2006 ML 500 Climate control issue: temps don't change!

Hi guys,

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.

Every now and then ours will not let you increase the temp and will only lower the temp. The way we found to advance the temp was to half turn up to the edge of the detent, and that will up the temp, but don't go past the detent, this will up the temp on ours. Other times the temps will advance or lower with a spin of the ring.

Mark.

I took it to the dealership just for them to look at it, they say with a software re-set ($175) they may be able, if not, they have to replace the whole part which will cost around $850 or so, not good news for that crappy piece of plastic
