A/C vent temp differences
Has any one noticed a temperature difference between the center vents and the right side passenger vent. With A/C running, no matter how I have it set, normal or recirculate, the temp out of the passenger right vent is not as cold, measured over 5 to 8 degree warmer. A/C set at 68 deg, center and left temp will be 55 deg and right will show 60/62 deg. Air volume is the same all around so not a blockage problem. This is the same when in a shaded garage or out in the open. Any thoughts.

Thanks for your reply, I just had a chance to ride with a friend who has a '14 E sedan and his A/C seems about the same, not as cold thru the passenger vent as the others. Must be an MB thing. Seeing Dealer next week for my smell issue I poster earlier, seems to me to be exhaust or some sort of gasket leak thats causing this. Will ask about A/C temp then.

This is the best AC troubleshooting page there is, so vote it for stickies as I am getting tired of posting the same link hundred of times on forums.
When W212 doesn't allow for reading the sensor values on the dashboard (at least I did not find it) - all other principals are the same on MB for last 20 years.
So find a scanner who can read the sensors and if you don't know how to interpret them - post them here. Read the notes at bottom of the page for better instruction.
