Question about 1991 Cadillac Allante

Open Question

On my 1991 Allante the convertible top when folding and lowering hits the pull down motor even after adjusting the pull down motor location so what can I do to adjust the top so it will fit in the boot correctly without damaging the rear window rubber seal.

GM uses bent metal clasps to secure the visor position. If you are mechanically inclined you can buy buy new clips for roughly $10 and install them yourself or do what I would do which is remove what is there is gently bend them back to an oval vs the circular shape they have now. There should be two philips head screws holding the assembly. Remove the two screws (per side) an slide the visor off the mount to reveal the metal clasp. Should you have any questions simply reply back and I will do my best to help.

Good Luck

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

07 corvette top will retract but deck lid makes no effort to close, then top will not go back up. Need to release pressure in block lift top up about 1/4 of way then top will go back up


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 unfold the top and latch per normal procedure.

Manually Moving the Folding Top from the Up Position
Important: Allow the system a minimum of four minutes to bleed down pressure after the last cycle.
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 .
DTC B3666 Rear Tonneau Position Error
DTC B3667 Tonneau Release Circuit
DTC B1011
DTC B1291
DTC B1420

Allante problems


If the pull down motor hums, then it is effectively functioning but obviously isn't catching the roof hold down mechanism..Behind the driver's seat and under the panel you will find a switch that when you activate will cycle the unit and you release when you it the clicking sound and you have to ensure that you hold the rear of the roof down when it cycle for the proper pull down action...Unfortunately this seems to be a problem of engaging and the car has a history of this issue...I have encountered this everytime and it is a question of the rear being engaged for proper function...
good luck

Convertible top


Taken from answers .com There are several fuse boxes on the Cadillac Allante. I know that, in particular, the 1993 Allante has a fuse box in the trunk, right next to the battery, underneath the ashtray assembly, and then one more in the engine compartment. For the one in the trunk-- lift the trunk. Facing the rear of the car, looking at the back window, move over to the right rear wall of the trunk and flip up the panel there. It is a carpeted panel that is not obvious. Shake that panel a bit and you will see that you can flip it up. I believe it has some Velcro tabs that keep it down. There is a fuse box sitting there inside the shell of the body once you open that flap. You won't miss it. For the one by the battery, which is located within a shelf behind the passenger seat---slide the carpeted shelfing facade towards the passenger's seat.

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.

1996 saab 900s , cont. top didnt work at all, had "check latches" message. checked the system,pulled it apart and found the motor was installed incorrectly. had motor and position sensor...


You need to hook up the car to the factory tool, and check for codes. I think the lower limit for the main or 5th bow potentiometer needs to be adjusted. lots of service information at www.saabservices.com in the convertible top section

Cannot put top up on 1987 allante the latch is locked in and icannot open the latch on the pull down motor


There's a switch ( kinda same shape, color & operation method as your power seat switches) behind driver's seat near the 2 Boot/Top 'release' pull tabs,, it's mounted on the "roof" of the open compartment area behind the seats. Slide your hand along there til you feel it. It recycles the pull-down motor up & down & should release the top. Also try in the trunck, there's 2 hard plastic strings with loops at end,, pull & see if it releases it.
