2006 ML 500 Climate control issue: temps don't change!
here is my issue, when I tried to run my AC manually today, it didn't change my temperature (driver's side), the passenger's was fine, so testing it out and fiddling with, I decided to put the passengers temperature around 76- heater- and now it won't change down to where I want.
How to solve this issue, I read somewhere in here people had problems with it as well.
