Common prob. with early xk is the hood fluid turning to jelly, the answer is to clean out the system. ie pipework, resovoir etc. to open the hood, open the valve on the pump, located in boot rh, remove blanking plug in headlining. use allen key to release forward hood latch,the hood can then be worked manually.to change the fluid you have to remove the forward hood latch. disconnect pipes, press the hood switch to pump out the old fluid,remove the pump and drain out the old fluid, work the hood manually 3 or 4 times to extract the remaining old fluid, the correct fluid to put back is pentosill it will bleed itself.if this is not the cause of the prob. then its electrical. go to a auto electrician you will need a wiring diagram of the system to sort that out, its got loads of relays e.t.c. and is controlled through the body processor module.

Manually Moving the Folding Top from the Down Position
Important: Allow the system a minimum of four minutes to bleed down pressure after the last cycle.
Manually release the folding top cover latch using the emergency release cable.
Raise the folding top stowage cover.
Manually raise the folding top, holding the 5 bow up.
Manually lower and latch the folding top stowage cover.

Manually release header latch per normal operation.
Manually lift front of roof off of the header and raise the #5 bow at the same time.
Manually release the Folding Top Cover latch using the emergency release cable.
Fold the roof down into the well.
Manually close and latch the folding top stowage cover.

Power Folding Top System Components
The power folding top system consists of the following components:
• Folding top control (FTC) module
• Body control module (BCM)
• Folding top control switch
• Serial data communication
• Folding top cover latch actuator
• Folding top cover pull down actuator
• Folding top pump motor with valve manifold
• Position switches and limit switches:
- Pin receiver switch
- Luggage barrier switch
- Folding top cover open switch
- Top open switch
- Top closed switch
- 5 bow raised switch
- 5 bow lowered switch
• Tonneau release relay
• TONNEAU PULL DOWN ACTUATOR Fuse 20 A
• TONNEAU RELEASE Fuse 10 A
• BATT 2 Fuse 40 A
• REAR FOG/ALDL TOP SW Fuse 10 A
• Folding top mechanical components:
- Folding top
- Folding top cover
- Folding top valve 1
- Folding top valve 2
- Folding top valve 3
- Hydraulic lines and cylinders

Folding Top Cover Latch Actuator
The power folding top system includes a folding top cover that is powered open and close by a hydraulic system that is controlled by the FTC module. A power unlatch motor is used to unlatch the folding top cover before the folding top control (FTC) module powers the top cover open. The folding top cover unlatching is requested by the FTC module via class 2 message, but is executed by the body control module (BCM). When requested, the BCM applies battery voltage through the folding top cover release relay control circuit to the tonneau release relay. The relay is energized and battery voltage is applied through the folding top cover release control circuit to the latch actuator. The actuator is energized and the latch releases the folding top cover.

The electronics on this are very complex ,

System Operation
Before any movement of the power folding top is allowed, the folding top control (FTC) module must be aware of the following conditions:
• Unlatch the header. The FTC module reads the pin receiver switch is Inactive.
• The windows must be normalized. Refer to Power Window Reinitialization.
• The ignition must be placed in Accessory or RUN.
• The transmission must be placed in PARK, or with manual transmission, the park brake must be applied.
• Trunk status must not be ajar.
• The luggage barrier must be in place.
• The pump motor temperature must be within the operating range.

After the last cycle of power folding top operation, allow the hydraulic system a minimum of 4 minutes to bleed down before attempting manual operation of the top.
Your best bet take and have it checked for DTC'S - diagnostic trouble codes .

Top will not come up. trying to by pass the lift


John, I'll help if I can. Need more info first. Does the top go down under its own power? Can you hear the hydraulic pump running (whining) when you try to raise the top? Does it move at all and give up or nothing at all? Did the top operate more slowly for awhile before failing to raise at all?

Let me know, and I'll see if I can help narrow down a potential solution.

How does a manual top work on a 1998 BMW 323 I??


I believe you do this in this order. Roll windows down, release the latch at the top of the windshield, raise the front of the top, release rear cover by pulling the latch near the rear seat, Pull up the back of the top and then pull up on the rear cover. The back of the top should now fit into the opening under the rear cover. Continue to fold the top into this space. Push down on the rear cover to lock (won't be able to open trunk if not engaged.) To raise it, release rear latch cover, open rear cover and pull top out of opening. Raise rear of top so you are able to now close the rear cover, set rear of top down on cover and then pull fron of top down and engage the fraont latch. Hoe that 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.

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.

Slow to raise top and now nothing...


The convertible top on your car has two hydraulic cylinders on either side (they are hidden behind the trim panel by the back seat) that move the top up and down. They are prone to leakage. By your description I would speculate that they are the problem.

Can I manually raise my Convertible top on my 1994 Chrysler Lebaron gtc


You can, but it will probably take two people and they must move the top slowly and together. It will be hard because you will be forcing the fluid back through the pump.

You can change it to a manual top by removing the bolt at the top of the cylinders and lowering the both shafts down into the cylinders.

1996 BMW 318I Top will only go part way down and stop.


hi bunkeyh, try helping the top when it stops by continuing the movement in the open direction. if it continues operation you probably have bad convertible top straps. another tell-tell sign is if the rear section slams down on the cover or does not hold position. you should be able to reach your hands under the canvas and between the liner at the second bar of the top frame from the windshield to check for sagging or weak straps. in anycase the straps will need to be replaced.

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.
