I can not get my tailgate window open. The release does not work at all, only to open the whole hatch.
Anyone know how to fix this?

well I guess the fog rear light do not work aswell and rear wiper, too. Right? it is the cable to the tailgate.. they break frequent.

Usually the problem is with the hatch wires. Its pretty typical with tourings. First you should check your wires form roof to hatch, both sides. My english isnt very good, so i add a picture where i mean :)

A hammer would be the best solution if you don’t mind rain.
