My fuel door button and the trunk button wont open could it be a fuse

Did you check for a loose electrical connector on the trunk lock mechanism? There was a small two prong connector that was loose on my 2001 Pontiac Grand Am I connected it and the trunk button on drivers door now works and when I get a new key fob I am sure it will work.

Solenoid that opens the door catch
You can push the button & have a volt meter on the
solenoid wire,to see if you have power to the solenoid
That will pretty much confirm the problem & test the
entire circuit with one test or check

It sure sounds like a fuse. You can check for proper voltage at the hot wire of the actuator while you try to pop it. I think you are overlooking the fuse. Make sure the actuator has a good ground as well.

You have listed the vehicle is a 1987 Jaguar XJ6. The trunk is not electronic and only unlocks with the key as well as both the gas doors. Any issues here then it is your key or the actual trunk latch. If you do have a 1988 model year then the trunk lock has 3 positions. locked all the time, unlocked all the time or the vertical position locks and unlocks with the vehicles drivers door lock. If the trunk button (paddle) is loose and moves but nothing happens then the inside rod has come loose and you will have to manually operate the latch by removing the license plate and taking a long screw driver through the lower plastic bungs. The fuel flap is a separate unite and does have a manual release but you need to open the trunk to get to it. If the fuel flap stays locked all the time then the actually filler neck module will need replacing.If you have a 1997 which has the electronic release button to open the trunk (95-2003) Then you will need to firstly lock all door and unlock the drivers door 2 times. Check the fuel flap is now released, if not then the fuel flap actuator located on the filler neck inside the trunk is bad. If the trunk does not open with the remote, inside car switch and trunk mounted switch then the passenger side trunk harness is broken. Open the trunk with the key and on the right(passenger) hinge there is a grey plastic cover, remove that cover and carefully peel back the wiring harness cover and you will find 1 or more broken wires. Once the wires are repaired then I recommend you zip tie them in place and retest the trunk release button.If this does not answer any of your questions please feel free to email [email protected]

So the key wont open the trunk? there should be a pull cable in the trunk near where the gas door is to open the door.

Hello: Please check the valet switch in the glove box if it is on, turn it off and try the trunk and fuel door. Also there are 2 fuses for this system. The fuses are in the trunk compartment fuse block. They are labeled as follows:radio/phone fuse 10 amp and convenience fuse 20 amp. The round key should open the trunk, if not then it might be the wrong key or the trunk lock cylinder may have been replaced.

there is a cabel in the trunk that you can pull to open door same side as fuel door usly has yellow handel on it say fuel door

with a 12 volt test light check fuse ( #22 not entirely sure, or in the 20's ) 20A fuse blown. controls both trunk release and fuel door. Hope this helps.

I had the same problem last fall and had my mechanic check all fuses, he could not find the problem. Later my son was in the glove box and then I remembered the valet button disables the trunk and gas door so the person parking your car cannot snoop in your trunk or get to your gas cap. push the valet button in the glove box and see if you can release the trunk and gas door. Hope this works for you, it can be a pain opening the trunk every time you want to put gas in the car....good luck...........

Check the fuse panle under dash panel/ The actual push botton may need to be replaced if the fuse is good/ Please rate my response thank you very much
