I have a 1997 E320 with dual zone air.

All of a sudden I am getting hot air out of the drivers side and cold out of the passanger

I am in Florida and of course it is not the oposite with cold comming out of the drivers side instead

Help its hot out here!!!

most issues discussed in forum, i just been thru whole a/c issue, if its low its a leak somewhere, or refer to DIY post on doing a diagnosis using climate controls. -use search and type in a/c. you'll get it all, but like i said, most likely a leak

I have freezing cold comming out of one side and hot on the other

I would think this is a vent issue or a control issue

Help its 95 degrees

run the tests and errors,punch them into the program.
Either low on 134a which will cause warm on one cool on the other or a stuck duovalve.
give them both a tap with the end of a screw driver handle.
Diy for location of duo valves on benzworld.org w210 section
post the values and error codes here after you have ran the tests.
