Trunk lid wont open or close cadillac xlr

Most cars with dead battery you can turn key, then lift handle then turn key more to manually unlock (driver's door).

Do you hear a click noise at all? You could try this.. One person sit on the truck lid, (heavier may be better) relieving the lift tension on the lock, while the other person push the button and hold. Sitter then hops off and pulls up on the trunk lid. If not working, Sitter person could try gently bouncing on the trunk lid while you hold the button.
Groceries still in trunk after 3 months???
If no joy, then you need someone to replace or remove the lock and pop it with a screwdriver.

There is obviously a problem with the trunk release solenoid in the trunk. You will have to do it the "old school" way and use the KEY to get the trunk open. Once you get it open, inspect the wiring conduit that runs between the body and the trunk lid. You will most likely find the problem there where the conduit bends back and forth each time the trunk is opened and closed.

adjust the mechonisom on the lid and or latch catch on car

it may be as simple as adjusting the catch.....cheers

There is a actuator are on the deck lid latch,,, its small and plastic and the most common piece that breaks .this will keep it from latching and drawling down..
if its this the actuator will need replacing ..

Do you mean the pulldown is not working, or the trunk lid latch is not connecting to the pulldown assembly when you try to close the trunk?

This latter case typically happens when someone slams the trunk lid down several times not realizing there is a pulldown system and thinking slamming it will make it close (this often breaks something). Check the latch on the trunk lid - if it's in the closed position, use the key to try to move it to the open position and try gently closing the lid again.

If not, there is also a switch on the pulldown assembly that starts the pulldown motor when it is depressed by the closing trunk lid - you can also check this to make sure it's working. Otherwise, either the latch or the pulldown assembly has been bent/broken.

Replace thr pulldown switch .

You have a pull down switch that activates the pull down motor for the trunk lid to close. The manufacture of this part supplies this to Ford & General Motors vehicles. You can go to a Cadillac dealership & purchase this part far cheaper than at Ford. I use to work at a GM dearlership & my neighboring Ford dealer would order this part from me for the cost of mine where less than the cost from Ford. Figure those guys out at Ford. No wonder they don't need a goverment bailout

The problem is that your roof(SOFT TOP) lid isnt closing properly. If you open the roof lid you see there is a button on one of the latches that tells the car that the roof is securely closed if your roof lid is not secure the trunk wont open. To test this press down on the roof lid and the try to open the trunk.
