My trunk release will not work using the decklid button. The key will mechanically open the trunk, as will the dash mounted electric switch. Trunk lights go out when I push the latch mechanism with a tool. A simple test of the decklid pushbutton switch indicated a properly working switch. The ground is good at the decklid. I guess my next stop is at the security module? Have any of you resolved the same issue? Thanks in advance!

 

Here is how to fix the problem https://www.jaguarforums.com/forum/x...-button-74403/

 

My car has to have the same issue. Thanks very much! I will give that a look!

 

I developed the same problem this weekend. I will give this fix a try!

Thank you!

 

Ok. I had a few minutes to remove that harness, and cut it open to have a look. Sure enough... one of the wires was completely separated. A second wire looked suspicious, so I cut it apart at the "bump", slid some heat shrink over the wires, and soldered both. I wrapped it all back up, and will install it tomorrow! Thanks VERY much for the tip! Incidently, I called my Jag parts dealer to see if they even had a harness, and they said they couldn't find the part number. Told me to just repair it. I see the number is right on the harness tag:"LJG3085AB" for my 2004. I thought it might be $25 or so. Ahem.... MSRP is $173.00!
