Hi! Please check the fuse and relay boxes. Look for the trunk fuse and check if the fuse/relay is blown. If it looks good, just try to reinsert the fuse/relay for it may have just been tripped. HOpe this helps and have a good one!

2007 GT. Where do I check the hydraulic fluid?

Folding Top Fluid Addition
Caution: Refer to Eye Protection Caution in the Preface section.
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).
  3. ?‡'
    If the specified message is displayed, perform the TOP INOP-TRUNK Access procedure.

  4. 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 !

How do u close A tt soft top that has jammed halfway

e-z one here: first release hydraulics (as per manual) in trunk by turning the screw counter clockwise on top of hydraulic pump available by a slit in trunk carpet- then pull top all the way back (open), then pull forward all the way to windshield- pulling lever to open top usually will now be used to latch clamps to windshield- then to open the top pull lever as usual, top will detach from windshield and you then pull it all the way down towards trunk- I could do it while sitting in driver\'s seat- I did this manually for many years, after tiring of fixing, then breaking, over and over- became very easy after a while, to open and close by hand

Trouble with trunk lid staying closed goes down but comes back up

Please make sure your keys are not in the trunk because there is a safety mechanism that will not allow the trunk to stay closed if the keys are detected in the trunk. The other issue will be if the hold down mechanism is not pulling the trunk completely closed once the trunk engages the lock. You will then have to have it serviced to make sure the pull down motor is operating.
