Top wont let back or close

Principles of Operation
The convertible top will only operate with the parking brake engaged and the ignition switch in the RUN position. When the parking brake is engaged, the raise and lower relay coils are grounded through the parking brake switch. The convertible top switch supplies power to the raise or lower relay coil when raise or lower is selected. This power energizes the coil causing the relay contacts to close which supplies battery power to the convertible top motor/pump assembly. The normal state of the relay is connected to ground. When the raise or lower relay is operating, the other relay remains in its normal state supplying the motor/pump ground.

Inspection and Verification

1. Verify the customer concern by operating the system.

1. Visually inspect for obvious signs of mechanical or electrical damage.

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 .

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.

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.

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..

IF you can, separate the rubber/felt window seals and see if you can see the top of the window glass. IF you can - use a pair of needle nose pliers and attempt to carefully pull up - making sure you do not crack (shatter) the glass. Once enough glass is exposed - use your fingers to pull-up. While you are pulling--up attempt to raise (up) the window with the window switch. There may be a dead spot on the motor, by pulling-up you advance the motor beyond the dead spot, and the motor MAY re-engage.
IF you can't get the glass up with needle nose pliers, try pushing down on the glass (being careful again) while engaging the window switch to raise (up). Again the idea is to get the motor from the dead spot.
Another way: While engaging the window switch to raise the window - bang (hard) on the door - in various spots to attempt to "vibrate" the motor to engage.
Last but not least: Remove the Inner Door Panel and raise the window by hand, again using the window switch to (maybe) assist you.
I have also (but painfully): separated the window seals and got a piece of duct tape down onto the glass, using a long screw driver to adhere enough of the tape to the glass enough to pull up on the glass. It worked but it needs careful hand control on your part. GO Duct Tape!

Sounds like a bad microswitch on the 5th bow latch, you will need a Tech2 diag. tool to pinpoint the problem

Sounds like the sensor has faulted or the pump has become disengaged. Usually when the light is flashing it's a sensor. You can check for a pinched line or low fluid also. There is a manual lock overide procedure to get the windows up, it's in you owners manual.
Good luck...i hope this helps,

2007 Pontiac G6 retractable top engine swithed off while raising, top continued to close in compartment right side upper forward pad looking thing popped and the compartment would not close, however the top will raise and go back in place, cannot leave top in compartment since the trunk lid will not close over the stored top..........

The convertible top on my 1998 boxster would not work either, nor would the windows go down. If you have checked the fuse and it is fine, then it may be what I had experienced which is the switch located in the center console directly under the hand brake. There is a white plastic switch with a plunger on it that is engaged by the handbrake being raised. When the handbrake is engaged it activates the switch which then allows the convertible top to be activated. It's a $5.00 part, (I know, I couldn't believe it either) from the porsche dealer, and a very easy to do yourself job, it took me 10 minutes from start to finish. It would be worth spending the $5 and replacing it anyway, at least you could rule it out if it stll does not work you only spent $5 rather thank $140 an hour labor rate at dealer. Pop the side plastic panel under the hand brake on the drivers side and you will see the white plastic switch. Good luck.
