Hi Qc2 , I did as you suggested and it worked a treat , I sprayed a liberal amount of WD40 in and around the boot door handle using the tube attachment, and left it for half an hour , when I tried the handle there was full movement but the door didn't open, so I locked and unlocked the doors using the key fob , and tried again and...Hurrah !! it opened and has been working ever since....Thanks for your great advice it is very much appreciated....cheers 🍻
