rear gate lock/unlock switch not working

[Lapprentis]

In my, case, I did cleaned the switch mecanism like other suggested but frankly, it was not very dirty..So, when disasembled, you will see some rocker arm - balancier a few mm long that are solicited each time you used the sitch. I simply bent it back delicately (about 1mm or less) the opposite way the pressure is put on everytime you used it. Et Voila. Put some WD-40 and works prefectly now on. Be carefull on dimanteling to NOT loosing small parts, springs, etc.
