Convertible top and rear windows will not close

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, the convertible top operation is disabled.

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.

3. Your best bet ,take it to a qualified repair shop !

look around your convertible top and its like you have problem with the black seal some thing there make your convertible top not close good . try look again and i hop you found the problem . look good .let me know .

Got kids? VW electric convertible top - I found dried milk in the switch had same problem on turn on convertible opened and would not close, would have to use manaul bypass foldup. Pull window controller spray with a electrical cleaner then try it. If not dirty the switch is bad. May be in driver door switch or on rear door? Good luck.

the cd transport mechanism is plastic when it breaks its f..... you will have to replace it,sorry.as far as the window is concerned,put the key in the door and unlock the car holding the key over will lower all windows,then lock the car and hold over the key,the windows will go up.(that resets the windows and SHOULD reset door rollback.)if not its a computer brain reset.

Manual roof procedure
The procedure in the manual is just for closing the top.
A) Turn key to OFF for several seconds to bleed off hyd pressure.
B) Turn key to MAR (full electrical, but before start)
C) Remove cap on bulkhead behind the right-hand seat and use flat head screw driver to unfasten the hyd unit valve in order to relieve the oil pressure in the circuit.
D) Remove the cap on the bulkhead behind the left-hand seat and using screwdriver or allen wrench press until the top covering (panel behind roll bars that covers the convertible top well) until the panel's locks are released - you may have to tap the wrench to release the locks.
E) Lift the top covering manually and keep it open while extracting the top from its well.
F) Remove top from well until the front part is near the windshield frame.
G) Lift the rear part of top (rear window) upwards and lower the top covering until the hooks are resting on their respective locks.
H) While still keeping rear part of convertible top lifted upward press Button 1 to attach the top covering locks.
Button 1 is the forward one
Button 2 is the rear one.
I) Make sure locks are fastened. if not - try pushbutton 1 again. If necessary repeat D and H
J) Rest rear part of convertible top on top of covering.
K) At front of convertible top, open (deploy) the top's hooks by using allen wrench to turn the pin mechanism. (located in center of front headliner)
L) Press top unto windshield frame and use wrench to lock the hooks.
M) Press the rear of convertible top, so hooks on rear top insert into respective slots and press Button 2 to secure.
N) Keep Button 2 pressed until hooks properly fasten.

If the top is still tightly latched at the front, you can just start at step "G":
While holding the back of the top in the air, and the "top cover" resting down on its "hooks", press button 1 until it seats well.
Then lower the back of the top down to mate its "hooks" and press it down while holding button 2 until the top seats well.

to lower the top,

insert the trunk key into the key hole just to the left of the driver's seat and turn it 1/4 turn.

push in the red handle stabilizer and then pull down on the handle near where your head would be when driving

repeat for the passenger's side

lift up on the front most part of the convertible top and push slightly towards the rear.

holding that in place with one hand, pull back and then up on the backmost part of the convertible top leaving it inverted on top of the rest of the cover, or at least, up out of the way of the cover door.

once that part is up, you can let the front part go back forward

pull the cover door release lever near the keyhole mentioned in step one.. there are two latches one for the back seat to fold down, and one for the cover.

lift the cover door up and fold the back part of the convertible top back down to its original position

lift up again on the front most part of the convertible top and push it back, this time it should go back fairly easily and start to lower the back part of your top into the compartment. as you do this bit, it will be helpful to keep the rear window from buckling too much so as to avoid deformation.

when it is about 2/3 of the way in, you will want to push upward on second support bar from the back in the convertible top, if you dont, it will buckle up and not allow the top to fit in, and if you force it you will break your top.

once it is all in, you can shut the cover door and remove your key.

to put it up,

put the key in the aforementioned key-hole and turn it 1/4 turn as before.

pull the compartment latch and lift up on the compartment door.

pull the top all the way up so that the front of the top is resting on the windshield.

pull up the back part of the top so you can shut the compartment door

(seems obvious, but just for completeness sake) shut the compartment door

lift up on the front-most part of the top and push it slightly back to give your self slack to push the back part down and into place.

pay attention to both sides as you push the back of the convertible top into the groove on the top of the compartment door. (in it's shut position)

once it is in place, guide the plastic ridges on each side of the convertible top into the grooves on the sides of the compartment door.

from inside, pull the handles down so that the hooks on the bottoms are extended.

put each hook into its respective hole, and push the handle/lever into the closed position so that the red handle sabilizers snap into place.

the end.

The convertible top motor and release lever are in the luggage compartment.
From the Bentley manual, the following general procedure is suggested in order to close the top in an emergency situation.
Main motor. To release the top linkage from the motor, lift the left corner of the rear seat to access emergency release handle.
It is then possible to push the top manually to a near closed position. In case of the semi-automatic top, simply attach and lock the front latches.
Front latches. Once the fully automatic convertible top has been released from the motor and manually pushed to near-closure, emergency latching of the top is possible by using the S-shaped hex key provided in the emergency tool kit(attached to the trunk lid underside).
First, remove the the plastic cover over the latch motor in the front bow of the convertible top.
Next, use the hex key from the tool box to crank the front latches shut.

After a manual raise or lower of the convertible top using the red latch behind rear seat....Gap in cover near window right ? Unhitch the cover on the passenger side rear near gas tank and inside you'll see the convertible motor. The rear level disengages the motor so you can move the top manually. Snap the motor back into place and then push the top control to fully close the top eliminating the gap. Then you'll have to find out why it stopped in the first place.

Try using the all windows up and down button (Drivers side on door), evidently after you change your battery this is the reset proceedure.
