Hi all, can anyonehelp with tailglass tailgate problem on my L320 2010 RRS. I have read allposts relating tailglass. My upper tailglass tailgate worked fineuntil one day it stopped opening. All the fuses are fine, no warningsigns and no OBD2 error reading. I can open the whole tailgate butnot the upper. I have made sure that the whole tailgate is closingproperly even by closing the lock with a screwdriver. I have removedthe switch and it has 5v and an earth, shorting these out does notopen the gate. The switch has no corrosion, has good resistance andthe switch works fine. I have removed as much as I can of the insidetrim but as the top is still closed I can not remove completely. Theinside lock has 4 wires to it, anyone with ideas what wire to trip itopen? Some people have mentioned programming the key remote to openthe tailglass but as it’s a 2010 model the manual says a dealer isneeded to change the option from tailgate to tailglass, any methodother than the dealer? Thanks in advance for any help.
