Question about 1989 Ford Mustang

1 Answer

1989 convertible top has worked great, today putting it down, it stopped just about down, now the relays back by the pump just click, click, click when I press the switch. I changed the relays and they still make the same noise with no motion up or down, Can a switch just stop working out of the blue? or is it a pump? The guy I bought the car from said he just replaced the pump motor, Can they just go bad? out of the blue?

Yes they can but it sounds like the "after load switch" sticking up,,,not the pump,,the top has a switch that tells it when its fully closed and this switch turns off the pump,,i would look at this first

05 mustang convert.no open/close,makes clicking sound.2 relays,fuse,switch checked,new motor/hydraulics.Are there other relays,open close sensors? Top works UP when grounded externally, but not DOWN.


Principles of Operation
Convertible top operation is controlled by the smart junction box (SJB). When the convertible top raise/lower switch is operated, the SJB commands the front and rear windows to the full down position. Window operation is disabled while the convertible top raise/lower switch is being operated. When the SJB receives a full down input for both rear windows, it commands the appropriate relay closed to raise or lower the convertible top. If the SJB does not receive a full down input signal for both rear windows, convertible top operation is disabled.
The convertible top assembly is a floating frame, Z-fold design. The main pivot brackets are attached to the body, and the convertible top frame side rails expand or fold when the convertible top is raised or lowered. The LH and RH stay pads are attached to the convertible top frame bows, and provide the main source of tension for the convertible top material. When the convertible top is in the full down position, it stores in the compartment behind the rear seat backrest. When the convertible top is in the full up position, the body provides a stop which the convertible top frame number 5 bow contacts to provide a weather seal for the convertible top against the body.
The convertible top hydraulic system uses a 12-volt reversible pump and motor assembly. When active, the pump uses hydraulic pressure to extend the hydraulic lift cylinders to raise the convertible top, or retract the hydraulic lift cylinders to lower the convertible top. The convertible top motor/pump assembly is equipped with a thermal circuit breaker. The circuit breaker typically resets after 5 minutes depending on the ambient temperature. The thermal circuit breaker cannot be repaired and must be installed as a unit with the motor/pump assembly. In the event of a hydraulic system failure, the convertible top cannot be operated manually.

  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.

I have a 1996 chevy silverado 2500 every once in a while it will stop running,when i pull the fuel pump relay out and put back in it starts back up. it is very warm to the touch,just noticed today tha


I would just replace the relay. Then if it still happens, your fuel pump is drawing too many amps. Causing the relay to overheat and shut off. Time to replace the pump, before it dies on you.

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.

  • Damaged folding top hydraulic cylinders .
  • Damaged folding top motor upper and lower hose .
  • Damaged convertible top regulator.

  • Circuitry open/shorted.
  • Damaged convertible top switch.
  • Damaged raise/lower relay .

1995 Jaguar convertable XJS quarter light windows wont go up


The rear windows are controlled by a timer in the top's ECU. If
the rear windows stop fully closing before your top is closed, the
problem MAY be with top's hydraulic system.

Check your top's hydraulic reserve tank for low fluid level. Lack
of fluid will greatly delay the top's closing sequence, leaving
those rear windows partially open.
Your top's hydraulic pump system is located beneath the right side
of the cubby/storage box behind the front seats. Raise the cover
and you'll see a removable trim panel on the right side. The pump
is behind that access panel.

You can use power steering fluid to top off the tank, but don't
fill it above level indicator line. You may have to add more fluid
after you cycle the top up and down to get the air bubbles out of
the lines.
It could also be a relay. On a 95 the relays that are in the trunk above the battery.
Perhaps, just switching the relays might prove which one is failing..

something is heating up it could be the ignition relay or a bad ignition switch. relay can over heat and stop working this would take some time to cool down again, ignition can do the same some times you can feel the heat on the key when removed.

I have a 2005 PT Cruiser. The convertible top was down. When I went to put it back up, I had no power. The fuse was fine. I bled the pressure off the cylinders and manually put the top up. The wondows on...


HYDRAULIC PUMP/MOTOR ASSEMBLY Any diagnosis of the power top system should begin with the use of a scan tool and the proper Diagnostic Procedures Information. The scan tool can provide confirmation that the Controller Area Network (CAN) data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the CAN data bus, and that the power top motor is being sent the proper hard wired output by the driver window regulator module.


NOTE: The convertible top system is equipped with a hydraulic bypass screw that is used to relieve pressure from the hydraulic system in the event that the top must be manually raised or lowered (such as a low battery or a convertible top operating concern). Always verify that the bypass screw is tight in the pump housing prior to replacing a hydraulic pump/motor assembly (Refer to 23 - Body/Convertible Top - Standard Procedure). If the power top is completely inoperative and the hydraulic pump/motor assembly is suspect, perform the following:

(Refer to 23 - Body/Seats/SEAT BACK - Removal).(Refer to 23 - Body/Convertible Top/ASSEMBLY, Hydraulic - Removal). If not OK, use a scan tool and the proper Diagnostic Procedures Information to complete diagnosis of the power top system.

On convertible vehicles, the convertible top switch is hard wired to both window regulator modules by the Power Top Switch Mux circuit. When a top operation input is received by the driver window module, it will ground the respective relay control circuit which in turn will operate the motor. If the convertible top switch is pressed and held to the down position second detent, it will command both modules to drop all windows to the fully down position. The windows cannot be raised when the convertible top switch is in the top down position. When the switch is held in the top up position and all four windows are fully up, the modules will lower the respective front window 40 mm (1.6 in), lower the respective rear window approximately 55 mm (2 in) and the driver window module will ground the top up relay control circuit. Once the top is back up the windows will not raise automatically.

Your missing that you don't have a clue on how the electronic's on your vehicle work . Your best bet , take it to a qualified repair shop . Your trying to fix something you have no clue on how it works , going at it blind .

1989 mercedes 300e can the fuel pump relay be reset or does it have to be replaced? is there a way to check it?


autohaus.com is a great place to get relays, usually cheaper than anyone. Normally the fuel pumps just go bad tho. I checked my pump with 2 wires while the car was of and put straight power to it.

Convertible Top Not Working Properly


This is not a low fluid problem, this a contorl motor problem. I had a 1989 Z24 conv. and the same thing happened. I replaced the motor and the top worked just fine.
