First problem. When I raise the convertible to close it, latch the handle ... the dash signal for open or unlatched cover still lit. I also notice that the windows don't raise the last 1/2 inch after the latch closes like normal. Please tell me it's something simple????? Thanks, Charlotte

go see a local mechanic .

Did you take it to a qualified repair shop? Do you know what DTC'S - diagnostic trouble code's are ?

S3 and S4 are part of the Rear Compartment Lid Release switch. The folding top control (FTC) module uses S3 and S4 to determine whether the claws at the rear of the deck lid are latched into the deck lid or unlatched. S3 closes and supplies a 12-volt reference to the signal circuit when the claws are unlatched. S4 closes and supplies a 12-volt reference to the signal circuit when the claws are latched.

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.

Before taking this problem to the dealer, you might check this quick fix. I had the same problem on my 2007 Pontiac G6 Gt Convertible, and just resolved it.
First, you can access your trunk by disconnecting, and then reconnecting your negative battery terminal-this clears the safety code momentarily allowing the trunk to be opened using your trunk release button.
After you have the trunk open, check the wiring harness located in the top right corner of the trunk lid where the hinge is attached to the trunk lid. My wiring harness had come loose, allowing a wire to get stuck in the hinge, resulting in a cut wire-it was a red one. I spliced the wire back together, taped it up with electrical tape, and then secured the harness to the hinge assembly so wires couldn't come loose again. The problem resolved immediately with no further issues. Good luck.

Have someone pull the handle as you hit the center front of the hood with your hand. This helps to pop them up to unlatch them. Once open lube it till everything is loose again. May even raise the latch a bit. They are adjustable. If it still doesn't open, then you have to get under the bumper, with a long screw driver or pry bar and push the latch over. Look where the cable goes to the latch. You need to push it towards the cable.

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.

I did this to my car once. Be sure the latch isn't closed as you are trying to close the trunk. With the trunk open pop the trunk once, then see if the trunk latches properly.

i believe this model has a release latch in center of windshield at top correct? if so unlatch it and pull back on handle this is also the switch pull it back or push forward for open close

there should be a lever that is on the bottom edge of dash that is under the steering wheel along the trim. if the handle is broken you can use pliers to grab the cable and pull it to get the hood to realse. if you found all that and i seems to work ok then when pulling the release lever have a friend hit or shake the hood to get it to pop up a little so that you can open it all the way.
