. plugs have been changed, wires, fuel pump. Any thoughts on what is wrong?


With a good air filter, and a good fuel filter you shouldn't really have any problems since the fuel pump is good. You could have a vacuum leak, this can be identified by using a can of carb. cleaner with the tube attached so that you can spray near & around your vacuum hoses & connections. If you spray near a leaking hose, or a cap, or connection that is leaking, the engine will slow or stall. Only spray a second or two & allow the engine compartment to air out between spraying as it is a flamable product.

Short of that, you could be looking at ta idle speed control motor/throttle position sensor.

Testing the vehicle with a vacuum gauge could assist in identifying any other issues such as exhaust or valves. Gauges usually come with instructions & just need to be hooked to an available intake port.

good luck.

Fuel Filter seems like it's attached, but leaks.


De-pressurize the fuel system. (un-plug the fuel pump wire or fuse and crank the engine a bit) Remove the fuel filter and check on the fuel filter tubes and inside the connectors for the "O" rings. They can become damaged during removal and this usually causes the leak. Additionally, check the new filter itself for any damage.

Leak at Driver's Side Door (dripping slowly)


Body leaks are very, very hard to pin point, mechanics usually want to go home when they ge one, but here is the way we track them down, if you feel the leak is from under the put a sprinkler hear under the car and turn it all full blast get inside and try to see where the leak is coming from, if the leak is from up top area then do the same thing, let the sprinkler rain on the car, as much water as possible, once you do find the leak get some body caulking or a can of spray under-seal and spray the leaking area, it is most likely a welded seem that is leaking. GOOD LUCK.
