It was 86 degrees or so yesterday, and I'm driving along A/C on (full AUTO mode, set to 69 degrees). The fan was about halfway ... car was still very hot from being in the sun all day.

Suddenly I feel warm air. I look and the green light next to the snowflake button was out.

I pressed it again, green light went back on and everything seemed normal again. Cold air blowing, fan working just fine.

Was this some sort of overload protection, or is this a symptom of something bad about to happen? I drove around with the A/C on without any further incidents so I'm thinking it was just a one time thing.

The only time was yesterday. It's not even peak heat here... I've driven in much hotter without any problems. Unless it was a weird power fluctuation.

Hmm, keep an eye on it. If it happens again, abuse your tech guy :D

Haven't heard of that one in particular, but I have recently heard about a known fault with an E46 A/C resistor that's causing some other weird A/C problems (mostly concerning the fan speeds going higher/lower on their own). Wonder if this could be related in any way.

No Zaino in the A/C... I promised myself that. :)

But on recycle mode it could have absorbed some of your Z cologne:rolleyes: :dunno:

Never happened to me in a BMW but I have seen this on long, extended trips through California in the middle of the summer in a crappy Ford Windstar. The A/C compressor would shut itself off after a long, extended period of use and you'd have to cycle the button to get it back up and running. That was a 6 hour drive up to S.F. from Bakersfield (had to make NUMEROUS pit stops for my grandfather) for my cousin's wedding in Marin County.

If it's an isolated incident I probably wouldn't think twice about it. It could have easily been the button was stuck or something/someone in the cabin touched the button.
