I have a '05 C230 with 5,400 miles on it.

Early this morning as I was leaving home, outside temperature was 78F (Texas) [8D]

Started my car and drove off, as usual, with aircon in "auto" mode, and desired temperature set around 70F. (I never touch the dials).

For the first time ever, the air coming out of the vents never got cold, I drove for around 10 minutes and all got was warm and humid air from the outside.

I stopped, tured the car off for 2 minutes and then back on, everything worked normally, cold air started flowing immediatly...

What do you guys think is going on?
Is this a random failure? Or is it a sign that something is going to break in the near future?

Has this happened to somebody else here?

That sounds like a bad expansion valve in the A/C system.

You need to have the dealer check that. It will get worse.

I had a 7 series BMW do the same thing as you mentioned. Once the expansion valve was replaced, the
problem stopped.

It could of course be something else in the system but what you mentioned sounds familiar.
