Couple 2011 GLK issues
Also there is the annoying and very noticeable, high-pitch "hissing" sound from the fan blower no matter what speed the fan is set to operate - any of you also have this? and cure?
Thanks all.

As for the hissing sound, that might be a misaligned filter in the ventilation system. When I changed mine I didn't have it seated just right and it would hiss too like air was going through a small gap somewhere. I readjusted the filter to fit properly and it went away. Just a guess. Your issue might be something else.
