2004 350z storage lid will not close all the way when top folds in the storage compartment

look for a blown fuse or a bad relay or bad sensor. possibly the mechanism is in a mechanical bind .. i would go to youtube and search the issue to see if it's a common problem and if so there will be videos on fixing it ..

What make ,model an year vehicle ? Could be a sensor or a control module . Some of these convertibles are very complex , could set DTC'S diagnostic trouble codes .

Folding Top Fluid Addition
Caution: Refer to Eye Protection Caution in the Preface section.
Important:
?€¢
When servicing the hydraulic system do not allow the fluid level to drop below the minimum indicator line on the reservoir.

?€¢
Inspect the hydraulic fluid level with the vehicle parked on a level surface, the folding top in the closed position, and the stowage compartment lid open.

?€¢
When new, the power folding top hydraulic fluid is golden clear. As the system is cycled, it picks up the carbon black from the numerous O-ring seals used in the system. The carbon black acts like a dye and causes the fluid to darken considerably and take on a black appearance. This is a normal occurrence and no repair attempts should be performed, as replacement fluid will also darken.

Place a protective covering over the interior and the adjacent body panels. Locate the hydraulic pump in the folding top storage compartment area on the right side. Remove the rear quarter trim panel. Refer to Rear Compartment Side Trim Replacement - Right Side . Place a shop towel around the pump motor to control any hydraulic fluid spillage.
Important: Wait 5 minutes before separating the hydraulic cylinder lines at any connectors.
Remove the reservoir filler plug. Add fluid GM P/N 88901975 or (Canadian P/N 88901976) ONLY, add the fluid until the level is at the middle of the indicator line on the reservoir.
Notice: Refer to Fastener Notice in the Preface section.
Install the reservoir filler plug.
Folding Top Deck Lid Access
In the event that the rear compartment lid is inhibited from conventionally opening due to a folding top symptom, displaying a TOP NOT SECURE message or that the folding top operation can not complete the opening or closing sequence as it is inhibited by the rear compartment latch being ajar, displaying a TOP INOP-TRUNK message, follow the steps below to determine the specific Tech 2 Special Function to gain access.
Important: Allow the system a minimum of three minutes to bleed down pressure after the last cycle.

1. Ignition On, engine OFF.
2. Press and hold the folding top control switch. Verify the TOP INOP-TRUNK message does not appear in the driver information center (DIC).
?‡'
If the specified message is displayed, perform the TOP INOP-TRUNK Access procedure.

3. Press and hold the folding top control switch. Verify the TOP NOT SECURED message does not appear in the DIC.

If the specified message is displayed, perform the TOP NOT SECURED Access procedure

Your better off to take it to the dealer - Chevy ! no Pontiac any more !

The retractable hard top is controlled by the folding top control (FTC) module.

If your top is electric then you will need to release the front cowl motors at the center point of the trim in front of the rear view mirror(small access plug needs to be removed and allen key inserted to drive unit.) You also need to pull the release handle under the back seat bottom(driver's side) The release handle detaches the drive units for the storage lid cover and the convertible top drive. Once the motors are released, the front of the top must be lifted approximately 6 inches and the pressure against the rear of the top will relax. raise the rear bow, open the storage lid, lower the rear bow and push the front of the top up and toward the back of the car. The top should fold into the storage area. Once in, close the storage lid until it clicks.

There are 4 elastic bands inside the top that pull certain roof support bars back...much like a set of vertical blinds that need all slats moving together at the same angle. If the elastic bands are stretched & worn out... a bar going across the roof (side-to-side) stays forward and does not let the roof go back. This happened to mine. My mechanic taught me how to do the manual procedure (also in the owner's manual) but I also had to move that bar myself toward the back of the car in order for it to fold down back in it's bay. I took it to the dealer and he had an upholstery guy reach in and replace the 2 outer elastic bands for a nominal fee. He could not replace the 2 middle elastic bands without tearing the roof material apart. But the top works fine for now. He said it should last about a year or so before the bands stretch out again. He also said to put the top up and down at least once every 2 weeks to keep it functioning properly. When the top is up (over you head) the bands are fully stretched.... they are relaxed when the top is down.

Unlatch the top on the inside and push it back a little. Then get out the car and lift the rear of the top where it meets the compartment lid. Open the roof storage compartment lid, the latch is inside the car behind the drivers seat. Fold the top into the compartment and close the lid. Make sure it latches. If you have further queries, please leave a comment.

it sounds like the storage lid is jaming for some reason investigate you will see the problem

hello, it sounds like the tension straps for the top are stretched. when the straps get like that, they allow collision between the storage lid and the rear bow. I would recommend having the straps inspected to see if they can be pulled tighter, or if they need to be replaced.

This is a professional job for a conv. top shop. has to be sewn in at the bottom.
