I have a 1989 260E with 77,000 miles on it.

The air conditiong blows very cold--most of the time...

Intermittently, however, when the AC is blowing, hot air will suddently start to blow out the side vents (has only happened a few times, so I'm not sure if it blows out the center vents as well).

I can get the system to blow cold air again immediately if I press the "0" button on the pushbutton control unit and then turn the AC back on.

Has anyone have an idea what my system's problem is? Is it the pushbutton control unit? Or is there something else going on inside the system?

Thanks in advance for your help!
