Question about Cadillac Eldorado

1 Answer

My neighbor bought a 85 cad convertible, but the motor to raise/lower the top won't work. I need the schematic for the raise/lower motor drive system, including the module attached.

    The module which contains the relay has been removed/lost. I need some type of schematic, to replace the missing module/ components.
    Thanks

    Don't have a schematic, but the problem is most likely the (raise/lower) motor relay which will be loacted near the motor, sometimes under the back seat.



    Best way to find it is to operate the roof switch and listen for a clicking sound -- the relay is making that sound.

Cadillac never built a 1985 Eldo convertible. It was custom made. A schematic will be difficult to find. Hope this helps

WHY WON'T THE CONVERTIBLE TOP MOTOR ENGAGE. WHILE DRIVING TOP BUTTON BLINKS RAPIDLY.


The top should not work above a certain speed or at all if the vehicle is moving. The top can easily rip from the wind if deployed at too fast a speed and even make the car unstabile while rolling.

Most tops will raise above the windshield height when they deploy and can fail to clear carports or drive-thru facilities. The tops can catch low hanging light fixtures or even garage door openings.

How can i get bmw 323i convertible top down manualy


If your top is electric then you will need to release the front cowl motors at the center point of the trim in front of the rear view mirror(small access plug needs to be removed and allen key inserted to drive unit.) You also need to pull the release handle under the back seat bottom(driver's side) The release handle detaches the drive units for the storage lid cover and the convertible top drive. Once the motors are released, the front of the top must be lifted approximately 6 inches and the pressure against the rear of the top will relax. raise the rear bow, open the storage lid, lower the rear bow and push the front of the top up and toward the back of the car. The top should fold into the storage area. Once in, close the storage lid until it clicks.

Top worked fine yesterday but today tried to let down only clicked


It is a hydraulic pump that applies pressure to the 2 hydraulic pistons to raise & lower the top. So, check for something obstructing movement first.

The convertible top:
  • is motor-driven.
  • requires parking brake engaged to complete circuit for operation.
  • is equipped with a back window glass (42006) . The back window glass is permanently attached to the folding top back window curtain (52500) and cannot be opened.

Convertible top not working


Before you even begin, I would check prices and availability. A lot of top parts for this are no longer available or VERY expensive. All parts are under panels in rear. Just be patient and remember where they go.

Lift Cylinder, Power Top Removal and Installation
NOTE: The cylinder rods should be in the fully-retracted position.
  1. Remove pump and motor as outlined.
  1. Remove the upper and lower hose fitting from the folding top hydraulic cylinder (50600) . Use absorbent rags or a container to catch any hydraulic fluid that leaks out when removing the fittings.
  1. Remove each of the service cylinder plugs one at a time and attach the hose fittings. NOTE: Be sure each fitting is installed in the correct position on the folding top hydraulic cylinder .
    NOTE: Make sure that the tetra seal is installed in the bottom of each of the folding top hydraulic cylinder ports before attaching the upper and lower hose fittings.
  1. Connect the folding top hydraulic lift motor and plate kit (533A00) to a 12-volt power source and cycle the folding top hydraulic lift motor and plate kit in and out several times to purge the air from the hoses. Some noise squeal may be noticed due to the air.
  1. Carefully remove the rubber fill plug from the back and the reservoir and check the fluid level. The level should be at the bottom of the filler hole. If necessary, add Synthetic Mercon® Multi-Purpose Automatic transmission fluid E6AZ-19582-B (ESR-M2C163-A2) or equivalent.
  1. Replace the fill plug with a new fill plug.
  1. To install, reverse Removal procedure.

Convertible top's motor is out, is there another way to get it up?


you will have to find out where the motor is and disconnect the arm or mechanism on the motor and then you will be able to pull it up manually also just check the fuse for the top motor if you havent already hope that helps.
